湘东南张家垄钨矿床综合找矿模型及其意义

Integrated prospecting model and significance of the Zhangjialong tungsten deposit in the southeastern Hunan

湘东南张家垄钨矿位于炎陵—汝城冲断褶隆带中部,处于炎陵—郴州NE向构造岩浆岩带与汝城—安仁NW向构造岩浆岩带交汇部位之南侧彭公庙岩体南部,是首次发现产于湘东南彭公庙加里东期花岗闪长岩体内外接触带中的大型构造蚀变岩型、石英脉型白钨矿床。通过对张家垄钨矿床地物化遥等综合找矿信息进行综合分析研究,建立综合找矿模型和成矿模式,指导矿产勘查工作,实现了找矿突破。

The Zhangjialong tungsten deposit, occured in the southern Penggongmiao intrusion, is located in the faulted-folded -uplift area from the Yanling to Rucheng and the southern coast of the intersection of the NE-trending Yanling-Chenzhou tectono magmatic belt and the northwest-trending Anren-Rucheng tectono magmatic belt. It was the large-sized structural altered-rock type and quartz vein type tungsten deposit which was the first discovered in southeasten Hunan, the orebody occurred in inner and outer contact zone of the Caledonian Penggongmiao granodioritic intrusion. Through integrated analysis of various prospecting information such as geological, geophysical, geochemical, remote sensing data in the Zhangjialong tungsten deposit, the integrated prospecting model and the metallogenic model were constructed for guiding further exploration in order to achieve great prospecting breakthrough.
