Abstract

The mineral composition of the heavy subfraction from surface sediments of the Sea of Okhotsk has been studied using two detailed profiles (the Magadan-Kuril Islands and the Shantar Islands-Central part of the Sea of Okhotsk) and data from the Sakhalin Gulf. The obtained data have been analyzed by the methods of multivariate statistics, which allowed us to identify the main associations of heavy minerals that show regional differences in the mineral complexes of marine sediments. A significant effect of the solid discharge of the Amur River on sedimentation processes has been recorded. Two large regional sources of clastic material, the Amur-Sakhalin and Kuril-Kamchatka supplying provinces, had a major influence on the formation of the mineral composition of the sediments.

鄂霍次克海沉积物的矿物成分作为供应来源和碎屑物质分布特征的指标

摘要

鄂霍次克海表层沉积物重组分的矿物成分已使用两个详细的剖面图（马加丹-库里尔群岛和鄂霍次克海的尚塔尔群岛-中部）和萨哈林海湾的数据进行了研究。所获得的数据已通过多元统计方法进行了分析，这使我们能够识别出重矿物的主要关联，这些重关联显示了海洋沉积物矿物复合物中的区域差异。记录了阿穆尔河固体排放对沉积过程的显着影响。阿穆尔—萨哈林岛和千岛—堪察加半岛这两个提供大量碎屑的区域性资源，对沉积物矿物成分的形成产生了重大影响。
