摘　　要：位于秦岭—祁连—昆仑造山带的大水金矿是我国八十年代末期发现的一处大型金矿。在大水金矿的地质勘查过程中,发现整个金矿的地质情况较为复杂,并且其矿床类型也较为特殊。经过对大水金矿的地质勘查以及对成矿因素进行分析发现,金矿整体是在印支时期的岩浆活动与燕山时期的内陆造山运动中受到岩浆活动、地质断裂、岩性变化等多种因素共同影响形成的富集型金矿。Dashui gold deposit located in Qinling Qilian Kunlun orogenic belt is a large gold deposit discovered in the late 1980s in China.In the process of geological exploration of Dashui gold deposit,it is found that the geological situation of the whole gold deposit is relatively complex,and its deposit type is also relatively special.Through the geological exploration of Dashui gold deposit and the analysis of metallogenic factors,it is found that the gold deposit as a whole is an enriched gold deposit formed under the joint influence of magmatic activities,geological faults,lithological changes and other factors in the Indosinian period and the Yanshan period inland orogeny.
