摘要
通过归来庄金矿床隐爆角砾岩体的特征分析 ,认为归来庄隐爆角砾岩体不是隐爆 -侵入角砾岩 ,而是原地爆破生成的正常隐爆构造。结合归来庄金矿的矿床特征、矿化蚀变特征及其流体包裹体特征认为 ,归来庄金矿为一普通的隐爆角砾岩型金矿床 ,岩浆期后热液形成隐爆角砾岩体的同时形成了金矿。在其爆破与成矿过程中 ,流体经历着“升温→爆破 (沸腾 )→降温→升温→爆破(沸腾 )→降温”
Analysis of crypto-explosive breccia in Guilaizhuang Au mine reveals that the breccia is in-situ explosive breccia rather than exploded intrusion breccia. Characters of the deposit, alteration and minineralization show that it is a normal crypto-explosive breccia type Au deposit formed simultaneously with the breccia. During ore formation and explosion fluid is evolved in the way of temperature rising-explosion (boiling)-temperature falling-temperature rising-explosion(boiling)-temperature falling.
