【摘要】 现代矿床学的研究表明,绝大多数矿床的形成具有多来源、多阶段、多成因的特点。定量研究硫同位素来源的问题一直是困惑地球化学工作者的难题,我们可以将形成一个矿床的过程看作是多个总体混合或叠加,在数学上这种混合或叠加可以用混合总体筛分的数学模型来描述。作者在长江中下游地区和湖南东坡矿田中成功地应用混合总体筛分的数学模型,定量解决了硫同位素来源,解决成矿物质来源和成矿机理具有重要的意义。更多还原

【Abstract】 The research on modern economic geology indicates that most ore deposits formed with characters of multi-origin, multi-stage and multi-genesis. Quantificational research of Sulfur isotope ohgin is a difficult problem that puzzles Geochemists all along. So the formation process of an ore deposit can be taken as the mix or the superposition of multi totals, which can be described by the mathematics model of mixed total screening. In the study of mid-down Yangtze River and Dongpo ore field in Hunan province, the authors successfully applied the mathematics model of mixed total screening, quantificationally resolved the problem of Sulfur isotope origin and mineralizing matter origin, and found out the mineralizing mechanism. This is very valuable.更多还原
