| 摘 要： | 金山金矿位于招掖金矿带的中西部,该区岩性为元古代震旦期玲珑超单元九曲单元弱片麻状细粒石榴二长花岗岩和中生代燕山早期郭家岭超单元大草屋单元斑状细粒角闪黑云花岗闪长岩。断裂构造发育,规模较小。矿床成因为热液型,属小型蚀变岩型金矿,形成于玲珑岩体侵入后期,主要分布有两条矿体,长分别为112 m和370 m,斜深104 m和133 m,真厚度0.40 m和1.54 m,平均品位分别为19.68×10-6及3.67×10-6。矿体分别赋存在80 m及-15 m标高之上。根据其成因分析及深部钻孔控制,认为本区深部含矿性不大。

| Abstract: | Jinshan gold mine is located in midwest of Zhaoyuan gold ore belt.There exist fine-grained gneissic garnet adamellite from Jiuqu unit of Linglong super-unit in Sinian of Proterozoic and porphyritic fine-grained hornblende biotitic granodiorite from Dacaowu unit of Guojialing super-unit in early Yanshanian of Mesozoic.There developed faults in smaller scale.The gold deposit belongs to altered rock type,whose ore genesis is hydrothermal deposit type,which formed in late Linglong invasion.There mainly exist tw... |
