生物化学因素随着地面上植物的出现和广泛分布,大大地改变了风化作用过程,出现了生物化学影响风化壳岩石的新因素。结果使表生作用带化学元素的活化、迁移和堆积作用的强度及规模均有所增大。潮湿季节和干旱季节的周期性出现,致使植物迅速生长、死亡和堆积,即周期性产生大量有反应能力的有机物。炎热和周期性潮湿气候以及充气良好的介质有助于植物迅速发生生物化学和化学分解。由于地表水和地下水富含碳酸及其它有机酸,结果产生弱酸性介质。这种地球化学环境促进了铝硅酸盐岩石的强烈分 Biochemical Factors With the advent and widespread distribution of plants on the surface, the weathering process has been greatly altered and new biochemical factors affecting weathered crust rocks have emerged. As a result, the strength and scale of the activation, migration and accumulation of the chemical elements in epigenetic zones increased. The cyclical emergence of wet and dry seasons leads to the rapid growth, death and accumulation of plants, which produce large quantities of reactive organic compounds on a periodic basis. Hot and periodic humid climates and well aerated media help plants rapidly biochemical and chemical breakdown. As surface water and groundwater are rich in carbonic acid and other organic acids, the result is a weakly acidic medium. This geochemical environment has contributed to the strong division of aluminosilicate rocks
