安徽和县香泉-拦龙山一带金矿找矿远景初步分析

A preliminary analysis on prospects for gold exploration in the Xiangquan-Lanlongshan area,Hexian County,Anhui

安徽和县香泉已发现有中型规模的独立铊矿床。香泉-拦龙山一带地表具有较为明显的低温元素组合异常,同时还具备卡林型金矿形成所需要的不同构造单元的结合部位和构造过渡带位置、逆冲断层、地热及隐伏岩体等条件。本文在对以往区域地质工作成果资料分析的基础上,结合本人在香泉铊矿勘查工作中的认识,从区域地质背景、远景区地层条件、金矿源层、构造条件、岩浆岩条件、成矿流体驱动力源等方面,初步分析认为香泉-拦龙山一带具备金矿的找矿远景。

Amedium-sizedthallium-only deposit has been found in Xiangquan,Hexian County,Anhui Province.The Xiangquan-Lanlongshan area that exhibits significant anomalies of low-temperature element associations on the surface is favorable to formation of Carlin-type gold deposits in terms of the location where different structural units meet,structural transition zone,thrust fault,geotherm,and pluton.By analyzing previous work results of regional geological survey,combined with our knowledge from thallium exploration in Xiangquan,it is concluded that there are prospects for gold exploration in the Xiangquan-Lanlongshan area based on regional geological setting,stratigraphy in the target area,gold source bed,tectonic conditions,magmatic rock conditions and driving source of ore-forming fluid flow.
