so why is there carbonacious  shale  in  somer  meteorites?

Well, first I probably should know what a somer meteorite is, right? But you wanted answers, not more questions, right? Sorry, again. Okay, but be warned that a renowned physics professor at the University of Texas, a Dr. Steven Wienberg, I think (I hope!) it was, once reamarked about how remarkable it seems that our questions always honestly generate far more new questions than answers, so I'm not completely out of line, here, contrary to what may be quite conventionally viewed as popular opinion, especially in this context, i.e. an experimental situation, to wit; Yahoo! ANSWERS, a beta program.\nI believe Dr. Weinberg was involved somewhat in chaos theory, among other quite facinating things, I'm sure.\nIf memory serves me right, the term "carbonaceous" refers to, specifically, a geological era or period characteristic in reference to the more general use of the term as being rich in carbon, or consisting of carbon. Given carbon to be often associated with our familiar forms of DNA-based life, if it can be reasonably and plausibly demonstrated that any significant quantity or quality of carbon was introduced into the terrestrial environment via space, then this should prove to be interesting, at least, if not, indeed, rather provocative and even potentially quite instructive in terms of proper, universally themed deictic and didactic.\nSo, in my expert opinion, as the world's very first, ever, formal fact theorist, my best answer to your question is, "Good Question!"\nKeep up the good work, and keep excellent track of your sources, even though they shall invariably change with "progress" and "improvement" such as that so far demonstrated by several millennia of so-so documented record. (Everyone, especially the Catholic Church, for example, wants to rewrite history. Even the noble scientists pursuing "nothing but the truth", and so on in their quest to convert followers to their newest, "modern" religion, in theory AND practice, have been known to tamper with data for personal ambition, just a bit too frequently for comfort, among other things...)

In a nut shell, the  rock it self contains  a  carbonaceous base substance like baking soda\n\n If you add vinegar to baking soda it will made the vinegar go up the same will happen to your rock if you add vinegar to it.

hhhmmmm....must be igneous...um...olivine. thats what it says. Pyroxene and plagioclase are also common

the meteorite and the core of the earth are assumed to both have formed around the same time.

Funny, I just watched this on the Discovery channel. Meteorites were stone falling from the sky, and not knowing how or why stone would fall from the sky.....you guessed it, the sky must be falling.

Shales can be changed into schist by way of moderate heat or shearing pressure accompanying regional (tectonic) deformation\n\nIf you are asking for specific minerals, it can be quartz, micas, amphiboles; often garnets, kyanite, or other aluminosilicates

Probably copper, which was one of several elements known to prehistoric man, and can be found in free form.  Carbon, as charcoal, might also qualify.

They burn up in the atmosphere.  Meteors are brilliant flashes in the night sky. They travel 60,000 km per hr.  At those speeds friction with air particles vaporizes an average size meteor in less that a second. The flash of light is caused by the intense heat of vaporization. Only on rare occasions a chunk large enough to survive the plunge hits the ground.  This is called a meteorite. The largest meteorites surviving the plunge do damage the surface of the earth and cause craters but this  rarely ever happens. You probably wont ever see it in your lifetime.

Diamonds are almost pure carbon with a few trace elements that give them color.  Coal is a complex hydrocarbon compound of which carbon is only a part.  Synthetic diamonds are made from graphite, another form of carbon, using heat and pressure.  Burning is rapid oxidation.  Diamonds do not burn at anything resembling a reasonable kindling  temperature if at all.  The carbon atoms in diamonds are so tightly bound to each other that it is very difficult to combine them with oxygen.

I cant tell you its value, but go to a geological estimator and ask to have a carbon test done for an estimated date of formation. With that date, an accurate value will be easier to ascertain with the services of an experienced fossil valuator.

Well, I am not a chemist.  If I had to take a stab at this I would GUESS it's because the ash is dry and not very absorbent and the kerosene is still able to give off enough fumes to be ignited.  However, the soil is moist and can absorb more of the fuel in such a matter than there aren't enough fumes to be easily ignited.\n\nThat's a guess.  I have never actually encountered what you are describing.

Hey does your question mean - how does fossilation happen\n\nMost fossils are found in sedimentary rocks, those rocks produced by the accumulation of sediment such as sand or mud. Wind and other weathering conditions wash away sediment on land, depositing it in bodies of water. For this reason, fossils of sea creatures are more common than those of land creatures. Land animals and plants that have been preserved are found mostly in sediments in calm lakes, rivers, and estuaries.\n\nThe likelihood that any living organism will become a fossil is quite low. The path from the organic, living world to the world of rock and mineral is long and indirect. In the best conditions, fossilization will occur if an animal or plant dies and is quickly covered over with moist sediment. This prevents the animal or plant from being eaten by other organisms or from undergoing natural decay through exposure to oxygen and bacteria. The soft parts of an animal or plant decay more quickly than its hard parts. Teeth and bones are therefore more likely to be preserved than skin, tissues, and organs. Because of this fact, most fossils come from the time period dating to almost 600 million years ago, when organisms began to develop skeletons and hard parts.\n\n=====================================\nAm not too sure of my German\n\nDie meisten Fossilien werden die von der Ansammlung der Ablagerung in sedimentären Felsen, die Felsen gefunden werden hergestellt wie zum Beispiel Sand oder Schlamm. Wind und andere Verwitternbedingungen waschen weg Ablagerung auf Land, deponierend es in Gewässern. Aus diesem Grund sind Fossilien von Seenkreaturen gemeinsamer als jene von Ländernkreaturen. Landen Sie Tiere und Pflanzen, die bewahrt worden sind, sind gefunden größtenteils in Ablagerungen in ruhigen Seen, Flüssen, und Gezeitenmündungen. \n\nDie Wahrscheinlichkeit, die irgendein lebender Organismus ein Fossil werden wird, ist ziemlich niedrig. Der Pfad vom organischen, Welt zur Welt von Felsen und Mineral lebend, ist lang und indirekt. In den besten Bedingungen wird Versteinerung stattfinden, wenn ein Tier oder Pflanze stirbt, und ist schnell über mit feuchter Ablagerung bedeckt. Dies verhindert das Tier oder die Pflanze, von durch andere Organismen gegessen zu werden, oder erlebend von natürlichen Verfall durch Aussetzung zu Sauerstoff und Bakterien. Die weichen Teile von einem Tier oder Pflanze verfallen mehr schnell als seine harten Teile. Zähne und Knochen sind daher wahrscheinlicher, als bewahrt zu werden, enthäutet, Gewebe, und Organe. Wegen dieser Tatsache kommen die meisten Fossilien vom Zeitraum datierend zu fast 600 Millionen vor Jahren, als Organismen begonnen haben, Skelette und harte Teile zu entwickeln.

With the air holes closed, there is a shortage of oxygen and the hydrocarbons in the gas do not burn completely. Some carbon is not burnt resulting in soot

Probably silicone and iron.   It's a friggin big rock.   Hollow it out a bit; near the center the gravity is probably near earths gravity.

Just calcium I think... chlorine, cobolt, copper are not and carbon by itselft should be either...

As I recall, this was once a major area of contention.  While coal can clearly (by the presence of plant fossils within it) be shown to come from resinous peat bogs which were altered later by pressure and heat, the origin of petroleum caused problems. While it is possible, within a catalytic cracker, to convert coal into tar (the Nazi war machine used this in WW II. It could be used in the US now, if not for the interference of oil companies (and the EPA).), most naturally occuring petroleum occurs in sandstones & shales, which have little plant materiel in them.  Whiile sandstone & shales are semi-permiable, so the oil could have seeped in and pooled at the bottom of a formation, there is still the problem of a source.  Eventually, it was noticed that foramifera, very small free floating creatures of all non-chlorinated bodies of water, have hard exoskeletons which are the main part of what we call sand (as compared with clay, which is fully digested rock).  Given this, the unimaginably huge numbers of them, and the fact that they have an organic/lipid content, led to the belief that they are the ultimate source of the oil.  It may be that there is also an anoxic biologic process, driven by archeo-bacteria, which consume lighter organics and polymerize them to generate energy for their oxygen-free life processes, which may be considered the source of petroleum.\n\nAs you no doubt know, crude oil is made up of many different organics molecules, some short chain, some long.  An oil refinery takes the mixed organics, heats them, separating them by vaporization and recondensation.  Some of the long chain molecues can be broken up, and this is done in a catalytic cracker, as we generally use more of the short lenght molecules than the long ones.
