【摘要】 老街子矿床属中低温次火山热液银铅共生矿床,构造蚀变控制矿体形态、规模,F3与F4断裂夹持部位中的火山岩原生、次生裂隙是主要容矿构造。由于多次构造的变动及多期次成岩,使成矿作用多次叠加。更多还原

【Abstract】 The Laojiezi Pb deposit belongs to the type of middle-low T subvol canic hydrothermal Ag-Pb paragenetic deposit.The form and scale of orebody are controlled by the structural alteration.The main ore-bearing structure is the original and secondary fissures of volcanic rock in the area between F3 and F4.The metallogenesis has the characteristics of multistage superimpo sition because of the multistage structual activities and diagenetic processes.更多还原
