海洋微生物腐烂后沉积形成磷酸盐。
The phosphate was deposited by the decay of Marine microorganisms.
SFCW由于使所有水流不断与土壤层、砾石层和豆石层反复接触，生成难溶性磷酸盐的几率大大高于SFCW，能够比SFCW更加显著地促进磷沉积。
W-SFCW system, which provides more interaction surfaces for wastewater to react with soil, oval stone and small-sized stone layers, showed higher chances to form insoluble phosphate than SFCW.
在凝缩剖面中，化石和有机物磷酸盐和海绿石质物质相对于几乎不含化石的快速沉积剖面而言，都趋向于被凝缩。
In condensed sections, fossils and organic, phosphatic and glauconitic material tend to be concentrated compared with rapidly deposited sections that contain few fossils.
