Paleostress analysis from sheared dyke sets

open access: yes, 1989
It is a frequently reported feature of basement terranes that dikes intruded late in the deformation sequence become sheared parallel to the dike margins. It is proposed that such sets of sheets with internal fabrics produced by this shearing along their

Early Eocene Compressional Deformation in the Northeastern Tibetan Plateau Recorded by Magnetic Fabrics of the Longzhong Basin

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Intracontinental deformation records how early Eocene India–Asia collisional stress propagated into continental interiors. How rapidly compression reached the far field, and whether coeval Paleo‐Pacific slab dynamics contributed, remain debated. The Longzhong Basin, ∼1,900 km north of the collisional zone, provides a key test.

Emplacement Conditions and Alteration of Volcanic Deposits Inferred From Magnetic Properties of the ICDP Eger Drill Site S4 (Bažina Maar), Czechia

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Titanomagnetite in alkaline maar deposits exhibits variable syn‐ and post‐crystallization alteration linked to wet emplacement and groundwater fluctuations, which remain poorly documented. Magnetic and mineralogical analyses of lapilli, scoria, and basalt from ICDP Eger drill cores S4 and S4b (Bažina maar, western Eger Graben, Czechia) reveal ...

On the Paleostress Analysis Using Kinematic Indicators Found on an Oriented Core

open access: yesUniversal Journal of Geoscience, 2014
Paleostress analysis enables identification of stress history of a studied area. Reliable data are however necessary to get consistent results. Fault planes containing kinematic indicators have to be searched and recognized. If surface field survey is impossible, data are lacking, or deeper parts of a rock environment are being studied, boreholes can ...

Origin, Recurrent Reactivations, and Tectonic Role of Transverse Zones in Thrust‐and‐Fold Belts: The Central Southern Alps (Italy)

open access: yesTectonics, Volume 45, Issue 7, July 2026.
Abstract Transverse zones (TZs) in fold‐and‐thrust belts typically comprise strike‐slip to transpressional faults and related folds, oriented sub‐parallel to the regional shortening direction. These zones are typically associated with inherited faults or lateral stratigraphic changes, which promote strain partitioning, stress rotation, and kinematic ...

Geology, age and tectonic evolution of the Sierra Maestra Mountains, southeastern Cuba

open access: yesGeologica Acta, 2006
We summarize the available geological information on the Sierra Maestra Mountains in southeastern Cuba and report new zircon fission track and biotite Ar-Ar ages for this region. Two different and genetically unrelated volcanic arc sequences occur in the
