Chondrites: ~ 86% of all meteorite cases, the majority of all found meteorites, they contain olivine and orthopyroxenes. (high nickel iron portion). Chondrites contain spherical chondrules, which consist of olivine and and/or pyroxenes/orthopyroxenes. Their nickel iron portion is high (5 to 20 %). Chondrites represent the building material, from that the solar system, the planets and our earth developed.
LL - Chondrites: "Low Metal", "Low Iron"
Type 3 chondritesare the originally received ordinary chondrites, the spherical silicate inclusions (chondrules) are well defined. This means, that type 3 chondrites do not origin from far depth of Asteroids like type 4, 5 or 6 chondrites, this types show less clear chondrules because of thermal metamorphism. Type 3 chondrites are unequilibrated chondrites, and types of 4 - 6 are equilibrated chondrites.
