摘要: 通过对茶尖岭矿区M28异常分布区的硫同位素分析结果及一些元素比值、微量元素及数值等特征的综合分析，结合有关岩矿鉴定等资料，认为M28异常分布区二叠系下统范家屯组地层岩石属于沉积成因.该地层在沉积成岩时，有机碳吸附了大量金属元素，以致范家屯组地层中银多金属具有较高的初始含量，为该异常区银多金属的成矿奠定了物质基础.

Abstract: Based on the result of sulfur isotope analysis, as well as element ratio and microelement data of the M28 anomaly area in the Chajianling orefield, with also lithologic and mineral identification, it is concluded that the Lower Permian Fanjiatun Formation in the M28 anomaly area belongs to sediment genesis. During the sedimentation and diagenesis of the strata, organic carbon adsorbed amount of metal elements, causing the high primary content of Ag-polymetal in the Fanjiatun Formation. It provides the material basis for the Ag-polymetal mineralization of the anomaly area.
