The onset of significant biotically enhanced terrestrial weathering would have increased the flux of lithophile nutrient elements and clay minerals to continental margins.

大量的生物出现加强了陆地上的风化作用，同时增加了亲岩营养物元素和粘土矿物向陆地边缘的输入。

This is probably the most important determining factor of edge quality.

光，也许是边缘处理最重要的元素。
