铜陵凤凰山铜多金属矿床花岗岩侵入与成矿关系
|
摘要
通过对铜陵凤凰山新屋里岩体化探样测试数据的系统分析研究,初步确定了岩体的成因、成矿意义,并对其侵位机制进行了探讨。在此基础上,针对与岩浆相关的蚀变作用,主要有大理岩化、夕卡岩化、硅化、钾化(包括黑云母化和钾长石化)、绢云母化、黄铁矿化、泥化、绿泥石化、绿帘石化和碳酸盐化等的具体分析,表明了新屋里岩体具有巨大的成矿潜力,不仅可以在其接触带上找到较富的夕卡岩型铜矿,而且在其边部及岩体的深部同样有可能找到规模较大的斑岩铜矿床。
Based on geochemical prospecting data on the Xinwuli rock body in the Fenghuangshan deposit at Tongling,Anhui Province,origin and mineralizing signification of the rock body is preliminarily ascertained,and intrusive mechanism of the body is analyzed.Strong alterations related with magma like marbleization,skarnization,silicification,kaliumization(biotitization and potassium feldspathization),sericitization,pyritization,argillation,chloritization,epidotization and carbonatization,show that the Xinwuli rock body has great potential of mineralization.Richer skarn copper ores can be found in the contacting zones,and large scale porphyry copper ores can also been found on the border and deep part of the rock body.
