Writeup from MB 111:
Abadla 003 30°28’58.07" N, 01°37’15.76"W Bechar, Algeria Purchased: 2022 April 3 Classification: Carbonaceous chondrite (CM2) History: Found in the Abadla DCA, Algeria, on December 22, 2021 Petrography: (K. Metzler, IfP) Chondrules, chondrule fragments, and CAIs are embedded in a fine-grained black matrix (about 50 vol% matrix). The vast majority of chondrules belong to the chemical type I. Chondrule sizes are mostly between 50 and 300 µm; a few chondrules with sizes up to 800 µm are present. Many chondrules are mantled by fine-grained dust. Accessories are troilite, pentlandite, and calcite. The presence of hydrous phyllosilicates is indicated by the low totals of bulk matrix analysis Geochemistry: Mineral compositions and geochemistry: Random measurements of olivine grains revealed Fa8.9±12.9 (Fa0.5-35.0); n=16. Random measurements of low-Ca pyroxene grains revealed Fs1.9±1.6 Wo2.0±1.2 (Fs0.7-4.9 Wo0.7-3.6; n=10) Classification: CM chondrite based on CAI occurrence, small chondrule size, chondrule-matrix ratio, and mineral chemistry. Petrologic type 2 based on the large chemical variations of olivine and pyroxene and low totals of matrix analysis | ||||||||||||||||||||||||||||||||||||
