摘　　要：本文通过底苏和大梁子铅锌矿床硫铅及氢氧同位素研究,认为同生沉积成岩成矿阶段矿石硫来源于赋矿围岩或同生沉积成岩成矿阶段矿层.矿石铅主要来源于矿区地层.改造热液中的水主要来自大气降水,成矿热液属大气降水含矿热液.The paper presents the study of sulfer,lead,hydrogen and oxygen isotopes. It proposes that the source of sulfur at contemporaneous sedimentary phase is from sea-water sulfate and the source of sulfur at reenriched ore forming solution phase comes from ore-bearing strata. The source of lead of ore come from ore-bearing srtata. The water of reenriched ore forming solution comes from meteoric water and the ore forming solution belongs to meteoric hydrothermal solution.
