据苏联和其它国家的连续地震剖面调查和深海钻探资料,进行了沙茨基海隆沉积层结构的分析,探讨了岩体顶面的4个主要地震组合和海隆基底结构的构造略图。业已查明,地震组合Б的沉积体,在布局上和南部岩体基底的山脊看来都具有古断裂带的特征,主要北东向展布。对时间剖面的声波图分析,可以查明斜坡过程不但参与了组合Б的形成,同时也划分出现代构造活化区。
Based on the continuous seismic section surveys and deep-sea drilling data of the Soviet Union and other countries, the Schatki seamounts sediment structure analysis was carried out and the structure of the top four major seismic groups and the base structure of the seamounts were discussed. It has been ascertained that the sediments of the seismic assemblage Б have the characteristics of paleo-fractures in the layout and on the ridges of the basement of the southern rock mass, mainly distributed in the NE direction. The acoustic profile analysis of the time profile shows that the slope process not only participates in the formation of the combination Б, but also divides the modern tectonic activation zone.
