1·What does the terrigenous sediment consist of?
陆源沉积物是由什么组成的?
2·The distribution pattern is also strongly affected by the sediment type, and radiolarian abundance and diversity decrease with the increase of grain size and terrigenous material input.
沉积物类型极大地影响着放射虫的分布,放射虫的丰度和分异度明显地随粒度的增大和陆源物质含量的增加而减小。
3·The main sediments are made up of terrigenous clastic deposits. Other resedimented clastic constituents are: ooid, fossil clasts, plant clasts and glauconite, etc.
沉积物主要由陆源碎屑组成,其它的再沉积碎屑组份有鲕粒、化石碎屑、植物碎屑和海绿石等。
4·And every lithological member is composed of the lower gypsiferous salt bed and the upper terrigenous clastic rock, which belongs to the lacustrine sediment.
该组可划分为三个岩性段,每个岩性段均由下部膏盐层、上部陆源碎屑岩组成,均属湖泊沉积。
5·There is a close relation between the terrigenous clastic rock and the plate tectonics.
陆源碎屑岩特征与板块构造性质有着密切关系。
