Re: [meteorite-list] SLAGADOCIOUS / Interior photo?
Well... Congratulations Carl. You are the first to let the Cat out of the proverbial bag. The find (and just a reminder as I have seen some posts, I never said it was a cold one) is a pairing with Cat Mountain and I hope the MetSocCom will approve Cat Mountain 001. It was spotted fifteen minutes into an eyeball hunt on Snyder Hill in late March not far from the published location of the original find of the late Mr. William Goldup in the early 1980's. The area is now extremely trashy and too popular with the kids on bikes and ATVs. Heavily used dirt paths all over and a four lane paved road and a subdivision within spitting distance. Someone with better skills than mine, with a VLF tech detector, might be able to work subsurface and do some good as this meteorite has substantual metal. The hill has been worked hard since this find by several hunters with just a few grams of unrelated chondrite found. Good luck to anyone else going on it. The interior is a little darker than the exterior and all the white you see is metal. The interior is as dark as a carbonaceous chondrite. The best way to describe the exterior is igneous melt with all kinds of blebs and layers..just like slag. This rock got hammered hard, and repeatedly, in its cosmic life. That's why the classification carries an S3 to some of it S5 description.

Re: [meteorite-list] SLAGADOCIOUS / Interior photo?
So you're walking the paths of William Goldups, Guido, who discovered CM as an unusual looking dark stone on a walk in/close to Tuscon in 1980. As far as I know Mr. Goldups' assumption that the stone could have been freshly fallen at the time he found it, got a scientifical confirmation later, right? In any case: you took Bob Haag's footnote (see below) to heart: CAT MOUNTAIN, Arizona This amazing little meteorite was found in 1978 by a Tucson gentleman who walked through the desert every day to buy his morning newspaper and coffee. One morning he spotted a small impact crater in the sand, at the bottom of which lay this rock. He swore up and down it had not been there the day before, so he picked it up and put in on his mantle, then called me to take a look. On the exterior it didn't look like any meteorite I'd ever seen, but you never know, so I offered to take off a tiny sample to look for metal grains or chondrules. Unfortunately, he refused to let me touch it, so it sat on his mantle for another eight years until his death, when his son inherited the stone. The son took the piece to the University of Arizona mineral museum where Shirley Wetmore finally convinced him to allow a corner to be ground off, confirming that it is infact an absolutely unique, anomalous, impact-melt breccia, one half chondrite, one half achondrite meteorite! You can see the large clasts of melted H-chondrite surrounded by totally vitrified material. A footnote: diligent searching of the same area by several different people turned up one more specimen of Cat Mountain, roughly the size of a pecan, about 1,000 yards from where the first piece was found, some fifteen years before. (Hello? Get that? Go back and research places where meteorites have already been found. You might get very lucky if you know what to look for.

[meteorite-list] Cat Mountain Precautions
Now that the other half of the story is out and the cat is out of the bag, I can hear the sounds of 4X4s being fueled, tuned up, loaded and ready to head out. For those who are not familiar with the area, I would like to advise using caution. Temperatures this time of year in the Tucson area exceed 105 degrees on a daily basis. This may not sound like much to us who live here in the Southwest but if you add in the fact that this is also Monsoon season, the humidity will make it even more dangerous. Stay out of the wadis (washes) as flash floods are a real danger during the Monsoons. I think somebody drown in a nearby intersection just a few years ago. Swinging a metal detector up on a hill in Monsoonal lightning storms is not a good idea either. I only mention this because I have seen hunters lose all common sense once meteorite fever sets in. If you are not used to the desert, you can easily become dehydrated without realizing it. You have to drink at least twice the amount of water than you normally would elsewhere. This is very difficult to do since your body will not absorb most of it unless your potassium and electrolyte levels are up. I think half of your hydration needs comes from food itself so you cannot instantly acclimatize. I have heard of people dying within a half an hour stranded on the side of the road. Something as simple as trying to fix a flat tire in 120 degree heat can be deadly if you are not used to the high temperatures. Carry several gallons of water in your vehicle, not just a pint. Please cover your digging holes and be respectful to land owners. A few less-than-considerate people can ruin it for the rest of us.

Re: [meteorite-list] clusters of holes on the ground on Mars andEarth -- impact swarms: Dennis Cox: Rich Murray 2011.07.30
Thanks Sterling, I know what sinkholes look like too. The New Mexico craters number in the thousands. I've been checking the Geologic record, and digging into the literature, for more than a year now. I have written to many of the top planetary scientists at NASA. None of them has been able to tell me of any actual science that's been done there. Although, the discovery of a single interconnected cave system that covers thousands of square miles would be just as big a deal as clusters of small impact craters covering the same area. They are found in a large enough quantity, and variety of terrains, to rule out karst collapse as the cause with a fair degree of confidence. I've had it up to here with uniformitarian assumptive hand waving. And I don't see it as anymore valid than some of the pseudoscience I've read. The most entertaining of those is the one from the Velikovskian delusionists who tell me they are caused by interplanetary electric discharges. And after two years of digging in the literature, I really don't give a rip either way. Can someone tell me who has done some real science there? Regards, Dennis Cox -- From: Sterling K.

Until we’ve been there on the ground. The reasons are these. The crater-counters have identified 220,000 unambiguous craters of every age on Mars, exclusive of any volcanic or ambiguous features, of which there are many thousands, but they are a tiny minority. On the Earth, the number of verified craters is less than 200. I grant you, many more will be verified, but the Earth should have 2.6 times as many on its land surface as Mars does, 500,000.. It did, cumulatively, have that half million craters, but they are gone because the Earth is, as the freshman geology cliché has it, a dynamic planet. On the Earth, the default assumption for a hole is geological process (of whatever kind). On Mars, it is Splat! And both are likely right in the first approximation. I bet if you checked the geological literature, you would find that many of these features have been visited. Perhaps not investigated with impact in mind, but it should be possible to isolate those with no obvious terrestrial cause.

[ http://www.space.com/2295-supercomputer-takes-cosmic-threat.html ] The colors in the simulation we see in the below video, are graded by temperature. White = 5800°K - 5527°C Red = 2000°K - 1727°C http://www.youtube.com/watch?v=Gr7i33UhmC8feature=player_embedded Simulation of an asteroid exploding in Earth's atmosphere, taking into account the momentum. [ 21 second video ] Dr Boslough tells us that, in it, we see the ablated meteoritic vapor mixes with the atmosphere to form an opaque fireball with a temperature of thousands of degrees. As it hits the ground, the hot vapor cloud expands to a diameter of 10 km within seconds, remaining in contact with the surface, with velocities of several 100m/s. And at temperatures exceeding the melting temperature of quartz for more than 20 seconds. Moreover, the air speed behind the blast wave exceeds several hundred meters per second during this time. For comparison, an ordinary oxy-acetylene cutting torch in a steel shop uses a thin stream of hot gases at only about 900°C. and 40 psi to cut steel. The speed of that stream of hot gasses is only a little bit more than a stiff breeze. But that's all it takes to turn solid iron into a melted, aerosol, spray. And to blow it away in runnels of melt into heaps of slag. Dr Boslough tells us that: Simulations suggest strong coupling of thermal radiation to the ground, and efficient ablation of the resulting melt by the high-velocity shear flow. We have its existence predicted in peer reviewed literature. But so far I haven't heard anyone attempt to describe the form that such geo-ablative melt might take as it is emplaced. While in motion, any ablated materials from a large, geo-ablative, airburst like that would be in atmospheric suspension, in a density current similar to a pyroclastic flow. And when everything comes to rest, the resulting rock form might be visually indistinguishable from ordinary volcanic tuff, or ignimbrite. If so, we face a conundrum in the Earth sciences. Because it has always been assumed without question that only terrestrial volcanism can melt the rocks of the Earth, or produce 'Tuff'. If very large airbursts can produce formations of geo-ablative melt, instead of craters, then almost every last pebble of airburst melt on this fair world of ours has been mis-defined as volcanogenic. Astronomers Victor Clube, and William Napier, had been talking about the giant comet they described as the progenitor of the Taurid Complex since 1982, in their book The Cosmic Serpent. But no one had connected the dots, and put the Younger Dryas comet, and the Taurid Progenitor together. Except in private, speculative, emails, and letters. And to the best of my knowledge there was nothing in refereed literature. http://dl.dropbox.com/u/2268163/Paleolithic%20extinctions.pdf 7 page Then, in early 2010 Professor Napier published a paper in the Journal Monthly Notices of the Royal Astronomical Society titled, Paleolithic extinctions and the Taurid Complex, -- in it we read: The proposition that an exceptionally large comet has been undergoing disintegration in the inner planetary system goes back over 40 years (Whipple 1967), and the evidence for the hypothesis has accumulated to the point where it seems compelling. Radio and visual meteor data show that the zodiacal cloud is dominated by a broad stream of largely cometary material which incorporates an ancient, dispersed system of related meteor streams. Embedded within this system are significant numbers of large NEOs, including Comet Encke. Replenishment of the zodiacal cloud is sporadic, with the current cloud being substantially over-massive in relation to current sources. The system is most easily understood as due to the injection and continuing disintegration of a comet 50-100 km in diameter. The fragmentation of comets is now recognized as a major route of their disintegration, and this is consistent with the numerous sub-streams and co-moving observed in the Taurid complex. The probable epoch of injection of this large comet, ~20-30 kyr ago, comfortably straddles the 12.9 kyr date of the Younger Dryas Boundary. The hypothesis that terrestrial catastrophes may happen on timescales ~0.1 Myr, due to the Earth running through swarms of debris from disintegrating large comets,

Re: [meteorite-list] SLAGADOCIOUS!
Guido, If there was ever a doubt that you are a true count this newest discovery confirms indeed that you get divine intervention on your hunts. First you find the largest Chondrite ever found in Nevada. Now you find the allusive Cat MT. Pairing. It is my understanding that this is THE FIRST confirmed pairing of Cat MT. The earlier mentioned pecan size example has never been officially verified and therefore likely does not exist. The part about Shirley Wetmore's identification is true. Shirley talked the dude into chipping off a tiny piece and X rayed it and confirmed it was largely made up of forsterite a form of olivine. With this revelation she was able to regain the attention of David Kring who had previously seen the whole rock and was one of many who had previously decided it was slag based on an exterior examination alone. Without Shirley's aid . This rock would likely still be considered slag. I have personally hunted there dozens of times and obviously knew what to look for as I had seen the original Cat MT in person many times before. I shared this very secret ( at the time) find location with the Johnson's and I was with them ( Dave and Jerome) when they each found a separate half of the Snyder Hill find. Dave found the first half on one side of the hill and Jerome found the other half a short time later on the other side of the hill. It seems it had landed on top of the hill , broke into two pieces. One went west and the other east and when found and reunited they fit perfectly back together. Interestingly it too is an L5 but, not an IMB. Could it be from the same fall? Maybe it is based on what we now know about Almahata sitta and how many different types can fall together. Guido, I don't know how you do it but you do it well. Congrats again.

[meteorite-list] Cox's Crater Wrongs
Hi Sterling, Paul - Telling Dennis Cox he has a crater wrong and you get the same response as when you tell some people they have a meteor wrong. When I told Dennis that he needed to study scaling laws over at the Cosmic Tusk, I was treated to a stream of abuse, wherein he claimed that they did not exist, and then later claimed that I had been incapable of applying them before my stroke, as I had no degree in physics. That was followed by a lecture on airbursts, in which he claimed I did not understand them either. When I told Dennis that his features were not likely they were from the YD event, I got with more of the same. When I told Dennis that the features he was seeing via Google earth had to be checked out on the ground, he repeatedly called me a liar for stating that Dave Morrison supported Muller's Nemesis Hypothesis (and David naturally encourage him in this - a number of you here know how that goes. Me, I'm still waiting for Morrison to publicly simply state that the Nemesis Hypothesis is wrong.) And then Dennis compared my work to Velikovsky's, the ultimate insult. Cox does not realize that Velikovsky was simply an E.P. wannabe. Dennis clearly does not understand the difference that the Earth's atmosphere makes in impact processes. I tried to point Dennis towards the upcoming Meteor Crater field school, but it appears that he would rather continue to vent his frustrations. Paul, Sterling, keep it up. :P) E.P.

Re: [meteorite-list] vast geoablation in Argentina, craters from SW to NE -- Cox re Boslough bursts: Rich Murray 2011.07.31
While no one is going to address all of these points from this long post, I'll tackle one --- the Libyan Desert Glass: Low Altitude Airburst... from a ~100 meter diameter NEO melted sand into glass across a region about 10 km in diameter during Libyan Desert Glass impact... 35 million years ago. The problem is that when walks the incredible inferno of this part of the Sahara and its vast sands, one thinks: how could this sand have been fused in glass? And that is a DEAD WRONG question. 35 to 28 million years ago this area, and tens of thousands of square miles around it, were UNDERWATER. These low desert basins were a lacrustine environment -- shallow waters, with an occasional patch of swampy ground (on what are now hilltops). When I say shallow, I mean 100 meters more or less. Underlying the LDG area is sandstone, the upper layers of which is younger than the LDG, sandstone that formed at those lake bottoms. The LDG is found along the former shoreline in one area of the SW shore of the Depression. There's a nice Google map of those lacrustine basins at: http://www.inognidove.it/egypt/ If the LDG formed from dry desert sand by incredible heat from an airburst or an impact, it had to have happened somewhere else and the LDG was moved here, or they are yellow tektites from the same event as other tektites their age or another event of similar age elsewhere. If the Belize tektites are australites in age, they were tossed a long way. The LDG could have been tossed from Chesapeake Bay, which BTW was a lot closer to Egypt in the Oligocene than it is now, as the Atlantic was narrower, not that great distances matter much to tektites. I would give a bunch of references, but since I've posted about this twice over the last ten years and put lots of citations in them, just check the List Archives if you want references. Here's one, though. The 1981 expedition... established that the present mass of glass exceeds 14,000,000 tons; the original mass of glass may have been 10,000 times greater, or 140,000,000,000 tons. [units converted] http://www.sciencedirect.com/science/article/pii/0022309384901777 140 billion tons of glass is one heck of a lot of glass for one little 100-meter NEO to whip up a batch of. Let's see. First you have to boil 10-100 meters of water off, then dry out the wet bottoms and all the sand, then you have to melt 140,000,000,000 tons of it. I think you need a bigger bang... even to toss it there. Sterling K.

[ http://www.space.com/2295-supercomputer-takes-cosmic-threat.html ] The colors in the simulation we see in the below video, are graded by temperature.

[ 21 second video ] Dr Boslough tells us that, in it, we see the ablated meteoritic vapor mixes with the atmosphere to form an opaque fireball with a temperature of thousands of degrees. As it hits the ground, the hot vapor cloud expands to a diameter of 10 km within seconds, remaining in contact with the surface, with velocities of several 100m/s. And at temperatures exceeding the melting temperature of quartz for more than 20 seconds. Moreover, the air speed behind the blast wave exceeds several hundred meters per second during this time. For comparison, an ordinary oxy-acetylene cutting torch in a steel shop uses a thin stream of hot gases at only about 900°C. and 40 psi to cut steel. The speed of that stream of hot gasses is only a little bit more than a stiff breeze. But that's all it takes to turn solid iron into a melted, aerosol, spray. And to blow it away in runnels of melt into heaps of slag. Dr Boslough tells us that: Simulations suggest strong coupling of thermal radiation to the ground, and efficient ablation of the

Hallo Horst. Nutzen Sie die Google Translate-Funktion? Ich bin sicher, es wird eine Menge helfen, wenn Sie Probleme beim Schreiben in englischer Sprache zu haben. Ich bin sicher, Sie können dies zu verstehen, und ich nutzte die translate-Funktion. Willkommen auf der IMCA! Eigentlich habe ich gerade festgestellt, dass Sie aus Österreich sind. Hoffe ihr könnt noch lesen diese aber. Hello Horst. Do you use the Google translate feature? I am sure it will help a lot, if you have trouble writing in English. I am sure you can understand this, and I used the translate function. Welcome to the IMCA! Actually I just realized that you are from Austria. Hope you can still read this though.

My name is Horst Wagner and I live in Lower Austria. Since seven months, I am a member of IMCA .Member#9404. Because my English is very bad, I have not yet found the courage to present myself to the list. The two new members, Craig and Rachid, and the last mail from Mrs. Anne Black animated me to act. For more than seven years I collect meteorites. In primarily from Northwest Afrika. My collection includes hundreds of different classification meteorites and purchased almost exclusively for IMCA members.CV,CO and HED meteorites and other achondrites are my primary focus. Since a couple of years I serch also tektites (Moldavite) and Stones and Glas from the Ries impact in Germany. My profile in the members list will be created soon. I thank the new members, and Adam Hupe and Mirco Graul and especially to Mrs. Anne Black, who is president of the IMCA provides outstanding.

Hello List. I have a Campo del Ceilo end cut, with a small white inclusion ( 1mm) that looks like a chondrule. As far as I know, silicated Campos have black silicates, and there are no other visible inclusions in my piece. As soon as I find a place to store photos, I will post a pic, or it can be seen in Facebook in the Meteorites group. Any thoughts would be helpful.
