Stony Meteorite

Meteorite composed of silicate minerals, but that may have up to 25% Ni-Fe metal by weight. Stony meteorites are extremely heterogeneous as a group, ranging from samples of primordial matter that have remained more or less unchanged for the last 4.56 Ga (chondrites) to highly evolved younger rocks from differentiated worlds, such as the Moon or Mars (achondrites). They account for 95% of all known falls, the majority (86% of all falls) being chondrites.
