四川省峨边县脚马营铅锌矿地质特征及找矿潜力

Geological characteristics and prospecting potential of the Jiaomaying Pb-Zn deposit in Ebian County,Sichuan Province

四川省峨边县脚马营铅锌矿位于康滇地轴东缘之凉山拗陷带北段,处于扬子地台西缘铅锌矿聚集区的北部。矿区圈定了多个视极化率异常,化探异常与重砂异常重合较好,具有良好的成矿地质条件。矿体主要产于寒武系下统麦地坪组中,层控特征明显,属沉积—改造型铅锌矿。初步认为脚马营铅锌矿区找矿潜力较好。

The Jiaomaying Pb-Zn deposit in Ebian County,Sichuan Province is located in the northern section of Liangshan depression belt on the eastern margin of Kangdian axis,and in the northern part of the accumulation area of Pb-Zn deposits on the western margin of Yangzi platform.Several apparent polarizability anomalies have been delineated in the mine area,and the geochemical anomaly and heavy sand anomaly coincide well,so it has good metallogenic geological conditions.The ore body mainly occurs in Maidiping Formation of the Lower Cambrian,which belongs to the sedimentation-reformed Pb-Zn deposit with obvious stratabound characteristics.It is preliminarily considered that the Jiaomaying Pb-Zn deposit has good prospecting potential.
