Polyphase Tectonic Evolution of the Puerto Rico‐Virgin Islands Microplate Revealed by Fault‐Slip Data and Stress Inversions

Geochemistry, Geophysics, Geosystems
The northeastern Caribbean plate boundary (NCPB) includes the Puerto Rico‐Virgin Islands (PRVI) microplate that is bounded by oblique subduction zones in the Muertos and Puerto Rico Trenches, and by the Mona Rift, and the Anegada Passage rifts.

Morphometric and structural diagnosis of fault reactivation in the Cenozoic: a case study of the Blumenau-Soledade Lineament in southern Brazil

Brazilian Journal of Geology, 2021
The hypothesis that geomorphometric parameters and structural-geological features are diagnostic of reactivation of the Blumenau-Soledade Lineament in central-western Santa Catarina, Brazil was tested by confronting data on asymmetry, elongation ...

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

Anais 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 ...

Insights into the Paleostress Analysis of Heterogeneous Fault-Slip Data by Comparing Different Methodologies: The Case of the Voltri Massif in the Ligurian Alps (NW Italy)

Applied Sciences, 2022
One of the most critical stages in fault-slip data stress analysis is separating the fault data into homogeneous subsets and selecting a suitable analysis method for each subset.

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 ...

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.

Genetic Mechanism of Lower-Order Faults in Shale Formations in Rift Basins

Geofluids, 2023
The distribution of lower-order faults affects the development of oil and gas and the distribution of remaining oil, which is also the key to the development of fault block reservoirs in eastern China.

Fingerprinting stress: stylolite and calcite twinning paleopiezometry revealing the complexity of progressive stress patterns during folding-the case of the Monte Nero anticline in the Apennines, Italy [PDF]

, 2016
In this study we show for the first time how quantitative stress estimates can be derived by combining calcite twinning and stylolite roughness stress fingerprinting techniques in a fold-and-thrust belt.
