安徽省东至县大西峰尖地区斑岩型铜金矿成矿地质条件研究

STUDY ON METALLOGENIC GEOLOGICAL CONDITIONS OF PORPHYRY COPPER AND GOLD DEPOSITS IN THE DAXIFENGJIAN AREA,DONGZHI COUNTY,ANHUI PROVINCE

安徽省东至县大西峰尖地区主要出露志留纪地层,深部岩浆岩较发育,以高钾钙碱性岩石为主,物化探异常较强,蚀变分带明显,是东至地区寻找斑岩型铜金矿床的有利地段。本文探讨了该区的成矿地质条件,为今后在该地区的找矿工作提供参考。

Silurian strata outcrop mainly in the Daxifengjian area of Dongzhi County,Anhui Province,where magmatic rocks are well developed in the deep,which are dominated by high-potassium calcium-alkaline rocks.The geophysical and geochemical anomalies are strong,with remarkable alteration zoning,so it is a favorable area for searching porphyry coppergold deposits in the Dongzhi area.This paper discusses the ore-forming geological conditions in this area,which is of certain reference significance to the ore-prospecting work in this area in the future.
