| 中文摘要:现代矿床学研究表明，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S同位素来源可将形成一个矿床的过程看作是多个总体的混合或叠加，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。笔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，定量研究了S同位素来源的问题，这一问题的解决对于研究成矿物质来源和成矿机理具有重要的意义。 |

| Mixed Total Screening for Sulfur Isotope |

| Abstract:The research on modern economic geology indicates that most ore deposits are characterized by multi-source, multi-stage and multi-genesis. Quantitative research of sulfur isotope source is a difficult problem that has long puzzled geochemists. The formation process of an ore deposit can therefore be regarded as the mixture or the superposition of quite a few totals, which can be described by a mathematical model of mixed total screening. In the study of middle and lower Yangtze valley and Dongpo orefield in Hunan Province, the authors successfully applied the mathematical model of mixed total screening, quantitatively solved the problem of sulfur isotope source and ore material source, and found out the ore-forming mechanism. These achievements are very valuable. |
