Comparison between clasts of the Tatahouine diogenite, collected the day of the fall in 1931 and 63 years later in 1994, allows the evaluation of mineralogical and chemical effects of terrestrial residence on meteorites. Secondary minerals are found in the ...
SNC meteorites (Shergottites, Nakhlites and Chassigny) define a fractionation line in a delta(17)O/delta(18)O diagram as expected for rocks differentiated from a formerly homogenized parent body, which is intermediate between H ordinary chondrites and EH e ...
The complete (or near complete) differentiation of a chondritic parent body is believed to result in an object with an Fe-Ni core, a thick olivine-dominated mantle and a thin plagioclase/pyroxene crust. Compositional groupings of iron meteorites give direc ...
We report findings of large metal grains (~150 um) with distinct zoning patterns in Ni, Co, Cr, and Si in CH chondrites which are consistent with a condensation origin from a gas of solar composition. ...
