The paper presents the results of grain size analysis of bottom sediments and subsea permafrost from three cores drilled in Buor-Khaya Bay. A pronounced lithologic differentiation of the studied terrigenous deposits were revealed, as well as a wide variety of grain size and genetic types of deposits accumulated in various natural environments. The most of investigated sediments are represented by alluvial sands with wide range of size, pelletizing, and sorting rates. The accumulation of these sands was closely related to the dynamics of riverine flow, slope processes, and coastal erosion and abrasion. The fine sediment fraction is poorly sorted compared to sands. According to the dataset, the predominantly detrital nature of the sedimentary material and its continental origin have been established.

布哈瓦湾底部沉积物的粒度特征

本文介绍了在Buor-Khaya湾钻探的三个岩心的底部沉积物和海底多年冻土的粒度分析结果。揭示了被研究的陆源矿床的明显的岩性差异，以及在各种自然环境中积累的各种粒度和矿床的遗传类型。研究最多的沉积物是冲积砂，其粒度，造粒和分选速率范围很广。这些沙子的积累与河流流动，斜坡过程以及海岸侵蚀和磨损的动力学密切相关。与沙子相比，细颗粒的沉积物分类不佳。根据数据集，已经确定了沉积物的主要碎屑性及其大陆起源。
