SNC Meteorites

Most researchers accept that SNC meteorites were part of the regolith layer of Mars as their composition is similar to that of the Martian regolith analyzed by space probes Gas inclusions found in some SNC meteorites resemble the Martian atmosphere in isotopic composition It is believed that these

Chronology of SNC meteorites

Abstract In this paper amodel ispresented for he geochemical evolution of Mars which isconstrained by the isotope systematies ofPb Nd and Sr determined for SNC meteorites (SNC The ) young magmatic crystallization ages (internal mineral ages) of SNCs may indicate that hese meteorites indeed stem from Mars

Are nakhlite and chassigny meteorites found on Mars?
The Mars Pathfinder mission and recent speculation about the existence of primitive life on Mars have intensified the interest in the shergottite, nakhlite and chassigny (SNC) meteorites, which are widely believed to originate from Mars. More than ten years have past since Treiman et al. (1986) summarized compositional data for SNC meteorites.
Where did the SNC meteorites come from?

How many meteorites have a standard deviation?
For example, nine meteorites have more than three individual analyses for K. The standard deviation is I1 5% for five meteorites, and four have devia- tions >25%. Similarly for La, another LIL element, three out of seven meteorites that have been analyzed more than three times have standard deviations 4 5%.

Where did the Shergotty meteorite come from?

As early as 1872, Tschermak recognized that the Shergotty meteorite was a basalt that formed under relatively oxidizing conditions, but it wasn’t until 100 years later that it became apparent to meteoriticists that the relatively young SNC* meteorites may have come from the planet Mars (Walker et al. 1979, Nyquist et al. 1979).

Do Martian meteorites result in glass?

Are Martian meteorites igneous rocks?

Although the Martian meteorites so far identified are igneous rocks, they include some entrapped Martian atmosphere (Bogard and Johnson 1983, Leshin et al. 1996), some alteration products (Gooding 1978), some salts (Bridges et al. 2001) and possibly, some melted soil (Rao et al. 1999).
