Abstract

The results of P-wave velocity measurements in the basement and sedimentary cover rocks of the submarine Vityaz Ridge and surrounding morphostructures, used for age correlation of the geological complexes, are presented. The numerical values of the seismoacoustic parameter were obtained under laboratory conditions by direct measurements of the samples collected in the area of the Central Kuril Islands. In addition, the data derived from the seismic methods in the studied region in expeditions of previous years were used. The obtained results suggest that the sedimentary cover of the Kuril Basin is of the Paleocene or Eocene age, and the interarc basin is dated as the Paleocene.

从地震声学参数看千岛群岛弧系地区地质复合体年龄相关性的可能性

摘要

给出了海底维塔兹海岭基底和沉积覆盖岩及周围形态结构的P波速度测量结果，用于地质复合体的年龄相关性。地震声学参数的数值是在实验室条件下通过直接测量在中千岛群岛地区收集的样品而获得的。此外，还使用了从以前几年的研究中所研究地区的地震方法获得的数据。所得结果表明，千岛盆地的沉积盖层是古新世或始新世，而弧间盆地的年代则是古新世。
