(2006)Head advance due to plunge pool erosion is a common process in gullies incising resistant soils. A model of headcut retreat resulting from plunge pool erosion is developed and implemented in the channel-hillslope integrated ...
-
(2006)Although hydrogen is the most abundant element in the universe, it does not occur naturally in large quantities or high concentrations on Earth. Hydrogen must be produced from other compounds such as fossil fuels, biomass, ...
-
(2006)We investigate the effects of viscoelastic (VE) rheologies surrounding a vertically dipping prolate spheroid source during an active period of time-dependent deformation between 1995 and 2000 at Long Valley caldera. We ...
-
(2006)Some geological events occur infrequently but still have a significant impact upon reservoir characteristics. By their very nature, however, it can be difficult to properly estimate the proportions of uncommon events because ...
-
(2006)Field studies along a 30°S latitude transect of the Precordillera in NW Argentina indicate that Neogene to recent deformation caused high-angle faulting that uplifted and breached a Palaeozoic east-verging thrust stack. ...
-
(2006)The geochemistry of eclogites and garnet-amphibolites from Tso-Morari region, Ladakh, India has been investigated to characterize their protoliths on the basis of immobile elements, especially trace elements including REE. ...
-
(2006)High-pressure metamorphic terranes form when slivers of continental crust are pulled into the mantle by previously subducted oceanic lithosphere. Old, cold lithosphere subducts into the mantle at steep angles, dragging ...
-
(2006)This paper presents the results of seismic investigations on the structure of the lithosphere in the area of the Trans-European Suture Zone (TESZ) in Poland that is located between the southwestern margin of the East ...
-
(2006)Tumescence at the Three Sisters volcanic center began sometime between summer 1996 and summer 1998 and was discovered in April 2001 using interferometric synthetic aperture radar (InSAR). Swelling is centered about 5 km ...
-
(2006)This study documents the petrography and whole-rock major and trace element geochemistry of 38 samples mainly from a drill core through the entire Fedorivka layered intrusion (Korosten Pluton), as well as mineral compositions ...
-
INFLUENCE OF OXIDABILITY OF CARBONIFEROUS COALS FROM THE DOBRUDJA FOREDEEP ON VITRINITE REFLECTANCE (2006)Importance of the study of the influence of coal oxidability on vitrinite reflectance (VR) as a criterion of the quality of coals and indicator of paleogeothermal regime is shown. Overview of relevant concepts demonstrates ...
-
(2006)The distribution, age and correlation of Pleistocene sediments (1.806-0.01 Ma) is presented for an about 1200 kni long geologic cross-section that extends from the Baltic Sea to the Black Sea and crosses the eastern part ...
-
(2006)An impact crater 26.8 km in diameter, located in the northern lowlands (70.32°N, 266.45°E) at the base of the flanking slopes of the shield volcano Alba Patera, is characterized by highly unusual deposits on its southeastern ...
-
(2006)The microstructure and composition of the matrix of one carbonaceous inclusion (K1) in the Krymka LL3.1 chondrite were studied using transmission electron microscopy (TEM). K1 has previously shown an enigmatic nature and ...
-
(2006)Precambrian metalliferous conglomerates are the most important source of gold, uranium, and other metals. They concentrate no less than 30% of world gold reserves and provide 30-50% of world gold production. The metalliferous ...
-
(2006)A groundwater residence time study of the deep fluvioglacial aquifer supplying Bishkek, capital of Kyrgyzstan, has found evidence of deep infiltration of recent recharge both in the main periurban wellfield and below the ...
-
(2006)The North Pennine Orefield Alston Block has produced approximately 4 Mt Pb, 0.3 Mt Zn, 2.1 Mt fluorite, 1.5 Mt barite, 1 Mt witherite, plus a substantial amount of iron ore and copper ore from predominantly vein-hosted ...
-
(2006)The Aguablanca Ni-(Cu) sulfide deposit is hosted by a breccia pipe within a gabbro-diorite pluton. The deposit probably formed due to the disruption of a partially crystallized layered mafic complex at about 12-19 km depth ...
-
(2006)The eastern Snake River Plain in southern Idaho, western United States, is characterized by 1-2 km of Pleistocene to late Pliocene basalt overlying rhyolite caldera complexes. Cyclic variations in the chemical composition ...
-
(2006)Geologic mapping, K-Ar, and 40Ar/39Ar age determinations, supplemented by paleomagnetic measurements and geochemical data, are used to quantify the Quaternary volcanic history of the Crater Lake region in order to define ...
