| 摘 要： | 铁元素是地壳中丰度最高的元素之一,在海相沉积物成岩过程中起着非常重要的作用.铁元素作为海洋初级生产力的微营养元素,影响海相沉积物中有机质的输入,其在早期成岩阶段与硫化物和磷元素的耦合关系,可以促进或者降低有机质的保存;铁元素在海相沉积物早期成岩过程中可以改变孔隙水的化学性质,影响亚稳定碳酸盐矿物的保存,导致碳酸盐沉积物...

| Abstract: | Iron as one of the highest abundance elements in the crust,plays a very important role in the marine sediment diagenesis.Iron as a nutritive elements in marine primary productivity,affects the input of organic matter in marine sediments;the coupling of iron sulfide and phosphorus can promote or reduce the organic matter burial;During early diagenesis,iron in marine sediments can alter the chemical properties of the pore water,resulting in aragonite grain dissolution,thereby affecting the cementation of carb... |
