Late Paleocene Paleoclimate recorded in halite deposits in Subei basin ,East China

Abstract Salt deposits correspond to relatively extreme climate events. However, due to insufficient independent temperature proxies, there is a lack of paleotemperature records obtained from salt laminae deposition .The Paleocene evaporite sequence deposited in the Hongze Depression of Subei Basin provides an important terrestrial sediment ...

Discovery and significance of Cretaceous-Paleogene freshwater foraminifera in Subei-South Yellow Sea Basin

Shiyou shiyan dizhi, 2021
In previous studies, the "marine facies" fossils in the second member of Taizhou Formation and the second and fourth members of Funing Formation of the Subei-South Yellow Sea Basin were generally considered to be organisms associated with transgression and organisms that lived in saline lakes. However, after reviewing the data, this theory proved to be
