吉林香炉碗子金矿床稳定同位素特征及矿床成因

STABLE ISOTOPIC CHARACTERS AND ORIGIN OF THE XIANGLUWANZI GOLD DEPOSIT,JILIN

香炉子金矿床产于中生代形成的火山隐爆角砾岩体之中，隐爆角砾岩体受ＥＷ向脆—韧性剪切带所控制。在论述矿床稳定同位素特征，分析成矿物质来源的基础上，结合矿床地质特征和有关地质资料，提出香炉碗子金矿床的形成，是与燕山期岩浆活动有直接联系的古老基底重熔再造的、中低温。

The Xiangluwanzi gold deposit occurs in the cryptoexplosive volcanic breccia formed in Mesozoic,which was controlled by the EW brittle ductile shear zone.Based upon the stable isotopic characters and analysing to the ore forming source materials,combined with the geological characters,it is concluded that the gold deposit was a post volcanism hydrothermal type gold deposit with middle-low temperature,remelted and reformed by ancient basement directly related to the Yenshanian magmatism.
