霍山县梅家岗地区地质、化探异常特征及找矿方向探讨

DISCUSSION ON GEOLOGICAL AND GEOCHEMICAL ANOMALY CHARACTERISTICS AND PROSPECTING DIRECTION IN THE MEIJIAGANG AREA,HUOSHAN COUNTY

霍山县梅家岗地区位于安徽省西部大别山东部北麓,江淮分水岭北缘,区域上属于桐柏-大别造山带的东段,桐柏一桐城断裂(安徽境内亦称磨子潭—晓天断裂)的北侧,构造带上应归属北淮阳构造带。通过1:5万水系沉积物测量及1:1万异常查证,基本查明了区内Au、Cu、Pb、Zn、Ag等元素含量的空间分布和富集特征,本篇重点研究霍山县梅家岗地区各元素化探异常特征,进一步探讨找矿方向。

The Meijiagang area of Huoshan County is located at the northern foot of the eastern Dabie Mountain in western Anhui Province,on the northern margin of the Jianghuai watershed,regionally belonging to the eastern part of the Tongbai-Dabie orogenic belt,and the northern side of the Tongbai-Tongcheng fault(also known as the Mozitan-Xiaotian fault in Anhui Province),and tectonically to the Northern Huaiyang structural belt.The spatial distribution and enrichment characteristics of Au,Cu,Pb,Zn,Ag and other elements in the area were basically identified by the 1:50,000 stream sediment survey and 1:10,000 anomaly verification.This paper focuses on the geochemical anomaly characteristics of various elements in the Meijiagang area,Huoshan County,to further explore the direction of ore exploration.
