许多超镁铁质或镁铁质杂岩体常伴生有大型的工业铬矿、磁铁矿矿床。但矾山杂岩体却以产出层状磁铁磷灰岩和磷灰岩形成独特的大型磷铁矿床为其特征。本文试图根据现有的矾山杂岩体矿物、岩石、地球化学研究成果,结合实验研究资料构制该岩体中磁铁磷灰岩及磷灰石岩形成的模式,我们的认识不一定妥当,提出来和大家讨论。 Many ultramafic or mafic complexes are often associated with large-scale industrial chromite and magnetite deposits. However, the Doushan Complex is characterized by the formation of a unique large-sized phosphate iron deposit by the production of layered magnetite and apatite. Based on the existing mineral, rock and geochemical research results of the Fanshan complex and the experimental research data, the paper attempts to construct the pattern of the formation of the magnetite and apatite in the rock. Our understanding may not be proper, Proposed to discuss with everyone.
