What is a chondrite in geology ?
Chondrite : definition
Chondrite is a generic name given to stony meteorites made up of more than 80% Si, Mg and Fe. Chondrites are made up of chondrules, silicate spherules of small sizes made up mainly of orthopyroxenes, olivine and rare plagioclases, embedded in an ultrafine silicate matrix (less than 0.01 mm) of the same composition, and comprising grains of metal alloys and sulphides. Chondrites are the most common meteorites, accounting for 85% to 90% of falls on Earth.
