摘要
海沟金矿床具有多源、多期、多阶段成矿的特点，成矿主要与燕山早期花岗闪长岩及闪长玢岩有关。对其矿床地质特征、同位素地质学、矿床成因及成矿模式等方面研究，认为成矿物质来源具双重性，即有来源于地层，也有部分来自岩浆岩。成矿水为岩浆水和大气降水的混合，成矿热源为燕山期花岗闪长岩。
The Haigou gold deposit features multi-source, multi-period and multi-sta ge in m ineralization, which is mainly related to early Yanshannian granodiorite and por phyrite diorite. Studies on geology, isotopes, metallogenesis and metallogeic mo del indicate that the ore-forming material derives from strata and magma, the or e-forming fluid derives from mixing of magmatic water and meteoric water and the heating source is Yanshanian granodiorite. The Haigou gold deposit belongs to u ranium-gold deposit related originally to migmatizing hydrothermal process.
