  • 湘东北雁林寺金矿床地质特征及找矿标志……陈冲,郭爱民,孙骥,陆文
  • 摘 要:雁林寺金矿床位于扬子板块东南缘、江南古陆中段的湘东北地区。经地表及深部探矿工程揭露控制,雁林寺金矿区共圈定金矿体38条(工业矿体15条,低品位矿体23条)。金矿体主要赋存于新元古界冷家溪群黄浒洞组第一岩性段和黄浒洞组第二岩性段底部北东向韧性剪切带中,主要呈北北东—北东向展布,倾向北西西—北西,呈层状—似层状顺层产出。矿体与围岩产状基本一致,但形成明显晚于围岩。矿石主要由含金石英脉及其内部、边部的含金蚀变板(砂)岩组成,二者往往相伴产出。根据野外观察,结合控矿因素与矿化富集规律,确定了雁林寺金矿床的找矿标志,为矿山开展深边部找矿工作提供了依据。

    Geologicalcharacteristics and prospecting signs of the Yanlinsi Gold Deposit in thenortheast of Hunan Province……Chen Chong,Guo Aimin,SunJi,Lu Wen

    AbstractThe Yanlinsi Gold Deposit is located in northeast part of Hunan Provincethat sits on the southeast edge of the Yangtze plate and the middle section ofthe Jiangnan ancient land.After the control was revealed by the surface anddeep exploration projects,38 gold ore bodies were delineated in the Yanlinsimining area(15 are industrial ore bodies and 23 are low-grade ore bodies).Themain ore bodies mainly occur in the NE-trending ductile shear zones of thefirst lithologic section and the bottom of the second lithologic section of theHuanghudong Formation,the Neopro-terozoic Lengjiaxi Group.The orebodies,inlayered or layer-like occurrence,are mainly NNE or NE distributed and have theNWW or NW tendency.The orebodies are basically in the same occurrence with thesurrounding rocks,but the formation was significantly later.The orebodies aremainly composed of auriferous quartz veins and its internal and marginalalluvial altered plate (sand) rocks,which often accompany each other inoutput.Based on field observations and analysis of ore-controlling factors andmineralization enrichment laws,the prospecting signs of the Yanlinsi GoldDeposit were determined,providing basis for the mine to carry out deep andperipheral mine prospecting work.
