Abstract

Problems of the paleogeographical evolution and changes in sedimentation environment within the Indigirka River paleovalley (the East Siberian Sea) are discussed. Based on the results of geophysical and geological research and a high-resolution study of sediment cores (grain size analysis, geochemistry, macro- and micropaleontology, pollen analysis, radiocarbon dating) the development of the Holocene marine transgression has been reconstructed, sedimentation rates have been calculated, and the basic principles of changes in sedimentation processes have been established.

沉积过程与因迪吉尔卡古河谷(东西伯利亚海沿海大陆架地区)全新世的演变
摘要 讨论了因迪吉尔卡河古河谷(东西伯利亚海)内的古地理演变和沉积环境变化问题。根据地球物理和地质研究的结果以及对沉积岩芯的高分辨率研究(粒度分析、地球化学、宏观和微观古生物学、花粉分析、放射性碳测年),重建了全新世海洋断陷的发展过程,计算了沉积速率,并确定了沉积过程变化的基本原理。
