(2003)The nature of rhythmic carbonate-rich successions such as limestone-marl alternations has been, and still is, subject to controversy. The possibility of an entirely diagenetic origin for the rhythmic calcareous alternations ...
-
(2003)Fractal theory and related developments have significantly enlightened our understanding of many natural phenomena and led to an upsurge in research efforts in many different disciplines. This has unfortunately caused some ...
-
(Федеральное государственное бюджетное образовательное учреждение высшего образования «Санкт-Петербургский горный университет», 2017)The article examines a method of forecasting strength properties and their scale effect in fissured rock mass using computational modelling with final elements method in ABAQUS software. It shows advantages of this approach ...

-
(Федеральное государственное бюджетное образовательное учреждение высшего образования «Санкт-Петербургский горный университет», 2017)Currently in Russia and the world due to the depletion of old highly productive deposits, the role of hard-torecover and unconventional hydrocarbons is increasing. Thanks to scientific and technical progress, it became ...
-
(Федеральное государственное бюджетное образовательное учреждение высшего образования «Санкт-Петербургский горный университет», 2017)Taking into consideration natural depletion of reserves of hydrocarbons in Mesozoic deposits of the majority of operated deposits of North Caucasus and for the purpose of further development of oil and gas producing industry ...
-
(2005)In the study of selective precipitate copper slag treating process, carbon powder was added into slag and stir with inertia gas, viscosity of slag reduced so as to accelerate copper deposition. Relationship between content ...
-
(Федеральное государственное автономное образовательное учреждение высшего образования «Дальневосточный федеральный университет», 2016)Underground tunneling will cause surrounding rock stress redistributing and forming rock pressure arch. Therefore, in order to strike quantitative subsidence of tunnel vault. In this paper, the influence factors of tunnel ...
-
(1990)As a result of many years of investigations, using a method that has been extensively tested in many oil and gas regions of the USSR, the author has determined the reserves of dissolved gases in the formation waters of ...
-
(2001)In order to quantify the reservoir age in Baltic Sea sediment, one sedimentary sequence from an isostatically isolated basin was subject to high-resolution AMS radiocarbon dates. Diatom analysis confirmed deposition during ...
-
(2001)The National Weather Service (NWS) produces ensemble streamflow prediction (ESP) forecasts. These forecasts are used as the basis of a Sampling Stochastic Dynamic Programming (SSDP) model to optimize reservoir operations. ...
-
(1996)A systematic study with laser ablation—ICP-MS, scanning electron microscopy and electron microprobe revealed that ∼70–95 wt% of REE (except Eu), Y, Th and U in granite rocks and crustal protoliths reside within REEYThU-rich ...
-
(2006)Although, the kinetic reactivity of a mineral surface is determined, in part, by the rates of exchange of surface-bound oxygens and protons with bulk solution, there are no elementary rate data for minerals. However, such ...
-
(2004)The resistivity of the Rb-Sr isotopic system of magmatic rocks was assayed using a fairly paradoxical approach: The examination of previously investigated metamorphosed and metasomatized rocks with disturbed isotopic ...
-
(2004)We derive an explicit formula relating a recovered 3-D seismic slowness image to the actual seismic slowness under the assumption that a tomographically complete collection of finite-frequency traveltime shifts is inverted ...
-
(2003)Inconsistencies between an object and its image delivered by tomographical methods are inevitable. Loss of information occurs during the survey through incomplete and inaccurate data sampling and may also be introduced ...
-
(Geological Society, Special Publications, 2015)
-
(1996)Success in establishing high precision crystallization ages with the U/Pb zircon method is highly dependent on the ability to isolate or remove the effects of inherited xenocrystic components or secondary lead-loss, or the ...
