摘　　要：隆瓦寺院金矿大地构造位置属西秦岭褶皱带,位于中北秦岭加里东、燕山期铅锌、金、铜、银、锑、钼成矿带的夏河—合作金、铜成矿带上,与早子沟金矿床位于同一成矿带。本文通过对矿床区域地质背景、矿床地质特征及地球化学特征等进行综合分析,总结了矿床控矿因素及找矿标志。研究认为该矿床受地层(岩性)、断裂构造及侵入岩等因素控制,为一中低温热液构造蚀变岩型金矿床。The geotectonic position of Longwasiyuan Gold Deposit belongs to the West Qinling fold belt, located in the North Qinling Caledonian.Yanshan epoch Lead and Zinc, Gold,Copper,Silver,Antimony,Molybdenum metallogenic belt, and Xiahe-Hezuo Gold,Copper metallogenic belt. and it,s located in the same metaUogenic belt with Zaozigou Gold Deposit. Based on the geological background, geological characteristics and geochemical characteristics of ore deposits, this paper analyzes the controlling factors of ore deposits and summarizes the prospecting signs. The research indicates that the deposit is controlled by the stratum （lithology）, tectonic and intrusive rocks, and is a tectonic alteration rock type gold deposit.
