We present new age constraints for igneous rocks and ore-metasomatic formations of the gold deposits in the Akzhal-Boko-Ashalin ore zone. In terms of their ore formation, these deposits correspond mainly to the orogenic type, which generally reflects ...

The geothermal resources in mountainous areas are usually controlled by neotectonic faults. To minimize the risk in site selection for geothermal drilling, the controlling mechanism must be identified.

Paleostress field reconstruction in the Oslo region
Abstract The geodynamic history of a region is archived in its geologic record which, in turn, may reflect deformation patterns that causally can be related to certain configurations of paleostresses. In the Oslo Region, the exposed geological record ranges from Precambrian high-grade metamorphic rocks through Cambro-Silurian sedimentary rocks to ...

Mechanics of the giant radiating Mackenzie dyke swarm: A paleostress field modeling [PDF]
The 1.27 Ga Mackenzie dyke swarm of the Canadian Shield is a giant radiating dyke swarm that gradually swings in orientation from N‐S in the focal area to NW‐SE trends in peripheral areas. In this paper, we propose a new model (the “Plug” model) that accounts for the paleostress contribution to the mechanism of emplacement for the Mackenzie dyke swarm ...

Contrasting stress fields on correlating margins of the South Atlantic [PDF]
The “passiveness” of passive continental margins across the globe is currently under debate since several studies have shown that these margins may experience a variety of stress states and undergo significant vertical movement post-breakup.

Stress Field Evolution of the Southernmost Andean Cordillera From Paleostress Analysis (Argentine Tierra del Fuego) [PDF]
AbstractThe Argentine Tierra del Fuego comprises part of the roughly east‐west trending southern end of the Andean Cordillera intensely deformed since the Mesozoic. Mesostructures have been measured in Late Jurassic to Miocene rocks. Taking into account statistical criteria to provide a representative stress tensor from a fault population, this study ...

Modeling the growth of stylolites in sedimentary rocks [PDF]
[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 ...
