Acfer 337 : L3.8 © Meteoriteshow  

Official name : Acfer 337
Date of find : May 10, 2002
Total mass : 360 g
# of fragments : 1 fragment
Place : Acfer (Algeria)
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%
Remarks : 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.
