广东玉水铜矿及外围地球化学特征及找矿远景分析

Geochemical Characteristics And Prospecting Prospects Of Yushui Copper Deposit And Its Surrounding Areas In Guangdong

广东玉水铜矿具有矿石品位富、矿体厚度较大、矿体分布范围小的特点,矿床成因争议很大。虽然经历的多次找矿工作,但均没有获得实质性进展。本次工作通过对各种成矿元素、微量元素的分析,探讨玉水铜矿区及外围岩石地球化学特征,为下一步的找矿工作提供依据。玉水铜矿及外围地表填图岩石样品分析结果表明,矿体上方断层岩的Zn、Mn具有明显异常,成矿后的断层作为早期层状矿体的探针,能有效示踪深部的隐伏矿体。

The Yushui copper deposit in Guangdong Province is characterized by rich ore grade,large ore body thickness and small ore body distribution.The genesis of the deposit is controversial.Although many times of prospecting work have been experienced,no substantial progress has been made.Through the analysis of various ore-forming elements and trace elements,this work discussed the petrochemical characteristics of Yushui copper mine area and its surrounding rocks,providing a basis for the next prospecting work.The analysis results of Yushui copper mine and surrounding surface mapping rock samples show that the Zn and Mn of fault rocks above the ore body are obviously abnormal,and the fault after mineralization can effectively trace the hidden ore body in the deep as a probe of the early layered ore body.
