Abstract—

The late Albian–early Turonian Grebenka flora is one of the most representative mid-Cretaceous floras of Northeast Russia. However, the stratigraphic position of the Grebenka beds relative to plant-bearing deposits of similar age is still debatable. It is shown that the Salamikha volcanogenic sequence, bearing the Buor-Kemyuss plant fragments, is the most probable stratigraphic analog of the Krivorechenskaya terrigenous formation. The deposits bearing the Grebenka flora lie stratigraphically below volcanogenic deposits including the Chaun flora.

俄罗斯东北部Grebenka含植物白垩纪矿床的地层位置

摘要—

阿尔比亚晚期的突厥人格列本卡植物群是俄罗斯东北部最具代表性的白垩纪中部植物群之一。但是，Grebenka床相对于类似年龄的含植物沉积物的地层位置仍然值得商bat。结果表明，带有Buor-Kemyuss植物片段的Salamikha火山成因序列是Krivorechenskaya陆源构造最可能的地层类似物。带有Grebenka菌群的沉积物在地层上位于包括Chaun菌群的火山成因沉积物之下。
