Abstract—

The characteristics of the mollusk assemblages in the Cenozoic key section at Kvachina Bay in West Kamchatka are given. Sixteen stratigraphically successive beds with mollusks, which are grouped in five horizons, are recognized in the sedimentary sequence with a total thickness of approximately 450 m. The biostratigraphic units are correlated with the regional horizons, and their age is determined in the interval of Middle Eocene–Middle Miocene. A number of specific features of the paleogeographic settings and climatic conditions are recognized.

西堪察加半岛Kvachina湾新生代关键段地层细分中的软体动物

摘要-

给出了西堪察加半岛Kvachina湾新生代关键部分的软体动物组合特征。在沉积层序中识别出16个地层上连续的含软体动物的床,这些床被划分为5个层,总厚度约为450 m。生物地层单位与区域范围相关,其年龄是在中始新世-中新世之间确定的。人们认识到了许多古地理环境和气候条件的特定特征。
