阳山大坪银铅多金属矿地质特征与成矿分析

Geological characteristics and metallogenic analysis of Pb Polymetallic Deposit of Daping,Yangshan country

阳山大坪银铅多金属矿地表及浅部表现为岩浆热液型的成矿类型,通过对其地球化学特征、矿化蚀变特征、矿体特征及成矿控矿特征分析研究,认为岩浆热液成矿类型不是阳山大坪矿床的主矿体,主矿体为深部隐伏岩体接触带附近的矽卡岩型矿体。成矿类型的确定为后期的勘查提供了找矿方向。

The shallow ore body of Daping Pb-Zn polymetallic deposit in Yangshan county is the magmatic-hydrothermal type.Based on studying onthe geochemical characteristics,mineralization alteration features,ore body characteristics and orecontrolling features,we consider that the main metallogenic type of the Daping Ag-Pb-Zn polymetallic deposit in Yangshan county is not a magmatic-hydrothermal metallogenic deposit.However,the mian ore body is the skarn-type ore body,which is located near contact zone of a deep concealed pluton.The determination of metallogenic type will provide the prospecting direction for the later exploration.
