摘　　要：西秦岭造山带是中国最重要的金成矿带之一,其内已发现早子沟、加甘滩、以地南、加木龙等多个大型—超大型金矿床,且金矿床的形成多与中酸性侵入岩关系紧密。在总结前人成果基础上,实施野外项目时,在甘肃省夏河县的姜隆哇地区首次发现了姜隆哇岩体。通过对地质特征、水系沉积物地球化学特征、地面高精度磁法地球物理特征的研究,结合姜隆哇岩体特征,认为姜隆哇地区具有寻找金多金属矿的找矿前景。经异常查证,发现了矿化体,该找矿思路可为姜隆哇地区周边同类型矿床勘查工作提供一定参考。West Qinling orogenic belt is one of the most important gold metallogenic belts in China,where large and super-large gold deposits have been found,such as Zaozigou,Jiagantan,Yidinan,Jiamulong and so on.The formation of the gold deposits is closely related to intermediate acidic intrusive rocks.On the basis of summarizing predecessors'achievements,the Jianglongwa rock mass is discovered in Jianglongwa area,Xiahe County,Gansu Province for the first time in field projects.Based on the study of geological characteristics,stream sediment geochemical characteristics and geophysical characteristics of ground high precision magnetic,as well as the characteristics of Jianglongwa rock mass,it is believed that prospecting potential for finding gold polymetallic deposits in Jianglongwa area.Verified by anomalies,mineralized bodies have been discovered.This prospecting approach provides certain reference for the prospecting of similar deposits in the surroundings of Jianglongwa area.
