Bustee vs Semarkona

Bustee is an aubrite meteorite that fell in northern India in 1852. Aubrites are rare, highly reduced achondrites composed predominantly of enstatite, with mineral chemistry indicating formation under conditions containing very little oxygen. As a documented nineteenth-century fall, Bustee provides researchers with material for investigating enstatite-rich parent bodies and the early differentiati...

Semarkona is an LL3.00 ordinary chondrite that fell near Semarkona, India, in 1940. Its minerals experienced exceptionally little thermal metamorphism on their parent asteroid, preserving chondrules, fine-grained material, and other evidence from the early solar system. Researchers use it to investigate primordial water, organic chemistry, magnetic fields, and the processes that formed the first s...
