(2000)The term ‘sequence’ was developed in stratigraphy during the forties, but the definition was fairly vague and unpractical. A much clearer and practically applicable (but diverging) definition was developed in sedimentology ...
-
(1996)Two assemblages of small mammals were identified in the Lower Miocene rocks of the Altynshokysu locality where they are confined to different stratigraphic units. The results promote more thorough correlations within the ...
-
(2001)A closed set of simultaneous equations, which takes into account the relaxation properties of a medium with an internal structure, has been developed. Research was conducted on methods to control the stress state of a rock ...
-
(1996)The Uralide orogen is a linear collisional belt formed during the Upper Paleozoic as a result of convergence between the East European Craton and outboard terranes, and accretion of intervening island arcs and obduction ...
-
(2006)Iron-57 resonant absorption Mossbauer spectroscopy was used to describe the redox relations and structural roles of Fe3+ and Fe2+ in meta-aluminosilicate glasses. Melts were formed at 1500 °C in equilibrium with air and ...
-
(1990)The structural environments of Mn2+ and Sr2+ at concentrations of 0.2–0.8 wt% in dry and hydrous silicate glasses have been studied using X-ray absorption spectroscopy (EXAFS and XANES). The environment of Mn in hydrous ...
-
(Федеральное государственное бюджетное учреждение науки Институт земной коры Сибирского отделения Российской академии наук, 2020)Oceanic core complexes are lithological assemblages of predominantly peridotites and serpentinites, located along intersections of some slow-spreading oceanic accreting rifts and fracture zones, embedded in the predominantly ...
-
(2006)The Levantine Basin in the South-eastern Mediterranean Sea is a world class site for studying the initial stages of salt tectonics driven by differential sediment load, because the Messinian evaporites are comparatively ...
-
(2000)The results of close mapping of areas of recent thrusts in the Central Tien Shan demonstrate that they are an element of intricately built shear zones. A system of conjugate diagonal faults of NW and NE strikes which are ...
-
(2004)The shear viscosities and 1 bar heat capacities of glasses and melts along the 67mol% silica isopleth in the system SiO2-Al2O3-Na2O-TiO2 have been determined in the temperature ranges 780-1140 K and 305-1090 K respectively. ...
-
(1993)The Baikal rift depression, located in southeastern Siberia, is one of the best investigated intra-continental rift structures in the world. In addition to being the site of comprehensive studies by Russian geo-scientists ...
-
(2006)Recent studies on the evolution of the Dead Sea basin have shed light on the intricate tectonic regime of the area. Combined with newly available data from Jordan, a new picture of a symmetrical deep basin is emerging. ...
-
(2003)A large amount of water is brought into the Earth’s mantle at subduction zones. Upon subduction, water is released from the subducting slab in a series of metamorphic reactions. The resulting flux into the mantle wedge ...
-
(2003)To calculate accurately the pressure interval and mineral proportions (i.e. yields) across the olivine to wadsleyite and wadsleyite to ringwoodite transformations requires a detailed knowledge of the non-ideality of Fe-Mg ...
-
(2003)Geological mapping and structural analysis of the Talas Ala Tau (Tien Shan, Kyrgyz Republic) have revealed a complex structure composed of folds with axial-plane cleavage and thrust faults verging towards the NE. The main ...
-
(2006)Determining the timing, duration and mechanism of tectonic events within an orogenic cycle, such as ocean subduction, continent-continent collision or gravitational collapse, is challenging, especially in ancient orogenic ...
-
(1997)X-ray absorption (XAS) and X-ray photoelectron spectroscopy (XPS) analysis of copper sulfide precipitated from aqueous solution at ambient temperatures reveals the existence of a metastable primitive structure that ages ...
-
(2003)The iron oxide–water interface is of interest not only in geochemical and environmental processes, but also in fields ranging from corrosion to photocatalysis. The structure of α-Fe2O3 (001) surfaces is not fully understood, ...
-
(2006)Hydrogen is a major constituent in a wide variety of minerals in the Earth’s crust. Usually H is bonded to oxygen forming H 2 O molecules or OH − groups. In rare cases, H 3 O + , H 3 O 2− and H 5 O 2+ units are also formed. ...
-
(2002)The structure of tuperssuatsiaite from the Aris phonolite in central Namibia was refined to an R index of 0.075 for 905 observed reflections [I > 2σ(I)] obtained with a four-circle X-ray diffractometer. Tuperssuatsiaite ...
