Properties of chondrules

摘要: Chondrules contain a record of many essential characteristics the primordial solar nebula, whose high-temperature chondrule-generating events have spanned nearly 10 million years. As chondrules cooled, they became magnetized by nebular fields; chondrule rims show that dust was present in vicinity formation, and multiple melting were possible. The precursors included large grains, showed variable degrees Fe-oxidation, encompassed isotopic reservoirs. properties these materials systematically changed from enstatite, to ordinary, finally carbonaceous chondrite formation regions.
