[meteorite-list] Sahara 99555, a "Rosetta Stone"! OT: Tired of untruths!

[David Weir]

Hello Martin,

Here is my synopsis of info from the latest R chondrite paper (and 
others) as it concerns the Labenne's pieces. They show some differences 
but are most likely paired of course:

------------------------------------------
A single mass of 19 g was found in the Sahara Desert, the location of 
which is presently being maintained in confidence by the French search 
team. Along with two other small masses, the 31 g Sah 99531 (R3-5) and 
the 27 g Sah 99537 (R3-6), both of which were recovered in close 
proximity to Sah 99527, this may represent a single fall of a brecciated 
meteorite. Consistent with this theory is the fact that all three 
meteorites have the same shock stage (S3) and a similar weathering grade 
(W3/4 vs. W4 for Sah 99527). Sahara 99527 was classified at the Institut 
für Planetologie in Münster. Unlike its two pairings, Sahara 99527 does 
not contain solar noble gases, and it is therefore considered to be a 
solar gas-free inclusion within a larger regolith breccia. It has a 
21Ne-based CRE age of 29.2 m.y. (Schultz et al., 2005).
