Writeup |
Writeup from MB 108:
Northwest Africa 12602 (NWA 12602) (Northwest Africa) Purchased: March 2017 Classification: Ordinary chondrite (H4, melt breccia) History: Purchased by Sean Tutorow and Brahim Tahiri from meteorite hunters in Morocco. Petrography: The rock is a melt breccia. Melted regions are dark; they contain numerous metal-sulfide veins, polycrystalline troilite and rare cellular, rapidly cooled metal-sulfide assemblages. There are rare grains of coarse troilite. Most metal grains are not attached to sulfide grains. Some low-Ca pyroxene grains exhibit polysynthetic twinning, perhaps caused by post-shock quenching. There is strong mosaic extinction evident in the olivine grains. | ||||||||||||||||||||||||||||||
