Seismological structure of the 1.8 Ga Trans-Hudson Orogen of North America [PDF]

open access: yes, 2016
Precambrian tectonic processes are debated: what was the nature and scale of orogenic events on the younger, hotter, and more ductile Earth? Northern Hudson Bay records the Paleoproterozoic collision between the Western Churchill and Superior plates—the ∼

Rheology of the mantle and tectonics of the oceanic lithospheric plates

open access: yesIzvestiya, Russian Academy of Sciences. Physics of the Solid Earth, 2012
The modern concepts of the rheology of viscous mantle and brittle lithosphere, as well as the results of the numerical experiments on the processes in a heated layer with a viscosity dependent on pressure, temperature, and shear stress, are reviewed ...

GENETIC SOURCES AND TECTONOPHYSICAL REGULARITIES OF DIVISIBILITY OF THE LITHOSPHERE INTO BLOCKS OF VARIOUS RANKS AT DIFFERENT STAGES OF ITS FORMATION: TECTONOPHYSICAL ANALYSIS

open access: yesГеодинамика и тектонофизика, 2015
The paper presents the first tectonophysical reconstruction of initial divisibility of the protolithosphere as a result of convection in the cooling primitive mantle. Initial division of the protolithosphere into separate masses, i.e.

The westward drift of the lithosphere. A tidal ratchet? [PDF]

open access: yes, 2018
Is the westerly rotation of the lithosphere an ephemeral accidental recent phenomenon or is it a stable process of Earth’s geodynamics? The reason why the tidal drag has been questioned as the mechanism determining the lithospheric shift relative to ...

Tertiary-Quaternary subduction processes and related magmatism in the Alpine-Mediterranean region [PDF]

open access: yes, 2006
During Tertiary to Quaternary times, convergence between Eurasia and Africa resulted in a variety of collisional orogens and different styles of subduction in the Alpine-Mediterranean region.

Age relationships of rifting, subduction and plume processes on the Eastern margin of Asia

open access: yesВестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2021
Based on the comparison of petrochemical characteristics of volcanics with spatial distributions of rheological heterogeneities in the East Asian tectonosphere, new data on the mechanisms and sequence of subduction, rifting, and plume-type central ...

The Hudson Bay Lithospheric Experiment (HuBLE) : Insights into Precambrian Plate Tectonics and the Development of Mantle Keels [PDF]

open access: yes, 2015
The UK component of HuBLE was supported by Natural Environment Research Council (NERC) grant NE/F007337/1, with financial and logistical support from the Geological Survey of Canada, Canada–Nunavut Geoscience Office, SEIS-UK (the seismic node of NERC ...

Trans-lithospheric diapirism explains the presence of ultra-high pressure rocks in the European Variscides

open access: yesCommunications Earth & Environment, 2021
The classical concept of collisional orogens suggests that mountain belts form as a crustal wedge between the downgoing and overriding plates. However, this orogenic style is not compatible with the presence of (ultra-)high pressure crustal and mantle ...

ON SMALL TANGENTIAL MASS FORCES THAT MAY EXIST IN THE LITHOSPHERE. THEIR ROLE IN TECTONICS AND GEODYNAMICS

open access: yesГеодинамика и тектонофизика, 2016
The author continues to investigate additional planetary-level stresses that occur in the crust due to distributed tangential mass forces. Such forces may be related to the daily rotation of the Earth and movements of the relatively solid core relative ...

Earth's middle age [PDF]

open access: yes, 2014
This research was funded through Natural Environment Research Council (grant NE/J021822/1) and the APC was paid through the RCUK OA block grant.Earth's middle age, extending from 1.7 to 0.75 Ga, was characterized by environmental, evolutionary, and ...
