Mineralization Environment Evolution and Metallogentic Model of Xiaogouli and Sanyangba Gold Deposits in Western Qinling
西秦岭小沟里金矿、三洋坝金矿位于徽成盆地西成铅锌矿田中西部。在前人研究资料的基础上,对这2个矿区的地层、构造、岩浆岩的成矿环境、演化过程进行了系统整理和分析,总结出矿床的成矿模式。矿区金矿体赋存于以绿泥绢云千枚岩为主的中泥盆统西汉水组上段(D2 x 2-3)第三岩性层中,为燕山早期的沉积变质岩浆期后热液叠加改造的变质热液矿床,成矿期经历了徽成盆地闭合、隆升、造山期,对应于秦岭造山带碰撞造山、陆内推覆剪切构造演化阶段。矿体整体上顺地层产出,并受一套…查看全部>>
Xiaogouli and Sanyangba gold deposits of western Qinling are located at the mid-west-ern of XichengPb-Zn ore-field,Huicheng Basin. Based on the previous research data,the miner-alization environment evolution of these two deposits has been analyzed and studied inthis paper systematically,including stratum,structure and granitic magma. And then,the metallogenetic model has been summarized. For these two gold deposits,the ore bodies are occurred in the up-per …查看全部>>
