Stable isotopic evidence for climate and basin evolution of the Late Cretaceous Songliao basin, China

open access: yesPalaeogeography, Palaeoclimatology, Palaeoecology, 2013
Abstract Because of the need to understand the links and feedbacks of the carbon cycle during times of global greenhouse conditions numerous studies have focused on the Cretaceous climate. Much of what we know about this warm period in Earth's history comes from the study of ocean sediments recovered from both ocean drill cores and marine sediments ...

The Songliao Super Basin in northeastern China

AAPG Bulletin, 2023
Abstract With several superimposed petroleum systems and a proven reserve of 200 billion bbl of oil and 160 TCF of gas, the Songliao Basin in northeastern China is considered a super petroliferous basin. This paper outlines the basin’s tectonic units, its tectono-stratigraphy, and the essential elements of each petroleum system and ...

Sedimentary Characteristics of the Cretaceous in the Songliao Basin

Acta Geologica Sinica - English Edition, 1993
Abstract The rupture of the lithosphere in Late Jurassic brought about the eruption of basaltic magma in the Songliao Basin. The evolution of the basin in Cretaceous progressed through six stages: pre‐rift doming, extensional fracturing, fault subsidence, fault downwarping, downwarping and shringkage, resulting in the deposition of terrstrial facies ...

Late Cretaceous paleoclimate and paleoenvironment in the Songliao Basin, China

Journal of Paleolimnology, 2021
The Songliao Basin, northeast China, possesses an excellent Cretaceous lake sediment record that provides an opportunity to investigate Cretaceous terrestrial climate and environmental conditions. We measured total organic matter (TOC), aliphatic and aromatic hydrocarbons, marine biomarkers and δ13C and δD compositions of individual n-alkanes in ...

Chronological and Geochemical Characterisitics of Volcanic Rocks of the Yingcheng Formation in the Southern Songliao Basin: Constraints on the Early Cretaceous Evolution of the Songliao Basin

Acta Geologica Sinica - English Edition, 2020
AbstractThe discoveries of oil and gas reservoirs in the volcanic rocks of the Songliao Basin (SB) have attracted the attention of many researchers. However, the lack of studies on the genesis of the volcanic rocks has led to different opinions being presented for the genesis of the SB.
