Paleostress Analysis in Brittle Structures of the Camaquã Copper Mines

open access: yesRevista 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.

A contribution to better understanding of structural characteristics and tectonic phases of the Boč region, Periadriatic Fault Zone

open access: yesGeologija, 2016
The aim of this study was to determine properties of the tectonic contact between Permian/Mesozoic limestones and less competent Miocene clastites on the northeastern foothill of the Boč Mt.

TwinCalc: A multitool for calcite twinning based stress analysis

open access: yesApplied 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.

Mesozoic/cenozoic strike-slip tectonics in the catarinense shield and its correlation with structures associated with the continental rift in southeastern Brazil

open access: yesAnais da Academia Brasileira de Ciências, 2022
Structural studies carried out on mesoscopic scale of planar and linear brittle structures from quarries in Precambrian rocks of the central-southern portion of the Catarinense Shield led to a characterization of four main fault directions: NE-SW, NW-SE ...

Geological characteristics of the boundary between Bolkardağı-Bozkır Units and the Ulukışla Basin and the structural evolution of the region, Central Taurides, Turkey

open access: yesBulletin of the Mineral Research and Exploration, 2021
The character of the boundary between the tectonic units in the Central Taurides and the Ulukışla Basin is controversial. The contact has been accepted as discordant or tectonic contact by different researchers.

A new approach for paleostress analysis from kink bands: application of fault-slip methods [PDF]

open access: yes, 1999
Optimal and nonoptimal methods of fault-slip analysis are tested on the simple type of kink bands by treating these structures as if they were striated faults.

Reactivation of minor faults in a blind active fault area: A case study of the aftershock area of the 2000 Western Tottori Earthquake, Japan

open access: yesJournal of Asian Earth Sciences: X, 2021
The 2000 Western Tottori Earthquake (Mw 6.6, Mjma 7.3) in Japan occurred in an area where no active faults are known to exist. We examined the distribution, occurrence, paleostress field, and K–Ar ages of minor faults in the aftershock region of this ...

From Oblique Thrust to Strike-Slip Fault: Progressive Stages of an Accretionary Wedge Development [PDF]

open access: yesLithosphere
Accretionary wedges of orogenic belts develop differently based on the direction of thrusting, which can be perpendicular to oblique to the belt. In the case of oblique thrusting, stress partitioning occurs, which dissects the accretionary wedge, changes
