(Общество с ограниченной ответственностью «Георесурсы», 2018)This article covers the main methods of geophysical well studies aimed at studying fractured zones. Examples of the results of a quantitative evaluation of fracture parameters and examples of their use when working with ...
-
(Pleiades Publishing, Ltd. (Плеадес Паблишинг, Лтд) (Род-Таун), 2010)A method for point estimation of coseismic volume deformation from amplitudes of earthquake generated changes in the water level and from the tidal sensitivity of the water level is presented. Application of this method ...
-
(1996)Observations of the dependence of elastic-wave velocities on stress in the lithosphere, ultrasonic modeling, and field experiments using controllable sources reveal that significant nonlinear elastic effects may occur in ...
-
(2005)The subject of this paper is the structural and lithologic evolution of the earth crust in the South Tien Shan region, especially during the post-collision, platform and orogenic periods of its geologic history. The author ...
-
(2004)The intercentrum of the atlas of Karenites has a dual nature. The manus retains rudimentary praepollex and postminimus. The hind limb is long, the fibula curves sigmoidally, the calcaneus has a well-developed tuber calcanei, ...
-
(1995)The reactive continuum model (Boudreau and Ruddick, 1991), the power model (Janssen, 1984; Middelburg, 1989), and the q-theory (Bosatta and Agren, 1991a) have been used to describe decomposition of organic matter; the ...
-
(1998)After removing annual variability, power spectral analyses of local atmospheric temperature from hundreds of stations and ice core records have been carried out from time scales of 10−2 to 106 yr. A clear sequence of ...
-
(Федеральное государственное бюджетное учреждение науки Институт земной коры Сибирского отделения Российской академии наук, 2019)Eastern part of the Central Taimyr belt is composed of Precambrian rocks penetrated by granites of the Snezhnaya complex (845-825 million years) and later overlain by mid-Neoproterozoic sinpostorogenic sedimentary deposits ...
-
(1999)The precision of Tl isotopic measurements by thermal ionization mass spectrometry (TIMS) is severely limited by the fact that Tl possesses only two naturally occurring isotopes, such that there is no invariant isotope ratio ...
-
(2001)Recent nonlinear dynamical systems (NDS) techniques have been developed to analyse chaotic time series data. According to NDS theory, the correlation dimension and predictable time scale are evaluated from a single observed ...
-
(1985)During the large explosions of the Bezymianny (1956), Shiveluch (1964) and Mount St. Helens (1980) volcanoes, 4.8·1012, 3.0·1012 and 8.2·1012 kg of resurgent and magmatic material were ejected respectively. The eruptions ...
-
(2001)On tilled fields runoff directions may be affected by tillage induced oriented roughness, causing runoff to flow along tillage lines instead of topographic direction. That this has an important effect on runoff and erosion ...
-
(2004)The calculation of the rheological structure in the deep seismic profile FENNIA in the central Fennoscandian Shield allows in addition the modelling of the present-day stress field and state of deformation. Seismic and ...
-
(2003)The first President's appeal on the occasion of the creation of the International Paleoentomological Society (Krakow, Poland, September 6, 2001).
-
(2003)Metagranites in the NKFMASH system require external hydration during prograde high-pressure metamorphism in order to equilibrate to ambient HP conditions by producing more siliceous muscovite. Any lack of external fluid ...
-
(1994)The stability relations of lawsonite, CaAl2Si2O7(OH)2H2O, have been investigated at pressures of 6 to 14 GPa and temperatures of 740 to ˜1150°C in a multi-anvil apparatus. Experiments used the bulk composition lawsonite+H2O ...
-
(2002)To date, the evaluation of the temperature (T) and pressure (P) of formation of natural diamond has generally relied on thermobarometry of rare polymineralic inclusions containing appropriate assemblages of minerals. The ...
-
(1997)The mineralogical and chemical characteristics of the fine-grained matrix (=<3 μm) of the unique primitive carbonaceous chondrite acfer 094 have been investigated in detail by scanning electron microscopy (sem) and analytical ...
