Re: [meteorite-list] Chondrule formation mechanism (Info Please)
The date measured is almost certainly the formation date. My undertanding is that there are gaseous isotopes of daughter products which are used for ageing. When the rock/chondrule melts, it allows the gases to escape and this has the effect of resetting the clock. This is how we know that the rocks from the LPBE are 3.9bn ya. Chondrules, by the same method demonstrate an age in excess of 4.5bn ya. The likelyhood of many atoms of similar type being in the same region of space is likely high. I've never studied the theories of what happens in a supernova but the energies which synthesise all the elements greater than 32(iron) would, I believe create large numbers of these elements in the same region which then gets dispersed into interstellar space, from which proto stars and planetessimals coalesce (bad spelling). It's fascinating stuff and I'm sure nobody understands it properly. Rob McC --- E.P. Grondine [EMAIL PROTECTED] wrote: Hi Sterling, I did not post my reply to you to the list, so they won't know what the extracts you cited came from - if you have a copy of that message please post it - The problem still remains what caused sufficient number of atoms of the same type to be in the same place at the same time to produce the crystals and glasses observed. If you have the gravity of a source proto-planet differentiating the components in an immiscible melt, then that problem is solved. I can't see any differentiating mechanism for an instellar melt, regardless of energy source. No doubt the dating techniques are accurate. And no doubt the elements were frozen in time in the chondrule glasses and crystals. But is what is being dated, the elements' formation date, or the chondrule's formation date? good hunting, Ed --- Sterling K. Webb [EMAIL PROTECTED] wrote: Hi, Ed, ...but does this mean that the formation of the condrules and their matrices date to that time? The formation date is when all the various materials can no longer be mixed with other material, be wetted, dried, migrate, be modified, interact chemically, be altered, or otherwise be messed with. The tiny packet of the chondrule is melted, fused, sealed -- ain't nothing going nowhere. From that point, the isotopes decay without any material being allowed to escape. The uranium turns slowly to a peculiar isotope of lead with a long halflife (billions of years). You count the uranium atoms; you count the odd lead atoms; calculate how long it took for some of the original uranium to that number of lead atoms. Since nothing can enter or leave the chondrule, it's pretty accurate (very accurate). No doubt the constituent components of our solar system date to that time, but does this mean that the formation of the condrules and their matrices date to that time? A solid rock, a melted lump (like a chondrule), a piece of glass (like a tektite) are all good dating candidates because atoms can't go waltzing in and out like it was a border bordello... Once a rock or any lump shows signs of being altered by the environment, partial melting or heating, aqueous modification, alarm flags go up. Sometimes, it's a good thing: a tektite's K/Ar date turns out to be when it either impacted or was impacted, but it's Rb/Sr shows (I think) its original formation date (curiously, about 480 mya). Many wouldn't agree with that, but they then have to explain why its original Rb/Sr ratio is radically different from ANY other rock, on Earth or off. (Mostly that detail's ignored.) At any rate, it's different from its K/Ar date (each tektite type has its own K/Ar date). If the dates are right, the problem becomes how did that many identical atoms get together in one place so that the chondrules could form? Not sure what you mean here. The chondrules have many elements in many compounds, just like the meteorites, many of the same ones. They were gas and dust before being flash melted, typical of the inner solar nebula -- the usual crap. Lots of argument about what melted them, and the details, of course, solar flare, electric currents in the disc, magnetic effects, shock waves? Your theory of pressure release isn't necessarily dead. What if a sudden short heating event (solar flare for example) melts them radiatively and heats the gas around that region. After the chondrule is flash fried, the hot gas (no longer being heated) expands rapidly and the heat and pressure around the chondrule drops as the gas expands and cools, letting them cool quickly by radiating their heat away quickly (?). I should shut up; that's dangerously close to being chemistry... Sterling --- My favorite two books on the formation of the solar system

Other systems of isotope measurements (like 147Sm/143Nd) give 4.553 +/- 0.003, and so forth. Within the limits of measurement, all chondrites are the same age, a hair younger than the solar system itself, the Class of Zero, and so are their chondrules. Meteorites that do not (never did) contain chondrules have varying ages. Lunaites are the age of that portion of the lunar crust they came from, generally quite old compared to Martians which have the formation age of the basalt flow they were chipped off of for the long haul to Earth. Irons, which formed inside a differentiating body, have younger ages; some very much younger if the differentiation took a long time (Weekeroo Station IIe is 4.340 Gya, Kodaikanal IIe 3.800 Gya, many IAB irons the same). I'm thinking that before you need to develop a theory to explain a 3.9 Gya chondrule, you'd have to actually have a 3.9 Gya chondrule.

Oddly, if you Google for oldest chondrule, you get the oldest chondrules, and if you Google for youngest chondrule, you get the oldest chondrules... on the grounds that it is young as the solar system.

--- E.P. Grondine [EMAIL PROTECTED] wrote: Hi Rob - molecules of a feather flock together? why? This is the most blatant speculation on my part and I have not looked it up to check this (though to be fair, I didn't make the comment above, I just like it) but this is what I think and no more... Supernova are responsible for the synthesis of all the heavier elements. I suspect that large quantities of single elements are likely to be formed at the same place in the catastrophic destruction. I base this soley on the shell model of Supergiant stars and that the explosion is likely to apply the same temperature and energy to these regions making it likely that many fusion events in one place produce the same daughter element. These will inevitably spread in the explosion but are still going to travel in similar directions. This is obviously an off the cuff description and I've probably no justification for suggesting they head off in the same direction into space. This debris will eventually come together to form a protodisk. I am not sure that it is necessarily the case that elements or molecules of a feather -as it was put- may necessarily flock together. How homogenous the disk is I don't know but I cannot see any reason why it shouldn't be. Jupiter is essentially the same composition as the sun, after all but the sun also contains all the same elements as the earth, as observed spectrally. The structure of gas giants have rocky interiors and probably similar to terrestrial planets bulk composition. What it may be is that the minerals/elements which formed the chondrules condensed first. I believe this is what is currently believed. This being the case, it makes sense that they are mostly made of similar stuff as this is all there was to make them. I appreciate that different chondrules have different minerals, even in the same meteorite. I suppose this is where your question is most valid, why did they group together like that and why aren't they all a general mish-mash of all the available minerals? I suppose an answer to this is the chondrules may have initially formed at different distances. They can come together to form parent bodies interspersed by matrix at a later period. We've seen on this list in the last few months that planetary orbits are not nearly as fixed as we tend to think (the dancing rings video of the inner solar system and Neptune's migration spring immediately to mind). My difficulty with this is why would minerals form at different distances? Under gravity they'd all fall inward at the same rate during the earliest period of the disk formation. I need to have a bit of a think about it. It may be due to temperature in the protdisk at different distances. Not convinced I can bull my answer to that. Another contentious rambling I have is that the reason for the clumping of similar molecules is normal. If you think how crystals form in liquids, you need a nucleation point but once you begin to build up a structure there is a tendency for them to stick to their own type. This is true for liquid drops as well. I don't know if this is Van der Waal's forces or something else. VdW is a tiny force as I recal but in a low density environmet with a few thousand years, it may be enough. Dunno. I hope to one day have the mathematical ability and the time to work this out before someone else does...If only to prove I'm wrong. Sorry for the lengthy mail.

David Everything is possible, but I think that You should add one more 0 NWA 267 also cost around 50$ on begining (I dont remember) and last week I sold my coin for 400$. One other seller offered his coins for 500$ last few months on eBay. Im sure they are all gone. I have some interesting talks with person who sell coins and from who I bough my Nantan coins. He was more than surprized what is going on with this Meteorite coins. Becouse he have more pre-orders for Nantan coin as for any other coin. Also soin with NWA267 show on market it sells much faster than any other coins in the same time. There is 2.5 times more Nantan coins than NWA267 but its also not much. In a few months this could be hard to buy for start price. -[ MARCIN CIMALA ]-[ I.M.C.A.#3667 ]- http://www.Meteoryt.net [EMAIL PROTECTED] http://www.PolandMET.com [EMAIL PROTECTED] http://www.Gao-Guenie.com GSM +48(607)535 195 [ Member of Polish Meteoritical Society ] __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
RE: [meteorite-list] Second Meteorite Coin with Nantan
Hello Marcin, Thanks for your e-mail. On this coin I was involved more in the process (then in the 1st coin) and tried to get them to use a different meteorite, but it looks like it came out looking pretty nice. (In fact I was paid as an advisor this time as well as supplied the material for the coin.) I have yet to get mine so can you tell me if my name/signature appears on the COA as it did last time?

Re: [meteorite-list] The Origin of Chondrules and Chondrites - Part 1 of 3
Thought this older email on the subject from Bernd might be interesting to some. It's one of those few files I save. P.S. I took the advice and purchased it but I'm still baffled or is it befuddled?! Jerry Flaherty - Original Message - From: [EMAIL PROTECTED] To: [EMAIL PROTECTED]; Meteorite-list@meteoritecentral.com Sent: Saturday, March 04, 2006 2:24 PM Subject: [meteorite-list] The Origin of Chondrules and Chondrites - Part 1 of 3 Guten Abend Stefan, Hello List, I'm considering to buy: The Origin of Chondrules and Chondrites by Derek Sears, any recommendation? Book Review: MAPS 40-4, 2005 April, pp. 655-656: The origin of chondrules and chondrites, by Derek Sears. Cambridge University Press, 2004, 209 pp. $110.00, hardcover (ISBN 0-521-83603-4). Few would disagree with Derek Sears' claim that chondrites are the most studied rocks in the solar system and the least understood. To help remedy this, Sears has written a monograph, which is profusely illustrated with black-and--white images, diagrams, and sketches, that reviews the properties and proposed origins of chondrules and chondrites. He carefully guides the reader through the wealth of chemical and isotopic data on chondrules and chondrites, provides an excellent account of the theories of chondrule origins, and offers a coherent, though very controversial, model for their origin. The first two chapters provide a historical overview of chondrite research and classification and a concise guide to the asteroids, their role as meteorite parent bodies, and the effects of impacts in forming regolith and impact melts. This is followed by a brief review of the chemical and oxygen isotopic compositions of the various groups of chondrites and their ages. Sears then identifies what he considers to be the most important questions about chondrites: how did the chondrules form and how were Fe,Ni metal and silicate fractionated from one another? The last half of the book focuses on the chemical, physical, and isotopic properties of chondrules that bear on these two questions and the various mechanisms that have been proposed to form chondrules.

On Tue, 24 Oct 2006 19:53:34 -0500, you wrote: Could the bright white chondrule in same quadrant be a CAI? Could the zoned, multicolored eggish- shaped one be a clast of another chondrite? Or do chondrules just look like a miniature meteorite once in a while? In complete ignorance, I ask. http://webpages.charter.net/garrison6328/tmp/cool_unclassified.jpg I wish I knew the answer to lots of questions about this piece (and about more or less any other meteorite) but raw mineralology is one of my weakest areas. About all that I can handle in identifying mineral species in meteorites is this looks cool and that looks odd. It seems pretty obvious, though, that this has a pretty darned low metamorphic grade, and that the chondrules (and possibly inclusions deserving other names) have had a pretty complex and diverse history. There is NO visible metal in it, but there are areas where it is apparent that metal has oxidized away. That could be from long terrestrial weathering, or it could be ancient, I don't know. The redness of the matrix does resemble some R chondrites to me. I've made a map of some of the features that interest me: http://webpages.charter.net/garrison6328/tmp/cu_map.jpg the zoned, multicolored one I mentioned is number 2, of course. It is a similar size to other chondrules in the piece, so I don't know about the alien clast thing-- unless it came from something with much smaller chondrules. As for the possible CAI, you mean in number 3? I donno. It has white areas and also blueish ones and reddish ones.

[meteorite-list] Re: Weird bit-o-space The Rules of Chondrule colors
As to identifying minerals through photographs let me mention... this is why God created thin sections and polarizing microscopesand as man came to better understanding the micro probe was given unto him(Grin) There are no CAI's that I see in this specimen. Someone has some great CAI photos from Allende once posted to the list. As a rule of thumb: (statistically speaking): Light colored chondrules with be feldspatic aka feldspars. The potassium sodium calcium aluminum silicates(tectosilicates). Examples Orthoclase (KAlSi3O8), e.g Albite (NaAlSi3O8) and Anorthite (CaAl2Si2O8. Terrestrial felspars come in paractically all colors especially white,cream, pink,green as in microcline, blue and with shilleren as in Labadorite. Black probably amphibole. (Dark--less than black/bronze/gray/deep brown are pyroxene or olivine aka Magnesium Iron Silicates who's silicon bonding varies based on the amount of oxygen in the source mix. If there is sufficient oxygen the silicate tends to for a tetrahedron of 4 oxygens and one silicon. Olivine is a nesosilicate where single tetrahedrons orient in one of 2-3 preferred patterns. Pyroxenes and amphiboles are the inosilicates; single chain silicates (pyroxenes) and double chain silicates available)link in long molecules to satisfy the shortage of oxygen. These form when oxygen is in a lesser proportion and the molecules have to double up on the bonds. (e.g enstatie, augite, aegirine,bronzite). Caution: Metallic Iron and Troilte can look gray or bronze. (For perspective Mica is a phylosilicate or sheet silicate which bonds only in two planes ergo it is easily peeled off in sheets) As per the map #5 and possibly #6 look like pyroxenes/olivine #5 being a barred chondrule. Northwest of #5 is an interesting non spherical chondrule-looking critter. #4 could be one of the cryptocrystilline( fiberous pyroxine/amphibole chondrules described in the Wikipedia article below. http://en.wikipedia.org/wiki/Chondrule There are also pyroxinoids( inosilicate-like minerals with calcium or phosphorous,etc) which distort normal crystal growth which tend to kink and fold back on themselves. A description of silicate lattices for the diehards: http://ccp14.minerals.csiro.au/ccp/web-mirrors/xtaldraw/crystal/silicate.htm One suggestion for future some scale item in the photo for reference.

Re: [meteorite-list] Wow. Look what I just stumbled across!
Hi, In this section, you will find references to the hydroplate theory. You really should back up to the table of contents and investigate the hydroplate theory, which maintains that there is (or was) a vast subterranean ocean 10 miles deep under the crust, a kilometer thick chamber, mounted on pillars, surrounding the Earth and filled with an ocean. This is a delightful throwback! And when I say throwback, I mean 'way back. This is the abyssmal ocean of ancient myth. The Sumerian word for it was apsu or absu from which the word abyss derives (the only word in English with a Sumerian root). But the concept was already old at the time of the earliest Sumerian culture and can be traced in Ubaid pottery motifs back to 5300 BC. (This dating would make the myth older than the world in this fellow's cosmology!) The mythological apsû was freshwater: lakes, springs, rivers, wells, and other sources of fresh water were thought to draw their water from the apsû. The Sumerian god Enki (Ea in Akkadian) was believed to have lived in the apsû since before human beings were created. His wife Damgalnuna, his mother Nammu, and a variety of creatures also lived in the apsû. In the city Eridu (predating the Sumericans, an Ubaid city), Enki's temple was known as E-abzu (the abzu temple) and was located at the edge of a swamp, an apsû. Certain tanks of holy water in Babylonian and Assyrian temple courtyards were also called apsû or abzu. Of course, it's nicely dressed up in scientific gobble- dity-gook about supercritical water; I do like a good myth-maker! The Great Fountains of the Deep make the ocean trenches, mid-ocean ridges, all strata, all limestone, blow all the comets and asteroids and meteorites off the face of the Earth. The Sumerians would be delighted at how durable their myth is! One might suppose the author of this fantasy to be superficially self-educated, but he is a Ph.D. from MIT, has taught college courses in physics, mathematics, and computer science, is a retired full colonel (Air Force), West Point graduate, and former Army ranger and paratrooper, former Director of Benet Research, Development, and Engineering Laboratories in Albany, New York; tenured associate professor at the U.S. Air Force Academy; and Chief of Science and Technology Studies at the Air War College (he says), and only found his way into this particular pocket universe after retirement. (My taxes are contributing to the military pension that supprts him while he does this nonsense. I should be miffed or ask for my two cents back.) The really fascinating thing is that he saves the Biblical creation and chronology by resort to an ancient mythos not found in the Bible, one which the Biblical authors would (and did) regard as thoroughly beyond the pale. They would have smote him down as an Assyrian apologist... (The Sumerians being long forgotten by the time the Bible was written.) But this is a durable myth; it creeps back into the cosmology of Cosmas Indicopleustes: http://ccat.sas.upenn.edu/awiesner/cosmas.html although Dr. Brown leaves out the square corners of the Earth and the pillars that hold up the Heavens (careless of him).
