Meteoritical Bulletin n°
87 (2003)
Classified by :
MNHN Paris & Blaise Pascal University - Clt. Fd
Type :
L3.8 non équilibrated
Weathering grade :
W1
%Fa :
0.5-22.7% - mean 18,6%
%Fs : 3.4-28.5% - mean 15,6%

Fairly aletered, with rests of fusion crust on the side that was on the soil.
Same type as Acfer 336, but those 2 meteorites are not paired (Acfer 337 is fresher).
Despite the average rate of fayalite (18,6%) that could lead to H type, abundance of metal observed under optical microscope, proves that it is a L type.
