海南岛金矿控矿因素浅析

前古生代变质地层是海南岛金矿重要的矿源层,海西印支期-燕山期酸性侵入岩浆为金矿的形成提供热源和部分成矿物质,构造控制着金矿的空间定位和形态,金矿的典型类型有岩浆热液石英脉型和破碎带蚀变岩型。

This paper analyse the product of structure-magma evolvement which has close relation with gold mineralization and their ore-controlling of gold deposit formation in Hainan island. It shows that pre-Mesozoic metamorphic rocks is important source bed, Hercynian-Indochina and Yanshan period magmatism and shear zones are important ore-controlling factors of gold mineralization. Some gold deposits are formed such as broken belt altered rock type gold deposit and hydrothermal quartz vein-type gold deposit.
