摘要:

Nine, possibly ten, stones from northwestern Missouri are known as the Faucett meteorite. These stones are finds, but may be fragments of a large fireball seen in the area in 1907.

Modal analysis gives: olivine 43%, orthopyroxene 28.3%, oligoclase 5.9%, glass 1.2%, metallic grains (both nickel‐iron and troilite) 19.7%, other minerals and unidentified grains 2.0%. The chemical analysis is typical of modern analyses of H‐group chondrites with a total iron value of 26.59 weight pe
