摘　　要：石柱金矿位于黔西南贞丰县,是烂泥沟金矿外围的一处小型卡林型金矿床。本文基于野外地质勘查工作和各类岩矿测试结果,系统总结了矿床的地质特征和矿石特征,指出矿区的矿体主要受构造控制,矿石工业类型为少硫化物微细粒浸染型难处理金矿石。矿化富集规律研究成果显示,矿体具有NEE向倾伏的特征,在深部有尖灭再现的可能;在此基础上,提出石柱金矿与烂泥沟金矿具有相似的成因,并建立了烂泥沟—石柱金矿田的成矿模式。Shizhu Au deposit is a small Carlin type Au deposit located in the periphery of Lannigou Au deposit in Zhenfeng county of the Southwest Guizhou province.This paper summarizes geological and ore characteristics of the deposit.Ore bodies are mainly controlled by structure.The ore is micro-disseminated refractory Au ore with little sulfides.The ore body is characterized by NEE pitch,possibly pinching out or reappearing to depth.The Au deposit is genetically similar to Lannigou Au deposit thus Metallogenic model of Lannigou-Shizhu Au ore field is built.
