The Supra-Salt Sedimentary Sequence of the North Caspian Depression: Stratigraphy and Sedimentary History

open access: yesGeosciences
The North Caspian Basin, known for its oil and gas potential, was formed because of the evolution of the ancient Tethys Ocean and is also a result of the collision of the East European, Kazakhstania, and Siberian paleocontinents.

Continental emergence and growth on a cooling earth [PDF]

open access: yes, 1999
Isostasy considerations are connected to a 1-D model of mantle differentiation due to pressure release partial melting to obtain a model for the evolution of the relative sea level with respect to the continent during the earth secular cooling. In this

Occurrence Conditions and Hydrogeochemical Characteristics of High-Temperature Geothermal Resources in the Eastern Jiyang Depression

open access: yesYankuang ceshi
The eastern part of the Jiyang Depression possesses high-temperature geothermal resource potential due to the influence of the destruction of the North China craton, but there is a lack of systematic research on the occurrence conditions of high ...

Influencing Factors of Hydrocarbon Migration and Adjustment at the Edge of a Stable Cratonic Basin: Implications from Fluid Inclusions, Quantitative Fluorescence Techniques, and Geochemical Tracing

open access: yesEnergies
Understanding the mechanisms of hydrocarbon migration, accumulation, and alteration, particularly how evolution controls these processes, is critical for exploring lithologic hydrocarbons in reservoirs. In the complex tectonic settings of the continental
