Diagenesis of the Funing Sandstones (Paleogene), Gaoji Oilfield, Subei Basin, East of China

Petroleum Science and Technology, 2014
This study deals with the diagenesis of sandstones of the Funing Formation at Gaoji Oilfield, Subei Basin, east of China. Mineralogy was determined by X-ray diffraction and scanning electron microscopy. The sandstones are lithic arokose and feldspathic litharenite, with less subarkose and sublitharenite.

The quantitative evaluation of fault sealing during the Cenozoic in Gaoyou Depression, Subei Basin

Geological Journal, 2022
The quantitative evaluation of fault sealing is conducted based on comprehensive analysis of mechanism and type analysis of fault seal, fault seal evaluation, and case study analysis. The results indicate that the properties of fault sealing are the interaction of fault order, net‐to‐gross ratio, fault activity, mud distribution on fault walls, fault ...

Discussion on recharge source of groundwater in Subei Basin

open access: yes, 2018
Analyzing and comparing the concentration of bicarbonate in groundwater and surface water, the author of this paper presumed that the release of deep CO2 causes the dead carbon in the carbon stock to be mixed into underground water, suggesting that the 14C dating method is not suitable for groundwater dating in the Subei Basin. The cycle of groundwater

Sedimentary Evolution and Transgressions of the Western Subei Basin in Eastern China since the Late Pliocene

Acta Geologica Sinica, 2019
AbstractSedimentary sequences in the Subei Basin are complex and have been affected by interactions between the ocean and rivers since the Late Pliocene, including the Yellow River, Huaihe River, and the Yangtze River. This sedimentary evolution, in particular the timing of Pleistocene transgressions, has long been a matter of controversy owing to the ...

Evidence of the transgression lake of the Subei basin during Late Cretaceous and Paleocene and its geological significance

Frontiers of Earth Science, 2008
Based on analysis of the well drilling core from Subei basin, the authors conclude that during the Late Cretaceous and Paleocene, Subei basin was linked with the sea and the deposit was affected by transgression. The cause of marine transgression may be that since Late Cretaceous and Paleocene tension power had predominated ground-stress conditions of ...

Climatic controls on water-mass chemistry in a Paleocene lacustrine setting, Subei Basin, eastern China

open access: yesGeological Society of America Bulletin
Abstract The Paleocene epoch was characterized by global climate fluctuations and major carbon-cycle perturbations. During the greenhouse climate that characterized the early Cenozoic, a short-lived late Paleocene global cooling event has been recognized from marine records. However, the response of the terrestrial system to this climate
