    stony meteorite

    A meteorite composed of mostly silicate minerals (75-90% by weight), together with nickel-iron metal alloy (10-25%), and iron sulfide. Stony meteorites are a very varied group, ranging from virtually unaltered samples of matter that date back to the dawn of the Solar System, some 4.55 billion years ago, to rocks with a complex history that have come from large differentiated worlds, such as the Moon or Mars.

    Stony meteorites account for 95% of all known falls. The majority (86% of all falls) are chondrites, the rest are achondrites.
