Re: [meteorite-list] xenolith vs. polymict breccia?
Walter Branch [EMAIL PROTECTED] wrote: Hi Yes the term xenolith would apply to the individual clast. It is a term used to describe something foreign or exotic that really shoulnd't be there. If the clast was the same as the matrix I would hesitate to use it but if it were different then it seems like a good term. Igneous rocks can certainly have xenolithic clasts of other igneous rocks, sedimentary rocks and metemorphic rocks. As an intrusion forces its way through country rock it will often pick up such clasts. If individual crystals are picked up which do not belong to that melt, but to another, these are termed xenocrysts. I would struggle to envisage chondrites being caught up in an igneous melt on an asteroid though. This would surely imply only partial melting of the body. If the two were found together it would surely be in a breccia and the chondritic component wouldn't be encased in the igneous component. A rubble pile could certainly have igneous clasts such as eucritic fragments in an LL body for instance. Aubrey Hi Aubry, Thanks very much for your comments. Yes, I was considering rocks with a matrix. I must admit, I had not thought of rocks without a matrix - clast supported vs. matrix supported. That is a very interesting distinction.Now I have yet another term with which I can try to impress my wife (not an easy thing to do after 17 years of marriage:-) Would the term xenolith apply to the individual clasts in a polymict breccia? Could an igneous rock have axenolithic clast of non-igneous material or could a sedimentary (e.g., rubble pile) type host have an igneous clast, thus making bothpolymict breccias? I suppose given enough collisions among asteroids, any combination is possible (e.g., chondritic monomict breccia's with exoctic igneous clasts). Perhaps in descriptions of meteorites the terms polymict xenolithic breccia and monomict xenolithic breccia should be used as oppose to just xenolithic breccia which to me does not distinguish whether the clasts are the same or not. It merely says that at least some of the clasts are different to the matrix. Yes, as you have described it, this makes sense. Aubry (and everyone) I have received an email from a recently former list member who reports that there is a paper which describes formal guidelines on the description xenolithic inclusions in meteorites: Binns R.A. (1968) Cognate xenoliths in chondritic meteorites: Examples in Mezö-Madaras and Ghubara (GCA 32, 299-317). Hope this helps.

Hi Sorry for the length of this reply. Got carried away! Go to bottom 3 paragraphs for summary. You are right.A polymict breccia descibes a sedimentary rock made up of angluar clasts of different rock whilst a monomict breccia refers to a sedimentary rock made up of angular clasts of the same rock. A brecciacan be clast supported (the clasts are touching) or matrix supported (clasts are not touching). If clast supported, a matrix may or may not be present. The term xenolith refers to a foreign rock or clast incorporated into another rock. Traditionally I would tend to only use this term when refering to igneous rocks but it could be used for exotic clasts in sedimentary rocks (and chondrites). Ghubara is an example,being classified as a xenolithic chondrite. If using the term xenolith you are probably implying a matrix is present. The matrix is local, in the case of chondrites, and the xenolith not local - it came from elsewhere. If you were to apply the term xenolith to a matrix free polymict breccia the xenolith would simply have to be the less abundant type of clast. This is not satisfactory as just because it is less abundant does not neccessarily make it the 'foreign' bit. This is my understanding of rock names: Angular clast of same composition, no matrix = monomict clast supported breccia Angular clasts of different composition, no matrix = polymict clast supported breccia Angular clasts of same composition with matrix also of same composition = monomict clast or matrix supported breccia Angular clasts of same composition in a matrix of different composition = monomict clast or matrix supported brecciaor xenolithic chondrite. Angular clasts of different compositions in a matrix = polymict clast or matrix supported breccia or xenolithic chondrite ( but if the matrix is the same as some of the clasts the term xenolith would only apply to the different composition clasts) So, to summarise, in my opinion a monomict or polymict breccia can be the same thing as a xenolithic chondrite. Xenolithic simply implies some or all the clasts are different to the matrix of the rock. The terms polymict and monomict do not consider the matrix. Perhaps in

NEWS RELEASE: 2004-035January 25, 2004 NASA HEARS FROM OPPORTUNITY ROVER ON MARS NASA's second Mars Exploration Rover successfully sent signals to Earth during its bouncy landing and after it came to rest on one of the three side petals of its four-sided lander. Mission engineers at NASA's Jet Propulsion Laboratory, Pasadena, Calif., received the first signal from Opportunity on the ground at 9:05 p.m. Pacific Standard Time Saturday via the NASA Deep Space Network, which was listening with antennas in California and Australia. We're on Mars, everybody! JPL's Rob Manning, manager for development of the landing system, announced to the cheering flight team. NASA Administrator Sean O'Keefe said at a subsequent press briefing, This was a tremendous testament to how NASA, when really focused on an objective, can put every ounce of effort, energy, emotion and talent to an important task. This team is the best in the world, no doubt about it. Opportunity landed in a region called Meridiani Planum, halfway around the planet from the Gusev Crater site where its twin rover, Spirit, landed three weeks ago. Earlier today, mission managers reported progress in understanding and dealing with communications and computer problems on Spirit. In the last 48 hours, we've been on a roller coaster, said Dr. Ed Weiler, NASA associate administrator for space science. We resurrected one rover and saw the birth of another. JPL's Pete Theisinger, project manager for the rovers, said, We are two for two. Here we are tonight with Spirit on a path to recovery and with Opportunity on Mars. By initial estimates, Opportunity landed about 24 kilometers (15 miles) down range from the center of the target landing area. That is well within an outcropping of a mineral called gray hematite, which usually forms in the presence of water. We're going to have a good place to do science, said JPL's Richard Cook, deputy project manager for the rovers. Once it pushed itself upright by opening the petals of the lander, Opportunity was expected to be facing east. The main task for both rovers in coming months is to explore the areas around their landing sites for evidence in rocks and soils about whether those areas ever had environments that were watery and possibly suitable for sustaining life.

[meteorite-list] A few things that may be of interest
Dear List Members, First of all, congratulations to NASA who has had its hands full managing several missions at once for the successful landing of Opportunity. That outcrop of bedrock image sure looks enticing, can hardly wait for some high resolution images of it! I could imagine walking over there and chipping of some samples with a geology hammer. I guess Opportunity will have to serve as eyes for us stuck here on Earth. I will hazard a guess just for fun and assume this outcrop is volcanic but will be floored if it is sedimentary deposited by water. The second thing is a little bit of mischief we were engaged in. We recently posted three images of rocks the other day for fun. As some of you have already surmised the third image is not of a meteorite. It is a beautiful breccia that I found three years ago while searching for meteorites in some glacial till. Since there is a dealer who always claims to have the same material we do after we announce something we figured we would throw out some bait. He half swallowed the hook and said he thinks he has some of this lunar material and asked where we found it. Unless he has been to Washington State, USA, 20 miles from my house he is not telling the truth. The funny thing is we even said in the posting that it was a US find. A few other List members were engaged in this experiment. This demonstrates that the vast majority of List members know what they are talking about when identifying meteorites as we received several emails asking about its meteoritic status. We never claimed it was a meteorite to begin with and it goes to show that some will go to any length to be competitive. The final thing is that we changed the date of the Wilcox Dry Lake hunt to Sunday the 8th because most of you will not be in Tucson until that weekend and the Pitt auction has been canceled. It also rained there recently so we want to give it a few more days to dry out. The good thing is that rain sometimes washes out meteoritic material making it much easier to find. We are all meeting in front of the Reeds room (Rm. 110 at the Vagabond Inn) at 9:30 am that Sunday. Wilcox is about a one hour drive from Tucson. Bring yourselves, a good magnet, some bellywash and lunch. We will bring some coolers and a barbecue. Over a dozen List members have expressed an interest in going so it should be a heck of a lot of fun, everybody will be welcomed. We will make a few more announcements soon so stay tuned.

[meteorite-list] Opportunity Sits in a Small Crater, Near a Bigger One
Guy Webster (818) 354-5011 Jet Propulsion Laboratory, Pasadena, Calif. Donald Savage (202) 358-1547 NASA Headquarters, Washington, D.C. News Release: 2004-037January 25, 2004 Opportunity Sits in a Small Crater, Near a Bigger One A small impact crater on Mars is the new home for NASA's Opportunity rover, and a larger crater lies nearby. Scientists value such crater locations as a way to see what's beneath the surface without needing to dig. Encouraging developments continued for Opportunity's twin, Spirit, too. Engineers have determined that Spirit's flash memory hardware is functional, strengthening a theory that Spirit's main problem is in software that controls file management of the memory. I think we've got a patient that's well on the way to recovery, said Mars Exploration Rover Project Manager Pete Theisinger at NASA's Jet Propulsion Laboratory, Pasadena, Calif. Opportunity returned the first pictures of its landing site early today, about four hours after reaching Mars. The pictures indicate that the spacecraft sits in a shallow crater about 20 meters (66 feet) across. We have scored a 300-million mile interplanetary hole in one, said Dr. Steve Squyres of Cornell University, Ithaca, N.Y., principal investigator for the science instruments on both rovers. NASA selected Opportunity's general landing area within a region called Meridiani Planum because of extensive deposits of a mineral called crystalline hematite, which usually forms in the presence of liquid water. Scientists had hoped for a specific landing site where they could examine both the surface layer that's rich in hematite and an underlying geological feature of light-colored layered rock. The small crater appears to have exposures of both, with soil that could be the hematite unit and an exposed outcropping of the lighter rock layer. If it got any better, I couldn't stand it, said Dr. Doug Ming, rover science team member from NASA Johnson Space Center, Houston. With the instruments on the rover and just the rocks and soil within the small crater, Opportunity should be allow scientists to determine which of several theories about the region's past environment is right, he said. Those theories include that the hematite may have formed in a long-lasting lake or in a volcanic environment. An even bigger crater, which could provide access to deeper layers for more clues to the past, lies nearby. Images taken by a camera on the bottom of the lander during Opportunity's final descent show a crater about 150 meters (about 500 feet) across likely to be within about one kilometer or half mile of the landing site, said Dr. Andrew Johnson of JPL. He is an engineer for the descent imaging system that calculated the spacecraft's horizontal motion during its final seconds of flight. The system determined that sideways motion was small, so Opportunity's computer decided not to fire the lateral rockets carried specifically for slowing that motion. Squyres presented an outline for Opportunity's potential activities in coming weeks and months. After driving off the lander, the rover will first examine the soil right next to the lander, then drive to the outcrop of layered-looking rocks and spend considerable time examining it. Then the rover may climb out of the small crater, take a look around, and head for the bigger crater. But first, Opportunity will spend more than a week -- perhaps two -- getting ready to drive off the lander, if all goes well. Engineering data from Opportunity returned in relays via NASA's Mars Odyssey orbiter early this morning and at midday indicate the spacecraft is in excellent health, said JPL's Arthur Amador, mission manager. The rover will try its first direct-to-Earth communications this evening. The main task for both rovers in coming months is to explore the areas around their landing sites for evidence in rocks and soils about whether those areas ever had environments that were watery and possibly suitable for sustaining life.

Hi everyone, I attended a special party at the LPL at the Universityof Arizona tonight. We were linked up live with JPL and watched the entire landing sequence live. It was great. I am still in awe that people can send a machine 100 million miles away, send it at 12,000 miles per hour burning like a meteor, and land it safely. It is on one side, so the rover is not upright like Spirit was, so it will take a little longer to get the petals open, but not a problem. People could learn alot from NASA, and I hate to listen to whiners until they can show proof that it can be done better than NASA has done. WAY TO GO JPL, NASA, and all who are working on these landers. Another great day for the USA space program. Mike Farmer OH yeah, Dr David Kring showed NWA 998 to all the people, nice to look at a piece of Mars while a machine was burning through it's atmosphere. Gave me chills.

[meteorite-list] Thin Section Photo's / Tucson
Hello Folks, It's been quite a while since I've posted, I guess it's time to step up to the plate! I wanted to let you all know that my brother Rich and I will be participating in the Tucson Show again this year. I'll be there from Jan 30 until Feb. 8th. My brother is going to be there through the 14th of Feb. We will have our 451 gram (originally 638 gram) Park Forest on display and for sale. It can be seen on page 25 of the July 2003 issue of "Sky and Telescope" magazine, and it is center stage on the "Park Forest Meteorite" poster made by the Tomaselli's, which is available in "Meteorite" magazine. I am going to include it in Michael Bloods auction if I haven't waited too long. We'll also have a few other meteorites for sale as well. You won't find us in the meteorite corridor however, as that is not what we are really there for. We can be found at the "La Quinta Inn" ( formerly the Holiday Inn Express) room 133, at I-10 and Starr Pass Blvd. To visit us you must pass over to the other side so to speak, and visit the metaphysical hotel! How we ended up there is a long story, but it is a meteorite hunting story. A meteorite hunting story gone awry! Some of you know about us, some know the story, but for the rest, in a nut shell; After about 30+ authentic meteorite finds, and several years of small time collecting and endless museum visits, I followed up on a great meteorite lead. Sept. 9, 2001, I went to a 5 acre farm where I was told a witnessed fall, and recovery had occurred a long time ago. The rock was kept in the house for a number of years and later lost after the old folks passed on. Within about an hour and a half of hunting I recovered a stone that fit the bill, setting under an old apple tree next to where the old house had once stood many years ago. It was dark, strongly attracted to a magnet, and when I struck it with a file, bright shiny metal was visible in a dark green, stone matrix. Of course all the hairs on my body stood straight on end! I quickly guessed the stone at 20 + pounds ... wow! Then we joined the circus... I mean, then we began trying to have the stone identified. This is no easy feat for a common electrician and a carpet installer let me tell you! Since all my previous finds were already known falls I had no experience in classification procedures, (and apparently still don't). We started at our local institute where the geologist is an acquaintance of mine. He decided we should take it up to Michigan State so we did. The Dr. there gave me a phone # to a Dr. at Purdue, where I later had the privilege to meet some outstanding Dr.'s in the field, like Brother Guy! What an honor.. anyway, they decided it needed to go to the US Dept. of Energy for Al 26 testing, at the same time we had mailed a small specimen to the Smithsonian in DC It disappeared at the post office due to Anthrax, it was incinerated! The U. S. D. O. E. came back with a heartbreaking conclusion, the good Dr. said that he was so certain it was a meteorite that he tested it for 100 times less Al-26 than he would expect to find in a normal meteorite, and mine had none. "Therefore it is not a meteorite." When I asked him what it was he said he "had no idea," "but there are a few places on Earth where nickel iron bearing rocks can be found." I later found evidence to suggest that a stone high in Mg is not suitable for the Al-26 analyses, this one is 6% Mg, possibly too high for an accurate conclusion. I later had it argon dated at Univ. of Michigan. It was determined to be 45 ma if terrestrial, 75 ma if extra terrestrial. The Dr. that did the test was confounded, he expected it to be 4.5 billion, or less than 100 years if an artifact. He didn't think for a minute it could be an Earth rock. Let's call this Part One, I'll tell some more of the story soon. It will be fun, complete with a lying, stealing dealer, disappearing specimens, suspicious goings on at some prominent establishments, The Elusive Thin Section, all sorts of good stuff. See, this is no ordinary chondrite, it's not ordinary anything! It doesn't match any known rock, terrestrial or otherwise. I have tried to prove that it is slag, I have tried to prove that it is terrestrial, and I have tried to prove that it is a meteorite, and I have had no luck with any of them. This thing has been looked at by many experts and remains nameless. I am not 100% sure what it is. I would give nearly anything to have it written up and classified as something. The reason we are at the La Quinta Inn is because of the Cr spinel crystals that reside inside the stone. They are little pyramids with a sphere locked in the framework of the crystals. The crystal people think they are special, and who am I to argue? When you see them you will understand. After more than two years of research I haven't yet found a single mention of this crystal form anywhere. Apparently it is in this one stone only, hard to believe. Considering the circumstances by which I came into
