Geological factors and fracture distribution in deep and ultra-deep sandstones in Kuqa Depression, Tarim Basin, China [PDF]

Solid Earth
Deep (> 4500 m) and ultra-deep (> 6000 m) sandstone reservoirs hold great potential for hydrocarbon resources, yet complex geological challenges hinder the successful exploitation of oil and gas.

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

, 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.

Neogene to Present paleostress field in Eastern Iran (Sistan belt) and implication for regional geodynamics [PDF]

Tectonics, 2017
We conducted a stress field analysis of the northern part of the ~700 km long north-southtrending, seismically active Sistan orogenic belt of Eastern Iran formed as a result of the closure of abranch of the Neo-Tethys during the early Cenozoic. Fault kinematic data reveal drastic changes in the stressregime of Eastern Iran during the late Cenozoic, with

Asymmetric continental deformation during South Atlantic rifting along southern Brazil and Namibia [PDF]

, 2017
Plate restoration of South America and Africa to their pre-breakup position faces the problem of gaps and overlaps between the continents, an issue commonly solved with implementing intra-plate deformation zones within South America.

Temporal changes in the internal stresses and pore pressures in a large-scale submarine mass transport deposit

Progress in Earth and Planetary Science, 2018
We examined the temporal changes in the internal stresses and pore fluid pressures of a submarine mass transport deposit (MTD) in the Akkeshi Formation of the Upper Cretaceous–Paleocene Nemuro Group, eastern Hokkaido Island, Japan.

Fracture network, fluid pathways and paleostress at the Tolhuaca geothermal field

Journal of Structural Geology, 2017
Abstract In this study, we examine the fracture network of the Tolhuaca geothermal system located in the Southern Andean volcanic zone that may have acted as a pathway for migration and ascent of deep-seated fluids under the far/local stress field conditions of the area.
