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。
海溝金礦床的圍巖為燕山早期中痠性花崗巖體—海溝巖體,受北東嚮、近東西嚮斷裂構造控製,礦化深度約1～3 km,成礦流體主要源于巖漿,成礦物質源于上地幔,成礦溫度範圍為119～420℃。礦化巖石為石英脈,構造片理化帶（絹雲石英韆糜巖）、片理化閃長玢巖脈、含金石英脈構成瞭海溝金礦床＂三位一體＂的成礦標誌和找礦標誌。礦床雖然經過多次勘查,但仍有較大找礦潛力,根據成礦條件和地質工作程度,優選齣5箇找礦遠景區。
해구금광상적위암위연산조기중산성화강암체—해구암체,수북동향、근동서향단렬구조공제,광화심도약1～3 km,성광류체주요원우암장,성광물질원우상지만,성광온도범위위119～420℃。광화암석위석영맥,구조편이화대（견운석영천미암）、편이화섬장분암맥、함금석영맥구성료해구금광상＂삼위일체＂적성광표지화조광표지。광상수연경과다차감사,단잉유교대조광잠력,근거성광조건화지질공작정도,우선출5개조광원경구。
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.
