海相磷块岩占磷矿资源的74%以上,因此在成因理论的研究方面,人们多注重海相磷块岩的研究。这方面的工作早在19世纪中叶就已开始,至今已有生物成因说、化学或生物化学成因说、交代说及机械沉积说等四种主要学说。这里试图通过这四种成因学说的介绍,简述海相磷块岩成因理论的研究历史和现状,并对各家的观点作扼要的评述和提出自己一些粗浅的看法。
Phosphorite marine rocks account for more than 74% of the phosphate rock resources, so in the genesis theory, people pay more attention to marine phosphorite rock research. Work in this field began as early as the middle of the 19th century. So far, there have been four major theories of biological causes, chemical and biochemical causes, accountability and mechanical deposition. Here, we try to introduce the history and present situation of the research on the genetic theory of marine phosphogypsum through the introduction of these four causes of genesis, and give a brief commentary on the opinions of all the others and put forward some superficial opinions.
