汶上县兴化寺金矿地质特征

Geological Characteristics and Origin Study on Xinghuasi Gold Deposit in Wenshang County

摘要:

对兴化寺金矿床地质特征、矿物组合、金的赋存状态、金的矿源层进行了研究 ,探讨了变质作用、岩浆作用及构造作用对金的活化、迁移、富集的影响。其矿化与绿岩带、韧性剪切带及燕山期岩浆活动关系密切。属多期次热液充填蚀变成因。

Abstract:

Through study on geological characteristics, gold source bed, mineral combination and gold occurrence in Xinghuasi gold deposit, effects of metamorphism, magmatism and tectonic process to gold activating, transferring and concentration are studied in this paper. It is regarded that mineralization has a close relation with greenschist belt, ductile shear belt and Yanshan period magmatic movement, and the deposit belongs to polyphasic thermal filling-alteration type.
