对沉积矿床的成因问题历来存在着不同的说法。例如,磷块岩的成因问题开始时与海洋生物作用相联系,然后与细菌作用、磷酸钙从海水中的化学沉淀、生物化学反映、火山作用过程、成岩过程以及沉积物沉积后的反复冲洗作用相联系。近年来在一系列努力下,恢复了微生物假说。该假说的原
There has always been a different view of the causes of sedimentary deposits. For example, the genesis of phosphogrons was initially linked to the role of marine organisms and then to bacterial interactions, chemical precipitation of calcium phosphate from seawater, biochemical reactions, volcanism, diagenesis and repeated rinsing after deposition of sediments related. In recent years, a series of efforts restored the microbial hypothesis. The original of this hypothesis
