摘要
通过对洋灰洞子铜矿床的成矿岩体进行研究,进一步明确了其成矿地质背景,着重研究与铜钼矿床关系密切的花岗闪长岩体和花岗闪长斑岩体的岩性特征、岩石类型、岩石化学特点、成岩时代、物质来源及侵位方式等,确定了该区花岗闪长岩和花岗闪长斑岩为洋灰洞子斑岩型铜钼矿床的成矿母岩。
The ore forming magmatic body associated with the Yanghuidingzi copper deposit was studied with a focus on the lithological characteristics, rock types, rock geochemistry, metallogenic era and matter source of the granodiorite and granodiorite porphyry rocks closely associated with copper and molybdenum ore deposit.The granodiorite and granodiorite porphyry rocks of the region are confirmed to be the host rock of the Yanghuidongzi porphyry copper and molybdenum ore deposit.The result of the research is significant to the searching of porphyry type of copper deposit.
