摘要
尼泊尔加尼甚铅锌矿位于中尼边界线附近喜马拉雅中部加尼甚山南麓,经数十年地质勘查,基本查明拉里Ⅰ矿段矿体产状和赋存规律,该矿床以锌为主,锌品位高,矿体厚度大,沿走向连续性好,锌资源量达大型规模,属典型的密西西比河谷型层控矿床,找矿潜力较大。矿体明显受MCT推覆体内的复式褶皱控制,容矿岩石及围岩均为白云石大理岩,褶皱与白云石大理岩共同控矿,白云石大理岩是首要控矿因素,向斜构造起到成矿元素再富集的作用。
The lead-zinc deposit in Ganesh Himal of Nepal is located near the China-Nepal boundary in the south of The Ganesh Himal Mountain in the central Himalayas,after decades-a total of four geological exploration,LarryⅠore block out the occurrence of ore bodies,mainly zinc,followed by lead and silver.It is a typical Mississippi Valley type stratabound deposit with high zinc grade,large orebody thickness,good continuity along the strike and great prospecting potential.Ore body obviously controlled by MCT nappe double fold in the body,the ore rock and wall rock are dolomite marble,fold and dolomite marble ore-controlling together,dolomite marble is the primary ore-controlling factors,syncline structure and enrichment of ore-forming elements.
