摘　　要：本文着重研究了四川松潘东北寨金矿床的矿物学特征,提取了成因信息,分析了矿床成因类型,建立了"构造减压-沉积岩供金-地热流体(卤水)对流循环成矿"成矿模式.作者们认为:东北寨金矿床属于浅成低温热液成因金矿,并可与陕西二台子、宁夏金场子、美国卡林等卡林型金矿对比.其外围及深部均有极佳远景.This paper mainly deals with the mineralogical characteristics from which genetic information of Dongbeizai gold ore deposit is extracted. The metallogenic model of 'pressure reduction caused by tectonic actiVity——gold provided by sedimentary rock——gold transported by circulated geothermal brine to enrich to ore' is established on the ore genesis. This deposit is an epithermal gold deposit which can be correlated to Ertaizi Au-deposit, Shanxi Province, Jinchangzi Au-deposit, Ningxia Autonmous Region and Karlin Au-deposit, US. Its surrounding areas and deep levels are all ecxellent potential areas for futher gold prospecting.
