文中简要地叙述了大幕山锑矿田的地质条件,详细地说明了辉锑矿、黄铁矿、重晶石中硫同位素的组成;方解石中碳、氧同位素的组成和石英中氧同位素的组成,得出了关于热液和硫、锑来源的结论:成矿热液主要来源于下渗雨水;碳来源于雨水和主岩;硫、锑来源于震旦纪海水。根据石英和方解石的氧同位素组成算出了成矿热液温度为158℃。
In this paper, the geological conditions of the Dapingshan antimony ore field are briefly described. The composition of sulfur isotopes in stibnite, pyrite and barite is described in detail. The composition of carbon and oxygen isotopes in calcite and the oxygen isotopes in quartz The conclusions are as follows: The hydrothermal fluid mainly comes from the infiltration rainwater; the carbon comes from the rainwater and the main rock; and the sulfur and antimony come from Sinian seawater. According to the oxygen isotopic composition of quartz and calcite, the temperature of the ore-forming hydrothermal solution is calculated as 158 ℃.
