(2003)Studies based on repeat levelling performed in the city of Tallinn show local earth surface deformations in the area of ancient valleys buried under quaternary sediments. Until 1964, the highest rate of sinking (up to 30 ...

VERTICAL RUGGEDNESS OF THE RELIEF AND PROSPECTS OF OIL AND GAS POTENTIAL IN THE WESTERN BARENTS SEA (2003)Морфоструктурное изучение западной части Баренцева моря совместно с анализом глубин и вертикальной расчлененности рельефа позволили выделить пять типов новейших движений морфоструктур и четыре типа пограничных зон по ...
-
(IOP Publishing, 2016)The article presents the analysis of sequential use of mobile percussive-rotary drilling sets with DTH hammer and bottom-hole cleaning by foam mud in construction of vertical sections along with at Kuyumbinsky oil field. ...
-
(1997)The effect of temperature and viscosity on the kinetics of bubble growth was measured for a natural water-rich rhyolite melt. The change in volume of a natural crystal-poor calc-alkaline rhyolitic obsidian with an initial ...
-
(1990)The upward migration of hydrocarbon gases from pay strata in seismically active oil and gas regions apparently is a penetrative process that produces maximum saturation of the sorptive capacity of the rocks overlying the ...
-
(2003)The structural behavior of β-eucryptite (LiAlSiO4) has been investigated using infrared (IR) spectroscopy over a temperature range of 20 to 900 K and FT-Raman spectroscopy at room temperature. IR reflectance measurements ...
-
(1998)The functional group chemistry and coordination of AsO43--sorption complexes in ettringite [Ca6Al2(SO4)3(OH)12.26H2O] were evaluated as a function of sorption type (adsorption, coprecipitation) and pH using Raman and Fourier ...
-
(2002)Infrared (IR) and Raman spectra of leonite-type minerals, K2Me(SO4)(2).4H(2)O (Me = Mg, Mn, Fe), confirm a succession of structural phase transitions between 277 and 120 K. Because the orientation and dynamic behaviour of ...
-
(2004)Infrared reflectance, thin-film absorbance, and polarized Raman spectra were acquired from ~100 to ~4000 cm−1 from polycrystalline garnets along the pyrope (Py = Mg3Al2Si3O12)-majorite [Mj = Mg3(MgSi)Si3O12 ] join. We ...
-
(1999)The vibrational spectrum of the CaAl2B2O7 was investigated. It was shown that the vibrations of the BO3 groups are present in the region of 1400-600 cm-1, and the bands at 519 nm-1 may originate from the AlO6 vibration. ...
-
(2000)This paper presents a concept of vibroseismic monitoring for earthquake-prone areas and the testing results of the estimation of relative variations in seismic wave velocities caused by earth tides at distances of 356 and ...
-
(1998)The number of victims from volcanism and the primary cause(s) of death reported in the literature show considerable uncertainty. We present the results of investigations carried out either in contemporary accounts or in ...
-
(2017)Satellite based remote sensing of active volcanoes has been performed in various forms since 1965. Compared to “on the ground” observations it lets data to be gathered globally at regular pace for long periods of time ...
-
(2001)We present a method for the computation of time-dependent geodetic and geophysical signatures (deformation, potential and gravity changes) due to magmatic intrusions in a layered viscoelastic-gravitational medium. This ...

VISCOELASTIC RELAXATION MEASUREMENTS IN THE SYSTEM SIO2-NAALSIO4 BY PHOTON CORRELATION SPECTROSCOPY (1997)Relaxation times of longitudinal strain for five supercooled liquids along the join SiO 2 (qz)-NaAlSiO 4 (ne) including the compositions of albite (ab), ab 50 jd 50 , jadeite (jd), jd 66 ne 33 , and jd 33 ne 66 were measured ...
