磷块岩(最重要的化工原材料之一)的成因仍是一个有争议的岩性学问题。在过去150年,已流行一些假说。因为大陆上分布的磷块岩是在还未进行充分研究的古海盆、古地理和古地球化学相互制约条件中形成的,现代海洋学和现代大洋的海洋地质学未能为这些假说给出充分的理论依据。本文之目的是将这些假说与现代磷的海洋地球化学和大洋中磷块岩形成过程方面的资料进行比较。
The genesis of phosphorite, one of the most important chemical raw materials, remains a controversial lithology issue. In the past 150 years, some hypotheses have been prevalent. Because the phosphogypsum distributed on the continent was formed under the constraints of the ancient sea basin, palaeogeography and palaeogeography that have not been fully studied, the modern oceanography and oceanography of the modern ocean can not give enough for these hypotheses The theoretical basis. The purpose of this paper is to compare these hypotheses with the data of modern geochemical marine phosphorus chemistry and the formation of phosphorite in the ocean.
