Lithosphere, 2022 The tectonic deformation of the outer Indo-Burman Ranges (i.e., Chittagong Tripura Fold Belt, CTFB) is associated with the oblique convergence of Indo-Burmese plates since the latest Miocene.

Paleostress Analysis of Atlantic Crustal Extension in the Quebec Appalachians [PDF]
The Journal of Geology, 2006 Abstract A paleostress analysis using normal fault slip data and Jurassic dike trends has been conducted in the Quebec and New England Appalachians. Stress tensor analysis of fault slip by a numerical inversion method has distinguished homogeneous and directionally consistent E‐W‐ and NW‐SE‐oriented extensional stress regimes in the Quebec Appalachians

Minerals, 2022 This research assessed stress regimes and fields in eastern Iran using fault-slip data and the tectonic events associated with these changes. Our stress analysis of the brittle structures in the Shekarab Mountains revealed significant changes in stress regimes from the late Cretaceous to the Quaternary.

Control of pre-existing fabric in fracture formation, reactivation and vein emplacement under variable fluid pressure conditions: an example from Archean greenstone belt, India [PDF]
Solid Earth, 2020 Most of the upper crustal fluid flows are strongly influenced by the pre-existing fractures/foliations in the rocks under a certain state of tectonic stress and fluid pressure condition.

Paleostress analysis of the volcanic margins of Yemen [PDF]
Arabian Journal of Geosciences, 2010 The western part of Yemen is largely covered by Tertiary volcanics and is bounded by volcanic margins to the west (Red Sea) and the south (Gulf of Aden). The oligo-miocene evolution of Yemen results from the interaction between the emplacement of the Afar plume, the opening of the Red Sea and the westward propagation of the Gulf of Aden.

Modeling the growth of stylolites in sedimentary rocks [PDF]
, 2012 [1] Stylolites are ubiquitous pressure solution seams found in sedimentary rocks. Their morphology is shown to follow two self-affine regimes. Analyzing the scaling properties of their height over their average direction shows that (1) at small scale ...

Paleostress Analysis in Brittle Structures of the Camaquã Copper Mines
Revista Brasileira de Geociências, 2012 Fault planes with striae and kinematic indicators from the Camaqua Copper Mines, Cacapava do Sul (Brazil), were analyzed through graphical methods and structural geology software in order to determine the stress-field orientation for the numerous tectonic events that affected the region, and in this way determine the paleostress fields.

TwinCalc: A multitool for calcite twinning based stress analysis
Applied Computing and Geosciences, 2020 Calcite twining has been used and proved repeatedly as a viable stress analysis tool during past several decades, however a comprehensive multitool for stress analysis has been missing.

Frontal belt curvature and oblique ramp development at an obliquely collided irregular margin : geometry and kinematics of the NW Taiwan fold-thrust belt [PDF]
, 2003 Combined structural and tectonic analyses demonstrate that the NW Foothills of the Taiwan collision belt constitute mainly an asymmetric “primary arc” type fold-thrust belt.
