(Общество с ограниченной ответственностью «Георесурсы», 2018)The paper presents the results of studying rocks of the domanic horizon of the Pervomayskoe oil field represented by core material of the well 467D. In tectonic terms, this well, like the entire Pervomayskoe field, is ...
-
(1990)Information on the conditions of transport of tungsten is very important for interpreting physicochemical conditions of formation of ore bodies. Chloride and oxychloride complexes of tungsten have received much attention ...
-
(Федеральное государственное бюджетное образовательное учреждение высшего образования «Санкт-Петербургский горный университет», 2020)The audio-magnetotelluric express sounding was performed at four sections crossing the mine field of the currently not functioning Degtyarsky mine. Field measurements were carried out by a universal broadband receiver ...
-
(1997)The vertical distribution of the scattering properties of the lithosphere can be found using Bocharov's formula which describes the broadening of an incoherent pulse with distance as it propagates in a scattering medium ...
-
(2005)For better understanding the adsorption of rare earth elements (REEs) by clay minerals and its controlling factors, the experiments on adsorption of REEs in solutions with 1 g·L-1 kaolinite were performed at different ...
-
(2002)In order to clarify Al2O3 content and phase stability of aluminous CaSiO3-perovskite, high-pressure and high-temperature transformations of Ca3Al2Si3O12 garnet (grossular) were studied using a MA8-type high-pressure apparatus ...
-
(2000)The behavior of monazite concentrate reduced by carbon, especially the decomposed procedure of rare earth phosphates, was investigated by X-ray diffraction , electron probe, TG method and chemical analysis. The results ...
-
(Федеральное государственное автономное образовательное учреждение высшего образования «Дальневосточный федеральный университет», 2016)In the sedimentary coal stratum, rock stratum exhibits layered feature and has a obvious level, after the underground coal mining, overlying rock often produces separation strata along the level. However, due to the ...
-
(2001)Stability of two-dimensional stationary continental and marine ice sheets is studied using perturbations of ice sheet surface elevation and the margin position about a steady-state solution. Ice accumulation rate at the ...
-
(2002)The Ukrainian Dniepr-Donets Basin (DDB) is a Late Palaeozoic intracratonic rift basin, with sedimentary thicknesses up to 19 km, displaying the effects of salt tectonics during its entire history of formation, from Late ...
-
(2003)At least four styles of complex behavior are recorded in trace fossils: (1) Intricate, programmed behavior that is recorded in complex trace fossils, such as Spirophyton and Zoophycos. (2) Behavior that is complex in ...

STYLES OF SEDIMENTATION BENEATH SVALBARD VALLEY GLACIERS UNDER CHANGING DYNAMIC AND THERMAL REGIMES (2001)Glacier beds provide crucial information concerning past and present ice dynamics and thermal regime. In this paper we present structural and sedimentological data from four valley glaciers (Austre Lovénbreen, Midtre ...
-
(2001)In many areas of the world, the presence of shallow high velocity, highly heterogeneous layers complicate seismic imaging of deeper reflectors. Of particular economic interest are areas where potentially hydrocarbon-bearing ...
-
(2001)Using the principles of electro-osmosis, a sub-sampling technique for clay-rich sediments is introduced that produces undisturbed thin-sections from sediment cores. The fragile sample remains in the same disposable box ...

(PANGAEA, 2017-07-07)
-
(2004)This article reports the discovery of numerous subaerial exposure surfaces which occur in the ca. 2200 Ma Kuetsjärvi Sedimentary Formation (KSF) from the Pechenga Greenstone Belt, NE Fennoscandian Shield, Russia. The ...
-
(2001)In this article, we report on the results of the investigation of trace and major element contents and compositions of minerals for the representative collection of subalkaline picritic basalts from the Putorana plateau ...
-
(2001)We report the data for melt and fluid inclusions from phenocrysts of subalkaline picrite basalts and tholeiitic plateau basalts from Putorana plateau, Siberian trap province. The analyses of reheated melt inclusions from ...
