摘要
永平热水塘铅锌多金属矿体呈脉状、条带状产于侏罗系上统坝注路组构造破碎褪色蚀变带中.矿体受层位及岩性、断层破碎带、层间构造等因素控矿.矿床赋存于张扭性-压扭性转换的沉积环境,构造-岩浆热流对矿源层富化改造,在流体、热液和盐卤水作用下,形成沉积岩容矿的热液脉型铅锌多金属矿床.
Abstract
Ore bodies of the Reshuitang lead-zinc polymetallic deposit in Yongping are in vein type or banded,occurring in the fractured faded alteration zone of the Upper Jurassic Bazhulu Formation,and controlled by factors such as stratum layer and lithology,fault fracture zone and interlayer structures.The deposit is a hydrothermal vein type lead-zinc polymetallic deposit hosted in sedimentary rocks,which was formed by superposition of the ore source layer by tectonic-magmatic fluids,under the joint action of hydrothermal fluid and brine in the environment of tension torsion to compression torsion transformation.
