卖家的描述
Meteorite, split and polished individual with some fusion crust and black schock vein from the Asteroide Vesta
Northwest Africa 15658
2022
Classification: HED achondrite (Eucrite, melt breccia)
Mass : 5845 g
Shock stage: high
Weathering grade: low
Physical characteristics: Dark grayish rock with some fusion crust
Petrography: Eucrite-melt breccia composed of up to 3 cm sized basaltic clasts and up to 500 µm sized mineral fragments in black shock melted matrix. Main minerals are exsolved pyroxenes and calcic plagioclase. The shock melt is mostly finely recrystallized and partly displays flow textures. Mineral grains entrained in the melt matrix often show resorption textures. Minor phases include silica, chromite, ilmenite, and FeS. No metallic iron detected.
endcut #1 - 55.3 g - 56 x 48 x 15 mm
endcut #2 - 64.4g - 57 x 48 x 17 mm
International meteorite collector association member number #3503
