在自然界中,硫的分布非常广泛。硫可呈气态、液态和固态等多种形式存在于地球的各层圈中。目前的研究表明,各种硫化物的形成条件可由硫同位素组成的变化反映出来,从这个意义上说,硫同位素是一个很好的示踪剂,可以根据矿物的硫同位素组成判断矿物的原始形成条件。由于硫的稳定同位素组成的“指纹”特征,硫同位素示踪技术已被广泛地应用到环境领域中的硫循环和硫源解析等研
In nature, the distribution of sulfur is very extensive. Sulfur can be gaseous, liquid and solid forms exist in various layers of the earth circle. Current research shows that the formation of various sulfides can be reflected by changes in the composition of sulfur isotopes. In this sense, sulfur isotopes are a good tracer that can be used to determine the mineral’s original formation based on the sulfur isotope composition of the minerals condition. Sulfur isotope tracing techniques have been widely applied to the research on sulfur cycle and sulfur source analysis in the field of the environment due to the “fingerprinting” feature of sulfur stable isotope composition
