摘要
四川康滇地轴钒钛磁铁矿以大、中型为主,均分布在层状基性、超基性岩体中,该类型铁矿分为基性岩浆分异型和基性—超基性岩浆分异型2个亚类。对区域矿产三大成矿系列时空演化规律和钒钛磁铁矿含矿岩体的成矿系列进行了阐述,并从地质构造条件、含矿层状岩体的侵位、岩体生成时代及形成深度、围岩性质对成岩成矿的影响、岩浆来源、岩浆演化特征、岩体和矿床的成因等方面对钒钛磁铁矿成矿规律进行了探讨。
Vanadic titanomagnetite deposits in the Kangdian Axis, Sichuan are confined to layered basic and ultrabasic intrusions. They may be divided into two subtypes such as basic magmatic differentiation subtype and ultrabasic magmatic differentiation subtype. This paper deals with time-space evolution for three minerogenetic series of ore deposits and host intrusions with geological setting, time and depth of intrusion emplacement, character of wall rock and its influence on diagenesis and mineralization, magmatic origin and evolution and genesis of intrusions and vanadic titanomagnetite deposits.
