Is There a Speed Limit for the Thermal Steady‐State Assumption in Continental Rifts?

open access: yesGeochemistry, Geophysics, Geosystems, 2021
The lithosphere is often assumed to reside in a thermal steady‐state when quantitatively describing the temperature distribution in continental interiors and sedimentary basins, but also at active plate boundaries.

Distribution of Cambrian Source Rock Controlled by the Inherited Paleotopography on the Precambrian Basement in the Tarim Basin, NW China

open access: yesFrontiers in Earth Science, 2022
The Cambrian source rock is a key indicator that will guide future hydrocarbon explorations in ultra-deep strata. Despite its importance, the characteristics of paleotopography on the Precambrian basement and the distribution of source rocks above it ...

Reconciling plate motion and faulting at a rift-rift-rift triple junction [PDF]

open access: yesGeology
Abstract Rift-Rift-Rift triple junctions are regions where three plates interact, generating complex networks of variably oriented faults. While the geometry of the fault networks is easily constrained from their surface expression, what remains unclear is how the kinematics of faults and their interactions vary spatially, and how these ...

LONG-LIVED STRUCTURAL ENSEMBLES OF THE EAST EUROPEAN PLATFORM. Article 2. THE STRUCTURE OF THE TOP OF THE BASEMENT

open access: yesИзвестия высших учебных заведений: Геология и разведка, 2018
The basement’s top tectonics of the East European platform (EEP) has been considered on the basis of the modern mapping data. The importance of the long-lived tectonic zones that form the vortex megastructure has been justified.Their Riphean — early ...

PALEOZOIC GRANITOID MAGMATISM OF THE URALS: THE REFLECTION OF THE STAGES OF THE GEODYNAMIC AND GEOCHEMICAL EVOLUTION OF A COLLISIONAL OROGEN

open access: yesГеодинамика и тектонофизика, 2021
The Ural mobile belt is an intracontinental epioceanic orogen that has already gone through all stages of the geodynamic development. Igneous rocks formed during each stage are important indicators for understanding the evolution of this belt and ...
