河南省周庄铅锌银矿床地质特征及其矿床成因分析

Geological characteristics and genesis of Zhouzhuang lead zinc silver deposit in Henan Province

河南省周庄铅锌银矿床位于北秦岭造山带东段二郎坪地体内,矿脉赋存于二郎坪群地层,严格受垂直或大角度交于区域构造的次级构造控制,呈或北东、或近东西、或近南北走向。地质特征、地球化学地质特征研究表明,周庄铅锌银矿属于在造山过程中形成的中低温热液脉型矿床。

The Zhouzhuang Pb-Zn-Ag deposit in Henan Province is located in the Erlangping terrane of the eastern segment of the North Qinling orogenic belt.The veins are hosted in the Erlangping Group strata and are strictly controlled by the secondary structures intersecting the regional structures vertically or at large angles.They are in NE,E-W or N-S strikes.Geological and geochemical characteristics show that the Zhouzhuang Pb-Zn-Ag deposit belongs to the medium-low temperature hydrothermal vein type deposit formed in the orogenic process.
