云南富宁者桑金矿控矿条件及找矿方向分析

Analysis on Ore Controlling Condition and Prospecting Direction of Zhesang Gold Deposit in Funing of Yunnan

者桑金矿地表氧化矿已基本采完,现面临寻找接替资源,维持矿山生产的难题。矿山对深部原生矿未做工作,最近在进行生产勘探时有少量深部钻孔发现原生矿,矿体受北东向断裂和侵入岩体与围岩接触带控制;金矿化与基性岩浆活动关系密切。原生矿的发现提供了深部找矿线索,本文试图从分析金矿的基本地质特征入手,探索该矿的控矿条件及指出下步找矿方向,为矿山可持续发展、寻找金资源保障提供参考。

The surface oxide ore of Zhesang gold deposit almost has been mined out, seeking replace resource and keeping mine production are the present problems. The exploration of primary ore has not finished, the primary ore has been found in few deep drills recently, the orebody is controlled by NE fracture, erosion rock and wall rock contact zone. Gold mineralization has close relationship with basic rock magmatic activity. The discovery of primary ore supplies clues for deep exploration, by analysis the basic characteristics of gold deposit, ore-controlling factors of this deposit is found and the future prospecting direction is carried out, it will support guidance for mine sustainable development and gold exploration.
