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

open access: yesGeochemistry, 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 ...

Shock wave propagation characteristics of aluminum‐containing explosive in corrugated steel‐lined tunnel

open access: yesDeep Underground Science and Engineering, EarlyView.
Aluminum‐enhanced afterburning renders AE explosives more hazardous than conventional ones. Corrugated steel linings reduce far‐field AE blast overpressure by ~50% through wave reflection and dissipation. The developed model accurately predicts peak pressure (<10% error) and arrival time (<3% error), supporting protective design.

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

open access: yesCommunications 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.

Mechanism and disaster control new technology of strong ground pressure manifestation in ultra‐large mining face

open access: yesDeep Underground Science and Engineering, EarlyView.
In response to the problem of strong mining pressure manifestation along the goaf roadway in a thick coal seam mining area, this study uses a new type of combined blasting roof cutting technology to effectively control the manifestation and deformation of mining pressure along the goaf roadway.

Regarding the discussion about the banded magnetic anomalies of the oceans

open access: yesГеофизический 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

open access: yesFrontiers 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 ...

Dynamic geo‐hydrogeological monitoring‐driven situational awareness for real‐time floor water inrush risk prediction in deep mining

open access: yesDeep Underground Science and Engineering, EarlyView.
The fused data extracted from the distributed monitoring system as the data basis, combined with dynamic geological data, are imported into a deep learning model. As the geological conditions of mining and excavation change, the risk of water inrush at the working face is retrieved in real time.

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

open access: yesГеодинамика 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).
