中庄－泽上金矿床隶属于牟平－乳山成矿带，区域成矿条件有利。该矿区已发现27条矿脉3条金矿体，围岩多发生绢英岩化、褐铁矿化、碳酸盐化，矿床类型为石英脉或蚀变岩＋石英脉型。矿脉严格受断裂构造控制，北东东向断裂构造是该区找矿的突出标志，红褐色网脉状、褐色块状铁帽为该区找矿的直接标志。应加强对1、6号矿脉的综合研究和其他矿脉的查证工作。
中莊－澤上金礦床隸屬于牟平－乳山成礦帶，區域成礦條件有利。該礦區已髮現27條礦脈3條金礦體，圍巖多髮生絹英巖化、褐鐵礦化、碳痠鹽化，礦床類型為石英脈或蝕變巖＋石英脈型。礦脈嚴格受斷裂構造控製，北東東嚮斷裂構造是該區找礦的突齣標誌，紅褐色網脈狀、褐色塊狀鐵帽為該區找礦的直接標誌。應加彊對1、6號礦脈的綜閤研究和其他礦脈的查證工作。
중장－택상금광상대속우모평－유산성광대，구역성광조건유리。해광구이발현27조광맥3조금광체，위암다발생견영암화、갈철광화、탄산염화，광상류형위석영맥혹식변암＋석영맥형。광맥엄격수단렬구조공제，북동동향단렬구조시해구조광적돌출표지，홍갈색망맥상、갈색괴상철모위해구조광적직접표지。응가강대1、6호광맥적종합연구화기타광맥적사증공작。
Zhongzhuang and ZeShang gold deposit belongs to Muping–Rushan metallogenic belt with regionally favorable metallogenic conditions.The mining area has found 3 gold ore body in 27 veins, and occurred in surrounding rock are seric-itization, limonitization, carbonation.The deposits type is quartz vein or altered rock +quartz vein type.The veins are strictly controlled by the faults, and the NNE fault structure is remarkable signs of prospecting in this area, direct signs in the area are red brown stockwork, brown massive gossan ore prospecting.Comprehensive research on the No.1 or No.6 vein and the verification work of other veins should be strengthened.
