(2000)High-resolution, in situ X-ray reflectivity measurements were made of the calcite (104)-water interface in calcite-saturated aqueous solutions at pH values ranging from 6.8 to 12.1 and low PCO2. The X-ray reflectivity data, ...
-
(2003)Many theoretical models predict that arrested dykes may generate major grabens at rift-zone surfaces. Arrested dyke tips in eroded rift zones, however, are normally not associated with major grabens or normal faults that ...
-
(2003)The atomic and electronic structure of mineral surfaces affects many environmentally important processes such as adsorption phenomena. They are however rarely considered relevant to dissimilatory bacterial reduction of ...
-
(2001)Hydrologists and water resources managers who work in areas that receive a significant portion of the annual precipitation in the form of snowfall rely on good approximates of snow accumulation in order to assess snowpack ...

(Федеральное государственное бюджетное образовательное учреждение высшего образования «Санкт-Петербургский государственный университет», 2015)Слабо сцементированные кварцевые арениты саблинской свиты слагают маломощный песчаный покров, который был образован в кембрии на мелководном северном обрамлении эпиконтинентального Московского палеобассейна. С помощью ...

(1996)Surface charge and UO22+ adsorption were measured on a clay-sized, subsurface mineral isolate whose mineralogy was dominated by a ferrogenous beidellite. Experiments were performed in batch at 25°C with N2(g) atmosphere ...
-
(2001)Many organic compounds depress the surface tension of water relative to their aqueous concentration. These surface-active organic solutes have been shown to cause water flow in unsaturated porous media. Flow in these systems ...
-
(2002)Focuses on the uses of mineral crystals. Importance of physical properties of minerals on the diagnostic uses of mineral; Composition and crystal structure of minerals; Process of biomineralization by organisms. INSET: ...
-
(2004)For several hours following the Chicxulub impact, the entire Earth was bathed with intense infrared radiation from ballistically reentering ejecta. The global heat pulse would have killed unsheltered organisms directly and ...
-
(2001)We studied the effect of extreme acceleration and change in acceleration, or jerk, on bacteria to determine if they could survive impact ejection from a planet. Computer simulations based on the spallation model [H.J. ...
-
(PANGAEA, 1996-04-27)Distribution and composition of suspended matter in the western Black Sea is examined in relation to influence of river run-off and eutrophication. Changes in suspended matter concentration and composition within the studied ...

-
(PANGAEA, 2000-06-15)A comparative estimation of particulate organic matter concentration in seawater in various regions of the Barents Sea was carried out on the basis of materials collected by authors in August-September 1997. It is shown ...

(PANGAEA, 2000-11-06)
-
(2000)Of the world's great rivers, the Ob and Yenisey rank among the largest suppliers of fresh water and among the smallest suppliers of suspended sediment to the coastal ocean. Sediment in the middle reaches of the rivers is ...
-
(2002)Natural resources, e.g., metals, industrial minerals, water, and soil, are the essential basis for our economy and well-being. We have to know where these raw materials come from and how they are mined. Sustainable development ...

-
(1998)Carbonate-phtanite sediments of Bogambir suite (Uppermost Precambrian, Northern Nuratau Mountains, Uzbekistan) are to be discriminated from Ordovician and Silurian in the imbricated Variscian structure of Bogambir range. ...
-
(PANGAEA, 2016-05-13)Bathymetry based on data recorded during M84-2 between 26.02.2011 and 02.04.2011 in the Black Sea. The aim of the cruise was to investigate the gas hydrate distribution in sediments of the Black Sea by using several coring ...
