Rockburst prediction based on data preprocessing and hyperband‐RNN‐DNN

Deep Underground Science and Engineering, EarlyView.
A data preprocessing workflow is proposed to address challenges in rockburst data analysis. Coupled algorithms preprocess the data set, and hyperband optimization is used to enhance RNN performance. Results show that preprocessing improves accuracy, while dense layers enhance model stability and prediction performance.

Deciphering the interplay between tectonic and climatic forces on hydrologic connectivity in the evolving landscapes

Frontiers in Water
The intricate interplay between climate and tectonics profoundly shapes landscapes over time frames surpassing 10 million years. Active tectonic processes and climatic shifts unsettle established drainage systems, instigating fragmentation or ...

Tectonic evolution of the Archaean high-grade terrain of South India [PDF]

The southern Indian shield consists of three major tectonic provinces viz., (1) Dharwar Craton, (2) Eastern Ghat Mobile Belt, and (3) Pandyan Mobile Belt. An understanding of their mutual relations is crucial for formulating crustal evolution models. The

New Permo-Carboniferous geochemical data from central Thailand: implication for a volcanic arc model [PDF]

, 1991
Current ideas and models of geotectonic reconstructions of Southeast Asia are reviewed and new data on Late Carboniferous through Middle Permian tuffites and sills from central Thailand are presented in the light of the problems of Southeast Asian ...

Tectonic evolution of the Coral Sea Basin

Journal of Geophysical Research: Solid Earth, 1979
Studies of marine magnetic anomaly data from the Coral Sea basin reveal magnetic lineations which strike N70°W almost parallel to the northern margin of the Queensland Plateau. The lineation pattern is best developed in the eastern part of the basin, and we can confidently identify a sequence of anomalies 26 (and perhaps 27) through 24 repeated about ...

Creep properties and constitutive model of diabase in deep water conveyance tunnels

Deep Underground Science and Engineering, EarlyView.
The axial and lateral creep characteristics of diabase were analyzed based on compression creep tests. The nonlinear viscoelastic‐plastic model capable of describing the whole creep process was established based on the fractional derivative and damage theories.

Regional tectonic analysis of Venus equatorial highlands and comparison with Earth-based Magellan radar images [PDF]

Research on regional tectonic analysis of Venus equatorial highlands and comparison with earth-based and Magellan radar images is presented. Over the past two years, the tectonic analysis of Venus performed centered on global properties of the planet, in

Failure characteristics and the energy criterion of rock with a through‐going joint under true‐triaxial unloading conditions: Insights from the DEM model

Deep Underground Science and Engineering, EarlyView.
The rock failure mode is significantly influenced by the contributing factors, such as the joint inclination, the initial confining pressure, and the unloading point. We found six typical rock failure modes after a large number of numerical tests. Abstract Excavation unloading damages rock masses, with preferential failure along geological defects in ...

Petroleum geological characteristics of two basin belts in southern continental margin in South China Sea

Petroleum Exploration and Development, 2017
Based on the seismic, drilling, cores and outcrops data, the formation of basins, source rocks and hydrocarbon accumulations in the southern South China Sea (SSCS) were systematically analyzed to reveal the petroleum geological features of continental ...

MEVTV study: Early tectonic evolution of Mars: Crustal dichotomy to Valles Marineris [PDF]

Several fundamental problems were addressed in the early impact, tectonic, and volcanic evolution of the martian lithosphere: (1) origin and evolution of the fundamental crustal dichotomy, including development of the highland/lowland transition zone; (2)
