Mechanism for stress abnormality and rock burst in variation zone of roof-stratum thickness

open access: yesYantu gongcheng xuebao, 2023
The roof stratum structure is one of the main factors affecting coal burst, and the coal burst is also easily induced in the variation zone of roof-stratum thickness. This phenomenon is gradually severe in deep mining areas in Inner Mongolia.

The Central European Permian Basins; Rheological and structural controls on basin history and on inter-basin connectivity [PDF]

open access: yes, 2014
We analyse the relative importance of the major crustal-scale fault zones and crustal architecture in controlling basin formation, deformation and the structural connections between basins. The North and South Permian Basins of Central Europe are usually

THE CURRENT STATE OF CRUSTAL STRESSES IN THE CAUCASUS ACCORDING TO THE UNIFIED CATALOGUE OF EARTHQUAKE FOCAL MECHANISMS

open access: yesГеодинамика и тектонофизика, 2020
The current state of crustal stresses in the Caucasus and adjacent territories has been reconstructed. Stress inversion was performed by the cataclastic analysis of earthquake focal mechanisms considered as seismological strain indicators.

Upper plate tectonic stress state may influence interseismic coupling on subduction megathrusts

open access: yes, 2012
We document a correlation between along-strike variation in interseismic coupling depth on subduction interfaces, and the upper plate tectonic stress state in New Zealand, Vanuatu, and southwest Japan.

A new species of Lonchidiidae (Hybodontiformes) from the Late Jurassic of Brazil (Aliança Formation, Jatobá Basin)

open access: yesThe Anatomical Record, EarlyView.
Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...
