摘要
河南省南召县水洞岭铜锌矿床位于秦岭褶皱带东段的南召—刘山岩铜锌多金属成矿带内,该矿床产于早古生界二郎坪群酸性火山岩(Pz1er)内,并受水洞岭复向斜东北翼控制。通过对矿床地质特征、成矿物质来源、物理化学环境及成矿时代等方面的研究,认为成矿物质主要来自于深部物源区,成矿热液则是大气降水和岩浆水组成的混合水。矿床成因属海相火山喷流沉积-弱改造块状黄铁矿型铜锌矿床。
Shuidongling Cu - Zn deposit in the Nanzhao county of Henan province is located in the Nanzhao - Liushanyan copper and zinc polymetallie mineralizing belt of eastern Qinling fold belt. The deposit is occurred in the early Paleozoic Erlangping group acidic volcanic rocks, and controlled by the northeast wing of the Shuidongling compound syncline. It is considered that ore materials are mainly derived from source in depth, and ore -forming fluids came from mixture of meteoric and magmatic water, according to ore geology, ore material source, physical chemical environment and mineralizing time. The genesis of the deposit belongs to a marine volcanic spout sedimentary - reformation massive pyrite type Cu - Zn deposit.
