The making of pure quartzose sand in continental interiors: Paraná River (Brazil and Argentina)
ABSTRACT As part of a comprehensive project on sedimentary processes in South America, this study focuses on sediment generation in the intracratonic Paraná Basin and monitors the evolution of sand composition along the Paraná River from central Brazil to the Río de la Plata estuary in Argentina.

The mechanical resistance of saturated stones [PDF]
This paper aims at investigating the effect of the presence of water on the mechanical resistance of stones. The presence of water, connected to the intrinsic properties of the stone (mineralogical composition, fabric, texture, etc.) and to the ...

Strain patterns, décollement and incipient sagducted greenstone terrains in the Archaean Dharwar craton (south India) [PDF]
The Archaean Dharwar craton is characterized by two greenstone successions: the > 3 Ga Sargur Group and the 3.0-2.5 Ga Dharwar Supergroup. Examples of both successions are described from the region of Jayachamarajapura where they are also distinguished ...

Applying Karst Hydrology Concepts to Anthropogenic Subsurface Systems and Mine Water Management
Due to the pronounced similarities between natural karst systems and mine workings, we consider mine workings as man‐made karst and present the concept of ‘anthropogenic karst’. ABSTRACT Mine water management is a permanent challenge in post‐mining areas where drainage adits play a crucial role for the regulation of water levels within partially ...

Mineralogy and Formation of a Platinum Placer Deposit, Southern South Island, New Zealand
Placer platinum group minerals (PGM), with subordinate detrital gold, have been concentrated in Pleistocene coastal sands near the present Foveaux Strait shoreline. This study characterises the PGM in what is New Zealand's only identified PGM deposit.

Contact metamorphism in the Malashan dome, North Himalayan gneiss domes, southern Tibet: An example of shallow extensional tectonics in the Tethys Himalaya [PDF]
Combined petrographic, structural and geochronological study of the Malashan dome, one of the North Himalayan gneiss domes, reveals that it is cored by a Miocene granite, the Malashan granite, that intruded into the Jurassic sedimentary rocks of Tethys ...
