複雜硫鹽類礦物和較稀少的硫化物礦物在自然界分布的數量是比較少的,並且其中有很多礦物因彼此性質近似而難於鑑定,這就使得人們對它們的研究存在一定的困難,並使之成為礦物學研究方面的薄弱環節。因之,關於闡述這方面問題已有的文獻是比較少,研究這些方面問題的中國材料也極其缺乏。 Complex sulfur salt minerals and sparse sulfide minerals in the natural distribution of the number is relatively small, and many of them due to the nature of each other and difficult to identify the nature of the minerals, which makes the people of their research there are some difficulties and make Become the weak link in mineralogy research. Because of this, there are only a few articles on elaborating this issue, and there is a great shortage of Chinese materials on these issues.
