Geological link between fluid inclusions, dilatant microcracks, and paleostress field
Journal of Geophysical Research: Solid Earth, 1990Seismic investigations using three‐component instruments have demonstrated shear wave splitting in widely different geological and tectonic environments. Shear wave analysis suggests that the inferred anisotropy can best be explained if the rocks contain distributions of subparallel, subvertical, fluid‐filled microfractures which are aligned according ...

Salt dominated sedimentary basins are economically important, because they can have a high hydrocarbon potential. We used the Subhercynian Basin in northern Germany as a natural laboratory to analyse the evolution of piercing and non-piercing salt structures.

Abstract The Paleo-Mesoproterozoic Zhongtiao aulacogen in the North China Craton and Cuddapah basin in the Indian Craton, have both been interpreted as intra-continental rift formed by a mantle plume that led to the breakup of Columbia supercontinent, but the mechanism has not been completely deciphered.

Borehole breakout studies, aligned Quaternary volcanic vents, and kinematic analysis of Quaternary faults indicate that the present‐day least horizontal stress direction (Shmin) in Kenya is aligned approximately NW‐SE and in central Sudan is nearly N–S. Limited data in eastern Ethiopia suggest a NE‐SW Shmin orientation.

Abstract We present a methodology to determine the stress field based on the analysis of 3D seismic reflection data without additional information from wells. It involves the analysis of seismic horizons that were folded before the analyzed fault system.

The measurement of crustal stress magnitude is always challenging and generally poorly constrained. This is particularly significant in active fault zones where the knowledge of stress magnitude is crucial for understanding fault mechanics during earthquakes nucleation.
