摘要
芦柴冲铅锌矿床含矿层位存在一些特殊岩石和构造,研究后认为:该铅锌矿的形成是沉积环境、火山作用、变质构造、韧性变形构造、脆性变形构造、岩浆活动多因耦合的结果。尤其是有障壁海岸的滨海沼泽—泻湖相环境和玛珥火山爆发造就达莲塘组下段的化学环境,而使其成矿受层位控制。
There are some particular rock and structure in the ore - bearing horizon of Luchaichong Pb - Zn deposit. According to the study, we think that the Pb - Zn deposit is resulted from the combination of many factors, such as, sedimentary environment, volcanism, metamorphic structure, ductile- brittle deformation structure and magmatism, etc. Especially, the metallogenesis is controlled by the horizon because the chemical environment of Daliantang Formation Lower Member is caused by the littoral marsh with barrier coast -lagoon environment and Maer volcanic eruption.
