摘　　要：松梁铅锌矿床是明显受构造控制的热液型铅锌矿床,在川滇黔铅锌成矿域内具有一定的代表性。在讨论矿床地质特征的基础上,文章选择该矿床有代表性的号矿体,研究其构造原生晕轴向分带序列。研究结果表明:号矿体构造原生晕综合轴向分带序列为:Li-P-Cu-Ba-Cd-Ga-Zn-V-Ag-Mn-Ge→U-Sn-Th-Be-ΣREE-Pb-Bi→Cs-In-Ta-Tl-Ti-Co-Nb-Mo-W→Zr-Ni-Sr-Rb-Hf-Cr;号矿体构造原生晕轴向分带序列和地球化学参数在轴向上的变化规律均表明其构造原生晕结构比较复杂,反映号矿体成矿作用经历了多期多阶段,同时预测号矿体深部延深较好或有隐伏矿体存在的可能性。The Songliang Pb-Zn deposit is a hydrothermal Pb-Zn deposit which is dominantly controlled by structure and can considered as a representative for PbZn metallogenic area among Sichuan,Yunnan and Guizhou Provinces.Based on the discussion about the geological characteristics,the paper has selected the representative No.I orebody of this deposit to study the axial zonality sequence of tectonic primary halos.The results have shown that the axial zonality sequence of tectonic primary halos of No.I orebody can be...
