about Tafassasset

partly extract from MB86

„Carbonaceous chondrite (equilibrated CR-like meteorite) or primitive 
achondrite „ -----

-----

„ A 3.61 kg stone, labeled "*Te-1*", was found in 2000 March, probably 
on the same expedition noted above, and is reported by J. Otto (/Frei/) 
to have been found in the Tenere Desert at 20°45.8' N, 10°26.5' E. 
Classification (J. Otto and A. Ruh, /Frei/): a primitive achondrite; 
partly covered with black fusion crust; shows a recrystallization 
texture with abundant 120° triple junctions dominated by olivine (56 
vol%, 100–700 µm, Fa_28.7 , 0.06 wt% CaO) and poikilitic orthopyroxene 
(23 vol%, up to 3 mm, Fs_25.4 Wo_3.6 ) with exsolved clinopyroxene 
(Fs_12.7 Wo_39.7 ); Fe-Ni metal is irregulary distributed (~10 vol%, up 
to 5 mm); poikilitic plagioclase occurs in interstices (6.5 vol%, 
An_38.5 Or_3.7 ); troilite (~3.5 vol%, 0.01 wt% Ni); chromite (~1 vol%, 
Fe/(Fe + Mg) = 0.817, Cr/(Cr + Al) = 0.818). Oxygen isotopes (R. Clayton 
and T. Mayeda, /UChi/): δ^17 O = -0.85‰, δ^18 O = +1.70‰, *different 
from other achondrites*. Noble gases (L. Schultz, /MPI/): *data 
compatible with those of brachinites*; exposure age is ~45 Ma. Shock 
stage, S1/2; weathering grade, W0. Specimens: main mass with Christian 
Stehlin, Basel; type specimen, 30.2 g and thin section, /Frei/. „
