Macroscopic Description: René Martinez and Cecilia Satterwhite All of these hand-specimens show light and dark chondrules and angular fragments in contrast with a darker, very coherent matrix. Some of the chondrules are rimmed and range from <1 mm to ~4 mm diameter.
Thin Section (LEW86127,2; 86134,3; 86144,2; 86158,2; 86207,3; 86246,2) Description: Brian Mason These meteorites are very similar in all respects and are possibly paired. The sections show a close-packed aggregate of chondrules and chondrule fragments, up to 3 mm across, in a minimum amount of fine-grained dark matrix which contains a little nickel-iron and troilite. Chondrule types include granular and porphyritic olivine and olivine-pyroxene, barred olivine, and radiating and cryptocrystalline pyroxene. Weathering is extensive, with brown limonitic staining throughout. Microprobe analyses show olivine and pyroxene with a wide range of composition: olivine, Fa1-29; pyroxene, Fs1-21. The low content of nickel-iron suggests L group, and the wide range of olivine and pyroxene compositions type 3; thus these meteorites are tentatively classified as L3 chondrites (estimated L3.5). | ||||||||||||||||||||
