摘要
柬埔寨贡布矿区基性-超基性岩浆岩带长约4km,侵入于晚石炭世陆源碎屑岩、片岩、碳酸盐岩中,呈岩墙产出。圈出的3条基性岩体为辉绿岩,Fe O、Mg O含量较高,属富铁质基性岩,其稀土元素球粒陨石分布型式为右倾型,属轻稀土富集型,形成时代为晚石炭世或以后。该岩体中已发现的磁铁矿(化)体,伴生钒、银等,基性岩体分布区是寻找大型铁矿床的有利地区。
A basic-ultrabasic magmatic rock belt extends for about 4 km in Kampot area, Cambodian and occurs as dykes in the Late Carboniferous terrigenous clastic rock, schist and carbonate rock. Magnetite ore (mineralization) associated with V and Ag mineralization is confined to the diabase which is characterized by enrichment FeO and MeO and LREE.
