新疆哈密市沙泉子铜矿地质特征及矿床成因初探

Geological Features and Oregenesis of Xiaquanzi Copper Deposit in Hami City

沙泉子铜矿床为次火山热液沉积型铜铁矿,对该矿区域背景、矿区特征、矿体特征、成矿物质来源以及成矿机制研究表明,其早期成矿与火山喷发作用密切相关,后期与岩浆热液侵入相关联,良好的地质条件为铜铁矿的形成提供了物质来源、热源、运移通道、储矿空间。

The Shaquanzi copper is avolcanic hydrothermal sedimentary copper deposit. The study on the mine area settings, orebody features, metallogenic source and mineralization mechanism shows that the early mineralization was closely related with the volcano eruption, whereas the late mineralization was associated with the magmatic hydrothermal invasion. Favorite geological conditions provided material sources, heat source, migration path and reservation space for the formation of the copper deposit.
