陨硫铁发现于山东、辽宁新生代碱性玄武岩所携带的幔源巨晶辉石等矿物中。两地的陨硫铁由于载体的巨晶辉石与碱性玄武岩之间曲混融程度不同,导致他们的稀土配分型式亦不同,即混融程度高,稀土配分型式复杂,混融程度低,则稀土配分型式与球粒陨石的配分型武相同。幔源陨硫铁以富镍为特征,并且是在特定的物理化学条件下生成的,即 The pyrite was found in minerals such as mantle-derived giant crystallopyxene carried by the Cenozoic alkaline basalts in Shandong and Liaoning Provinces. Due to the different degree of mixing of the crystalline pyroxene and basic basalt in the two places, the two types of meteorites contain pyrites, which lead to their different types of rare earth compounds. That is, the degree of mixing is high, the complex types of rare earths are complex, The type of rare earth particles with chondrules with the same type of weapons. Mantle-derived meteorites are characterized by nickel enrichment and are produced under specific physico-chemical conditions, namely
