Morphological analysis of stylolites for paleostress estimation in limestones surrounding the Andra Underground Research Laboratory site [PDF]

International Journal of Rock Mechanics and Mining Sciences, 2013
We develop and test a methodology to infer paleostress from the morphology of stylolites within borehole cores. This non-destructive method is based on the analysis of the stylolite trace along the outer cylindrical surface of the cores.

Post-Miocene tectonics of the Northern Calcareous Alps [PDF]

Scientific Reports, 2022
The Late Cretaceous orogeny followed by the Eocene collision of the Adriatic with the European plate dissected the Northern Calcareous Alps (NCA) by a number of well-studied strike-slip fault systems accommodating N-S shortening and E-W stretching ...

Stress dynamics associated with the Nyasa / Malawi rift: Implication for the present-day East African Rift System dynamics [PDF]

Heliyon, 2023
The Nyasa/Malawi rift (NMR), known for its poor magma and notable seismic activity, has sparked a debate regarding its stress kinematics. It is on one hand viewed as a transform fault, while on other hand as a rift structure characterized by normal ...

Bed parallel slip and paleostress analysis of the Kodki fault zone, Kachchh, Western India

Quaternary Science Advances, 2023
The Kodki fault zone comprises a unique fault system along the Median High (MH) zone in the Kachchh Mainland Uplift (KMU) region of the Kachchh Rift Basin (KRB).

Middle Pleistocene tectonic events around the SE Aegean Sea: Insights from magnetostratigraphy, (U–Th)/He zircon dating, and fault kinematics in the Datça Graben (SW Türkiye) [PDF]

Scientific Reports
This study constrains the stratigraphy, age, and tectono-sedimentary evolution of the Datça Graben (southwestern Turkey) through integrated magnetostratigraphy, zircon (U-Th)/He geochronology, sedimentological analysis, and fault kinematic studies.

Influence of preexisting structures on the variation of neotectonic paleostress orientation in an area of the Southeastern Brazilian Margin

Brazilian Journal of Geology, 2021
The Southeastern Brazilian Margin presents a NE-SW-striking structural framework, which is characteristic of the Neoproterozoic Ribeira Belt. Other important structural trends along the area are associated with E-W and NW-SE-striking structures, being ...

Paleostress Analysis from Calcite Twins at the Longshan Dome (Central Hunan, South China): Mesozoic Mega-Fold Superimposition in the Reworked Continent

Geosciences, 2021
It is generally accepted that during the Mesozoic NE−NNE-trending folds overprinted E−W-trending folds to form the Longshan dome in the central South China continent, although the interference map does not tell the relative ages of the fold sets.

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.

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.
