一硫同位素方法广泛应用于金属硫化物矿床研究,如探讨成矿物质的来源,指示成矿作用的物理化学条件,划分矿床类型和指导找矿。其中热液流体的全硫同位素组成(δ~(34)S_(∑ ))是重要参数之一。但过去发表的大部分研究成果主要采用简单的统计类比法,即假定硫化矿物的硫同位素组成δ~(34)S代表成矿热液的硫同位素组成δ~(34)S_(∑ ),并据各地质体δ~(34)S的统计分布,凡硫化矿物δ~(34)S变化小,且近零值的一类矿床均归之于岩浆热液成因;δ~(34)S变化大,且偏离零值的,
Sulfur isotope method is widely used in metal sulfide deposits research, such as exploring the source of ore-forming substances, indicating the physical and chemical conditions of mineralization, classification of ore deposits and guide the prospecting. The total sulfur isotopic composition (δ ~ (34) S Σ (Σ)) of hydrothermal fluids is one of the important parameters. However, most of the research results published in the past mainly adopt the simple statistical analogy, that is, the sulfur isotopic composition δ 34 S of the sulfide minerals represents the δ 16 S Σ Σ of the ore-forming hydrothermal fluids. According to the statistical distribution of δ 34 S in the geologic bodies, all the sulfide minerals δ ~ (34) S have little variation and nearly zero value belong to the genesis of the magmatic hydrothermal. The δ ~ (34) S variation Large, and deviate from zero value,
