Abstract

In southeastern Khabarovsk krai, in the basin of the Tumnin River, the foraminifera complex containing the characteristic species Ammosiphonia beresoviensis (Bulatova), represented by exclusively agglutinated shells, is revealed for the first time in sections of Albian deposits. In terms of composition and structure, the complex is closest to the associations widespread in the Albian in the Arctic paleogeographic zone. It differs from the coeval assemblages of Sakhalin and Japan in the absence of warm-water species.

哈巴罗夫斯克边疆区阿穆尔河下游早期白垩纪有孔虫的发现

摘要

在图姆宁河盆地的哈巴罗夫斯克（Khabarovsk）东南部，首次在阿拉伯地区沉积物中发现有孔虫复合体，其中包含有特征性物种beresoviensis（Bulatova）的特征是仅由凝集的贝壳代表。就组成和结构而言，该复合体最接近在北极古地理区域的阿尔比亚地区广泛分布的联系。在没有温水物种的情况下，它与萨哈林岛和日本的古代组合不同。
