Ordinary chondrites;  By far the most numerous of the meteorites that hit the earth (about 85%), these chondrites are classified by iron content and further by the degree of metamorphic alteration of chondrules seen in the individual specimen. There are three types of ordinary chondrites.
The "H" chondrites are considered to have formed outward from the sun beyond the earth's orbit with the "L" parent body forming farther out and the "LL" parent body farther yet from the sun.
High iron (H) have 25 - 31 % total iron with 15 - 19% metallic iron.
Normal range iron (L) have 20-25 % total iron with 4 - 10% metallic iron and a
Low iron (LL)have 19-22 % total iron with 1- 3% metallic iron
