| 摘 要： | 海沟金矿床的围岩为燕山早期中酸性花岗岩体—海沟岩体,受北东向、近东西向断裂构造控制,矿化深度约1～3 km,成矿流体主要源于岩浆,成矿物质源于上地幔,成矿温度范围为119～420℃。矿化岩石为石英脉,构造片理化带（绢云石英千糜岩）、片理化闪长玢岩脉、含金石英脉构成了海沟金矿床＂三位一体＂的成矿标志和找矿标志。矿床虽然经过多次勘查,但仍有较大找矿潜力,根据成矿条件和地质工作程度,优选出5个找矿远景区。

| Abstract: | The wall rock of Haigou gold deposit is Early Yanshan acidic granitic rock-Haigou rock body,controlled by fracture structure,strike NE-nearly EW.The mineralization depth 1~ 3km,the metallogenetic fluid originated from magma,metallogenic material derived from upper mantle,ore-forming temperature 119~420？C.The mineralize rock are quartz vein.The tectonic schistosity zone（sericite quartz phyllonite）,schistosity diorite porphyrite veins,and the gold-quartz veins constitute the Haigou gold deposit,which formed the ore-forming,prospecting criteria.Although deposit undergone with much exploration,there are still better prospecting potential.Based on the metallogenic conditions and degree of geological studied,determined 5 prospecting areas. |
