摘    要：北岭大型构造蚀变岩型金矿床是应用化探找金的一个成功范例,矿区发育有与金矿关系密切的地球化学异常,沿F881构造蚀变带走向,As与Au的组合异常通常与金的矿体晕分布一致,而As、Sb组合则更多反映了矿体前缘晕的组合特点。系统总结了北岭金矿区的地球化学特征,并归纳了构造蚀变岩型金矿床的地球化学找矿标志。

Abstract: Beiling tectonic altered rock type gold deposit is a successful application example of geochemical prospecting.Geochemical anomalies,which are closely related to gold deposits,develop in the ore district.Along the F881 tectonic alteration belt,the anomaly association of As and Au usually distributes in accordance with the gold orebody halos,while the association of As and Sb usually reflects the compounding features of orebody front halo.The geochemical characteristics of Beiling gold deposit are concluded systematically.The geochemical prospecting criteria of tectonic altered rock type gold deposit are summed up.
