Date of find :
May 12, 2002
Total mass :
132 g
# of fragments :
7 fragments
Place : Acfer (Algeria)
Meteoritical Bulletin n°
90 (2006)
Classified by :
MNHN Paris & Blaise Pascal University - Clt. Fd.
Type :
L3 (non equilibrated)
Shock stage : S5
Weathering grade :
W1
%Fa :
20,4 +/- 4%
%Fs : 14,8 +/- 4,8%
Remarks :
Quite fresh with fusion crust, it is a beautiful chondrite. Found near by Acfer 336 & Acfer 337, those 3 meteorites are different from each other, from their structures and weathering grades.
In spite of %Fa = 20,4 +/- 4%, observation under optical microscope shows that Acfer 341 is a type L chondrite.
But additional analyses would be necessary to determine precisely if it is a 3.7 or a 3.8 type. Nomenclature Committee has decided to classify it as a L3 (MB90 - 2006)
