A slab in depth: Three‐dimensional geometry and evolution of the Indo‐Australian plate

Geochemistry, Geophysics, Geosystems, 2007
Geoscientists use plate tectonics to explain many aspects of both continental evolution and evolution of the planet as a whole. The subduction of material at convergent plate boundaries forms a fundamental component to the theory of plate tectonics ...

A Global Plate Model Including Lithospheric Deformation Along Major Rifts and Orogens Since the Triassic [PDF]

, 2019
Global deep‐time plate motion models have traditionally followed a classical rigid plate approach, even though plate deformation is known to be significant.

Probability prediction of true‐triaxial compressive strength of intact rocks based on the improved PSO‐RVM model

Deep Underground Science and Engineering, EarlyView.
In this work, we propose an improved particle swarm optimization (PSO) algorithm and develop an improved PSO‐relevance vector machine (RVM) model as a substitute for traditional true‐triaxial testing. The model's high prediction accuracy was validated through comparisons with two other machine learning methods and five three‐dimensional Hoek–Brown type

Development of thermal state and plate tectonics in the North China Craton during Neoarchean–Paleoproterozoic

Communications Earth & Environment
Although the early tectonic regime of the Earth remains debated, it is generally accepted that the geodynamic system underwent a notable transition during the Neoarchean–Paleoproterozoic.

Regarding the discussion about the banded magnetic anomalies of the oceans

Геофизический журнал
The author supports the theory of plate tectonics with a plume component, pointing out the weak aspects of the arguments regarding the banded magnetic anomalies (BMA) of the ocean floor, which are the subject of discussions between supporters and ...

Diversification and biogeography of Rhacophoridae – a model testing approach

Frontiers in Ecology and Evolution, 2023
A central focus of evolutionary biology is to understand species diversity by studying how they arrived at their current geographic distributions. The biogeography of the Old World tree frogs in the family Rhacophoridae has been extensively studied ...

Horizontal mantle flow controls subduction dynamics [PDF]

, 2017
It is generally accepted that subduction is driven by downgoing-plate negative buoyancy. Yet plate age –the main control on buoyancy– exhibits little correlation with most of the present-day subduction velocities and slab dips. “West”-directed subduction

Mechanical property variation mechanisms of granite subjected to real‐time high temperatures and subsequent cooling treatment

Deep Underground Science and Engineering, EarlyView.
This study investigates the coupled thermo‐mechanical behavior of granite during heating and cooling through a combination of laboratory tests and finite element analysis. The thermal conductivity, mineral composition, mass loss rate, micro‐crack observation, and thermal fracture characteristics of granite under various temperature conditions are ...

SECULAR CHANGES IN RELATIONSHIPS BETWEEN PLATE-TECTONIC AND MANTLE-PLUME ENGENDERED PROCESSES DURING PRECAMBRIAN TIME

Геодинамика и тектонофизика, 2016
Paradoxically, the lists of “proxies” of both plate- and plume-related settings are devoid of even a mention of the high-grade metamorphic rocks (granulite, amphibolite and high-temperature eclogite facies).
