A multilayer model of time dependent deformation following an earthquake on a strike-slip fault [PDF]

open access: yes
A multilayer model of the Earth to calculate finite element of time dependent deformation and stress following an earthquake on a strike slip fault is discussed. The model involves shear properties of an elastic upper lithosphere, a standard viscoelastic

DESTRUCTION OF THE LITHOSPHERE: FAULTBLOCK DIVISIBILITY AND ITS TECTONOPHYSICAL REGULARITIES

open access: yesГеодинамика и тектонофизика, 2015
A new concept is proposed concerning the origin and inception of ‘initial’ faults and formation of large blocks as a result of cooling of the Archaean lithosphere, during which Benard cells had formed (Fig. 5).

Plume‐Induced Subduction Initiation: Single‐Slab or Multi‐Slab Subduction?

open access: yesGeochemistry, Geophysics, Geosystems, 2020
Initiation of subduction following the impingement of a hot buoyant mantle plume is one of the few scenarios that allow breaking the lithosphere and recycling a stagnant lid without requiring any preexisting weak zones.

GEOLOGICAL CONSEQUENCES OF AMORPHIZATION OF THE LITHOSPHERE AND UPPER MANTLE STRUCTURES CAUSED BY HYDROGEN DEGASSING

open access: yesГеодинамика и тектонофизика, 2015
Formation of the geological medium boundaries and patterns is specific, but such specific features have not been fully considered yet. No consideration is given to the nature of periodic variations of various parameters of the geological medium from the ...

Lithospheric processes [PDF]

open access: yes, 1997
This is the final report of a three-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The main objective was to improve understanding of the origin and evolution of the Earth`s lithosphere by studying selected processes, such as deformation and magmatic intrusion during crustal extension ...

Interaction of mantle convection with the lithosphere and the origin of kimberlites

open access: yesГеофизический журнал, 2013
Thermobarometry of xenolites/xenocrysts from 39 kimberlites of Eurasia, Africa, and North America demonstrates that the deepest xenolites, as well as all the other, are exhumed from the depleted lithosphere implying in agreement with petrologic and ...

Twinning Strains in Synfolding Calcite, Proterozoic Sinian System, China

open access: yesGeosciences, 2018
Synfolding calcite was precipitated between layers of Neoproterozoic sandy dolomite and striated parallel to the fold axis of an open anticline with a shallow plunge during folding. The fold had limb dips of 45° and plunged 20° to the south.

Lithospheric processes [PDF]

open access: yes, 2000
The authors used geophysical, geochemical, and numerical modeling to study selected problems related to Earth's lithosphere. We interpreted seismic waves to better characterize the thickness and properties of the crust and lithosphere. In the southwestern US and Tien Shari, crust of high elevation is dynamically supported above buoyant mantle.

Open Access GNSS Data for Studies of the Lithosphere

open access: yesGeochemistry, Geophysics, Geosystems
Various types of Global Navigation Satellite System (GNSS) data are used for a wide range of applications. When modeled correctly, millimeter precision daily GNSS position time‐series yield velocities and other derived products that can be used for ...

Assessment of deep electrical conductivity features of Northern Victoria Land (Antarctica) under other geophysical constraints

open access: yesAnnals of Geophysics, 2000
The lithospheric and crustal structure of the Victoria Land continental block (Antarctica) has been studied by geological and geophysical surveys. Among them magnetovariational investigations (MV) have been addressed to highlight the deep electrical ...
