摘要
申家窑金矿产于崤山地体结晶基底之中,属典型的蚀变破碎带型金矿,围岩蚀变、包裹体、同位素、微量元素等方面综合研究表明,矿床形成经历Ⅰ期高温变质热液蚀变矿化,Ⅱ期中温变质—雨水混合热液蚀变矿化,Ⅲ期低温(200℃)循环雨水热液矿化。成矿物质具深源特征。
The Shenjiayao gold deposit,being of a typical altered crushed belt type,is formed in the crystal-line basement of the Xiaoshan terrain.A comprehensive study of host rock alteration,fluid inclusion,isotope composition and trace elements indicates that the metallizing process of this type gold depositshas successively experienced followieg three important epoches 1,high temperatnre metamorphic-hypo-thermal alteration mineralization,2,medium temperature metamorphic-mixed meteoric water and hyther-mal alteration mineralization,and 3,low temperature circulation meteoric water-hydrothermal alterationmineralization.Ore-forming materials are characterized by a deep seated source feature.
