Another extremely rare stony-iron type called Siderophyre and consist of taenite and orthopyroxen. The most usual minerals in stone meteorites are olivine and pyroxenes. The common accessory minerals are plagioclases, NiFe alloys. Quartz, amphiboles, micas, serpentine, chlorite, troilite are rare minerals. The maine subdivision of stone meteorites is according to it's structure to chondrites and achondrites.
Chondrites are the most common type.
It's name came from small spherical inclusions called chondrules. This texture not found in terrestrial rocks. The chondrules's average size is 1 mm, rarely up to 5-7 mm. Chondrules different in structure but have the same mineral constitution as surrounding masses. The genesis of chondrules is unclear.
