摘要
二密铜矿床主要位于燕山期石英闪长岩体东段，矿体分布在石英闪长岩体内外接触带上，以脉状、细脉状、细脉浸染状、浸染状矿体为主，成群成带分布。岩体和矿脉原生硫化物同位素测定结果表明：成矿热液与花岗斑岩、石英闪长岩具相同的硫源。在研究铜矿床地质特征的基础上，指出二密铜矿床的矿床成因类型为中温热液型矿床，并建立了矿床成矿模式。
The copper deposits are mainly located in the eastern part of the quartz diorite rock body in the Ermi Mesozoic volcanic basin. The ore bodies are distributed in a group zone in the inner and outer contact zones with the structures of vein type, veinlet type, veinlet-disseminated type and disseminated type. According to the isotope determination data of the primary sulfide from the vein and rock, it is suggested that the vein′s sulfur source is similar to granite porphyry and quartz diorite. Its mitallogery belongs to mesothermal deposit.The metallogenic model was established on the basis of the study.
