Riphean magmatism and ore formation, preceding the disclosure of the Uralian Paleoocean (western slope of the Southern Urals)

open access: yesЛитосфера, 2017
The analysis of the evolution of composition and mineral occurences of the Low and Middle Riphean magma-tic rocks from the riftogenic structures of the Bashkirian anticlinorium involving of some neighboring structures from the western slope of the ...

Rift systems on Venus: An assessment of mechanical and thermal models [PDF]

open access: yes
The formation and distribution of major tectonic features on Venus are closely linked to the dominant mechanism of lithospheric heat loss. Among the most spectacular and extensive of the major tectonic features on Venus are the Chasmata, deep linear ...

Is the Suez Rift in Its Post‐Rift Phase?

open access: yesGeophysical Research Letters
Abstract Failed rifts are widely assumed to enter post‐rift tectonic quiescence after termination of intracontinental rifting, but a comprehensive understanding of their regional morphotectonics is lacking. Our quantitative, rift‐scale geomorphic analyses in the Suez Rift, an archetypal failed rift in Egypt, reveals widespread rifting

Sedimentogenesis and geodynamics in the Cretaceous-Paleogene boundary at the epoch of continental peneplanation. Article 1. Central and Eastern Eurasia

open access: yesЛитосфера, 2015
In Central and Northeast Eurasia, we describe the sedimentation and tectonic regime of a subglobal epoch of land peneplanation, which at the latest Cretaceous and at the earliest Paleogene covered all continents.

Wilson study cycles: Research relative to ocean geodynamic cycles [PDF]

open access: yes
The effects of conversion of Atlantic (rifted) margins to convergent plate boundaries; oceanic plateaus at subduction zones; continental collision and tectonic escape; southern Africa rifts; and global hot spot distribution on long term development of ...

On the differences in continental rifting at the Earth, Mars and Venus [PDF]

open access: yes
During the process of continental rifting on Earth, the lower ductile crust stretches, forming a neck, while the upper brittle crust is broken in blocks by faults, and the blocks sink down the thinned lower crust; if the stretching continues, the neck ...

Comparative planetology: Significance for terrestrial geology [PDF]

open access: yes
The crustal evolution of the terrestrial planets increase in complexity and duration with increasing size and mass of the planet. The lunar and mercurian surfaces are largely the result of intense, post-differentiation impact bombardment and subsequent ...

Early impact basins and the onset of plate tectonics [PDF]

open access: yes
The fundamental crustal dichotomy of the Earth (high and low density crust) was established nearly 4 billion years ago. Therefore, subductable crust was concentrated at the surface of the Earth very early in its history, making possible an early onset ...
