  • River inflow and salinity changes in the Caspian Sea during the last 5500 years. 
    Leroy, Suzanne A G (PANGAEA, 2018-04-06)
  • RIVER PATTERNS AND THEIR MEANING 
    Twidale C.R. (2004)
    Rivers are largely responsible for shaping the Earth's continental landscapes. River patterns, the spatial arrangements of channels in the landscape, are determined by slope and structure. At site and sector scale, channel ...
  • ROBUST SATELLITE TECHNIQUES FOR VOLCANIC AND SEISMIC HAZARDS MONITORING 
    Di Bello G.; Filizzola C.; Lacava T.; Tramutoli V.; Marchese F.; Pergola N.; Pietrapertosa C.; Piscitelli S.; Scaffidi I. (2004)
    Several satellite techniques have been proposed to monitor events related to seismic and volcanic activity. A selfadaptive approach (RAT, Robust AVHRR Techniques) has recently been proposed which seems able to recognise ...
  • ROCK BLOCKS MOTION IN LARGE-SCALE UNDERGROUND EXPLOSIONS: EXPERIMENTAL DATA 
    Kacharyan G.G.; Spivak A.A. (2001)
    The instrumental measurement results of the residual shifts and deformations of rocks massif under the action of underground nuclear explosions are presented. The main attention is paid to the problems of deformations ...
  • ROCK DILATION, NONLINEAR DEFORMATION, AND PORE PRESSURE CHANGE UNDER SHEAR 
    Hamiel Y.; Agnon A.; Lyakhovsky V. (2005)
    The dilation of rock under shear gives rise to detectable effects both in laboratory experiments and in field observations. Such effects include hardening due to reduction in pore pressure and asymmetrical distribution of ...
  • Rock failure and nonlocal elasticity theory 
    Dorovsky Vitaly N.; Vtorushin Egor V.; Romenski Evgeniy I. (Федеральное государственное бюджетное образовательное учреждение высшего образования «Сибирский государственный университет геосистем и технологий», 2017)
    The paper considers failure of a stratum within the framework of a nonlocal elasticity theory for a plastic flow. Here, the nonlocality is determined by dependence between deformation energy and metric deformation tensor ...
  • Rock failure and nonlocal elasticity theory 
    Dorovsky Vitaly N.; Vtorushin Egor V.; Romenski Evgeniy I. (Федеральное государственное бюджетное образовательное учреждение высшего образования «Сибирский государственный университет геосистем и технологий», 2017)
    The paper considers failure of a stratum within the framework of a nonlocal elasticity theory for a plastic flow. Here, the nonlocality is determined by dependence between deformation energy and metric deformation tensor ...
  • ROCK KRIGING WITH THE MICROSCOPE 
    Voytekhovsky Y.L.; Fishman M.A. (2003)
    An idea to consider rock textures from a geostatistical viewpoint is suggested. Mineral grains are coded by indicator functions. Four metrics are shown of interest for petrographic applications. The simplest one is used ...
  • ROCK MAGNETIC RECORD OF THE LAST GLACIAL-INTERGLACIAL CYCLE FROM THE KURTAK LOESS SECTION, SOUTHERN SIBERIA 
    Zhu R.X.; Sun J.M.; Matasova G.; Kazansky A.; Zykina V. (2003)
    Detailed rock magnetic investigations, grain size determination and X-ray diffraction were carried out on loess and buried soils of the last glacial-interglacial cycle from Kurtak, southern Siberia. The susceptibility and ...
  • ROCK PRESSURE DISTRIBUTION IN ZONES OF TECTONIC FAULTS 
    Rzhevskiy V.V.; Afanasenko G.V.; Davidenko B.Y. (1988)
    Tectonic faults consist of water-saturated rocks crushed and crumbled into gravel and sand fractions, thus facilitating a hydraulic connection between the water-bearing zone and all other rocks till the ground surface. ...
  • ROCK-AVALANCHE DYNAMICS: INSIGHTS FROM GRANULAR PHYSICS EXPERIMENTS 
    Friedmann S.Ju.; Taberlet N.; Losert W. (2006)
    Rock avalanches are known to behave in extraordinary ways unlike other landslides, and their deposits in part reflect their unusual physical behavior. Recent experiments in granular physics suggest that many phenomena and ...
  • ROCK-FORMING MINERALS AND PETROGENESIS OF NICKEL-BEARING NORITE- DIORITE INTRUSIONS OF VORONEZH CRYSTALLINE MASSIF 
    Pereslavtsev A.V.; Slyunyayev A.A. (1992)
    A detailed investigation was made of the typomorphic and chemical characteristics of the rock-forming minerals in norite-diorite intrusions in the Voronezh crystalline massif. The rocks of the intrusions are characterised ...
  • ROCK-WATER MODEL AS A BASE FOR PREDICTING THE CHEMICAL COMPOSITION OF NATURAL CRUSTAL WATERS 
    Ryzhenko B.N.; Krainov S.R. (2003)
    The computer-assisted physicochemical modeling of hydrogeochemical processes that occur in systems of sedimentary and crystalline rocks with water has been done for the following variables: the weight ratio of the reacted ...
  • RODENTS AND CLIMATE: A NEW MODEL FOR ESTIMATING PAST TEMPERATURES 
    Legendre S.; Maridet O.; Escarguel G.; Montuire S. (2005)
    Based on the high correlation between species richness in sigmodontine rodents and temperatures, we propose a new model in order to quantify past climates. Because of the close phylogenetic relationship and the tooth ...
  • RODENTS FROM THE EARLY PALEOGENE DZHYLGA LOCALITIES IN SOUTHERN KAZAKHSTAN 
    Averianov A.; Martin T. (2001)
