(2005)Род Pristiograptus в странах Балтии встречается в интервале cyphus - ultimus - parultimus. Максимальное видовое разнообразие пристиограптид наблюдается в верхневенлокских зонах nassa - ludensis. В этом интервале присутствуют ...
-
(2003)The analytic resource assessment method, called ACCESS (Analytic Cell-based Continuous Energy Spreadsheet System), was developed to calculate estimates of petroleum resources for the geologic assessment model, called ...
-
(2002)The probabilistic river stage forecast (PRSF) specifies a sequence of exceedance functions {n:n=1,...,N} such that n(hn)=P(Hn>hn), where Hn is the river stage at time instance tn, and P stands for probability. The probabilistic ...
-
(2002)Prior to excavation, any point in a rock mass is subjected to stress, which has to be considered in the overall stress distribution after the excavation work is completed. Over the past three decades, empirical, analytical, ...
-
(2001)Problems connected with rock burst hazard have been considered. Mathematical model of rock burst hazard has been developed. The model makes it possible to calculate risks of rock bursts. In this case, geodynamic hazard can ...
-
(2004)We have developed a method for the Bayesian location of seismic sequences in 3D heterogeneous velocity models. The method is based on a Bayesian algorithm for single earthquake location. Joint location of seismic sequences ...
-
(2004)We applied Sambridge's Neighbourhood Algorithm (NA) to degree-8 fundamental mode Love and Rayleigh wave phase velocity maps between 40 and 150 s to find models of radial anisotropy in the upper 220 km of the mantle. The ...
-
(2004)The presence of radial anisotropy in the upper mantle, transition zone and top of the lower mantle is investigated by applying a model space search technique to Rayleigh and Love wave phase velocity models. Probability ...
-
(2001)A portion of a sedimentary basin is subdivided conceptually into hexagons of equal area. The area of each hexagon is equal to the minimum area an oil field should have to be commercial. Hexagons can be 'full' of oil or ...
-
(1990)To ascertain the possible generation depth of the El'dzhurta granite magma, we determined the strontium-isotope composition of granite and plagioclase from different levels in the pluton. For this purpose, granite samples ...
-
(2004)Study of the impact of charged particles, ultra-violet radiation with different wave lengths, and other space energy sources on the abiogenic synthesis of biologically significant compounds (BSC) is closely related to ...
-
(1997)Seeded fluorite crystal growth experiments were performed at three different ionic strengths, using a constant addition method and NaNO3 as background electrolyte. By varying the fluorite seed concentration, growth rates ...
-
(2004)Scapolite is usually known as a mineral of metamorphic rocks and skarns. Primary-magmatic scapolite is extremely rare. This article presents data on the primary scapolite first detected in rare metal pegmatites. The ...
-
(1989)The results of our thermobarogeochemical study of rocks of the anorthosite complex discussed here allow us not only to estimate the parameters of the fluid directly in inclusions from different minerals, but also to trace ...
-
(2001)Process of crushing the brittle layer has been considered. Mathematical models are used for calculating the deformations and stresses. Simple calculations are provided due to the use of method of finite elements and a ...
-
(2000)Results of macroseismic and instrumental investigations were summarized to formulate the basic requirements on an intensity scale. Several empirical relations are quoted to show that these requirements are indispensable. ...
-
(2001)Opportunities for development of getting the coal with opencast method in Russian Federation have been considered. Efficiency of further development is largely connected with internal problems in Russian Federation. Part ...
-
(1989)We present analyses which suggest that single or multiple water leaches of low-salinity fluid inclusions are suspect and their application to chemical geothermometry is likely to give erroneous results.Leaching experiments ...
-
(2002)Problems of perfecting zonal stratigraphic scales based on the paleontologic evidence are discussed. In all the diversity of biostratigraphic units we operate with, there are two basic types-biostratigraphic zones lacking ...
