天然界硫同位素比值的变异是解决硫化物矿床成因问题的一种有力的手段,但用来研究地热活动热补给源的工作并不多见。主要原因是,当今世界上处于开发状态的水热型地热田都处于近代或现代火山区,水热活动与地下岩浆活动具有直观和确切的时空关系。另外,有些学者认为,即使是深源硫,当它通过厚厚的沉积盖层上升到地表的过程中,也将会受到严重的混染,因而掩盖了原始硫的深源性质。另一些学者则证明:在某些特殊环境中,如果
The variation of natural sulfur isotope ratio is a powerful method to solve the problem of genesis of sulfide deposits. However, it is rare to study the heat source of geothermal activity. The main reason is that the hydrothermal geothermal field under development in the world today is in a modern or modern volcanic area, and the hydrothermal activity has an intuitive and exact spatio-temporal relationship with the underground magmatism. In addition, some scholars believe that even deep-sourced sulfur will be heavily contaminated as it rises to the surface through a thick caprock, thus masking the deep-source nature of primary sulfur. Other scholars have proved: in some special circumstances, if
