摘　　要：河北丰宁大西沟金矿地处华北板块北缘冀北——辽西成矿区,是一个研究程度较低的矿床。文章从地质、地球化学的角度初步研究了该矿床的微量元素、稀土元素和成矿流体的特征,并对矿床成因做了初步的讨论。研究表明,大西沟金矿是与陆相次火山作用有关的中浅成中低温热液(蚀变岩)型金矿床。The Daxigou gold deposit is located in the north Hebei & west Liaoning ore-forming district in the northern part of the Huabei plate and the research degree is lower.This article has studied the characteristics of its trace elements,rare-earth elements and the ore-forming fluid and made a discussion on the genesis of the deposit.The study shows that the type of the Daxigou gold deposit is a low to moderate temperature and low to moderate salinity hydro-thermal gold deposit which is related to continental sub-volcanism.
