-
(2002)We report the results of thermal convection experiments in a rapidly rotating hemispherical shell with a heterogeneous heat flux at the outer boundary to model the effect of a thermally heterogeneous core-mantle boundary ...
-
(2003)The two-dimensional analysis of rotation of rigid ellipsoidal inclusions is not applicable to situations in which either the bulk deformation deviates from plane-strain or one of the principal axes of the inclusion is at ...
-
(2001)We used experiments to investigate the behaviour of rigid elliptical cylinders embedded in a viscous fluid of finite thickness, and for very small ratios (S) between shear zone width (z) and the shortest principal axis ...
-
(2001)Orogenic gold vein deposits require a particular conjunction of processes to form and be preserved, and their global distribution can be related to broad-scale, evolving tectonic processes throughout Earth history. A ...
-
(1988)The rubidium- and strontium-isotope distribution in volcanic rocks of the shoshonite-latite series of Bulgaria has never before been investigated. The Borovitsa volcanotectonic depression studied by us is underlain by rocks ...
-
(1989)The Kiya alkalic pluton lies on the western part of the Yenisey Ridge at the center of the Chernorechensk graben. It is confined to a zone of intersecting deep faults with northwest and northeast strikes. For isotopic ...
-
(1990)For the eastern part of the region, the view that amphibole-biotite granitoids should be assigned to the Amananskiy complex is not supported clearly enough by petrologic and geochemical criteria or by geochronologic isotope ...
-
(1989)There always are considerable difficulties in accurately establishing the genetic relationship between ore deposition and magmatic activity. The ore-bearing igneous complexes of the Northeast are no exception in this ...
-
(2001)When developing a physically based mathematical description of hydrological processes over natural watersheds, the modeler faces the requirement of complete spatial specification of the various hydro-geological parameters ...
-
(2002)A new method based on an extension to time-area (TA) concept is proposed for rainfall-runoff transformation in watersheds. The method uses time variable isochrones, such that the runoff hydrograph responds well to temporal ...
-
(2001)We developed and applied a simple empirical Green function method to study induced microcracks observed during hydraulic fracturing experiments in salt rock. Either unidirectional ruptures on rectangular faults or allround ...
-
(2003)A random synthesis procedure based on finite fault model is adopted for near field strong ground motion simulation in this paper. The fault plane of the source is divided into a number of sub-sources, the whole moment ...
-
(1998)We propose a new boundary integral equation method (BIEM) to model the spontaneous propagation of rupture on a planar fault embedded in a homogeneous elastic medium. The BIEM formulation is very compact and fast in ...
-
(2001)Earthquake rupture sometimes occurs on several faults, and often decelerates or terminates at fault stepovers. Factors that control the rupture processes across stepovers are important for an understanding of earthquake ...
-
(2002)The suggestion of the concept of 'scientific revolution' by Thomas Kuhn in 1962 was, in itself, a significant event in the history of science, and 'crucial' episodes or 'paradigm shifts' have come to be of special interest ...
-
(1985)The solubility of rutile has been determined in a series of compositions in the K2O-Al2O3-SiO2 system ( + Al2O3) = 0.38–0.90), and the CaO-Al2O3-SiO2 system (). Isothermal results in the KAS system at 1325°C, 1400°C, and ...
-
(2000)Fractionation of some or all of the high field strength elements (HFSE) Nb, Ta, Zr, Hf, and Ti relative to other trace elements occurs in igneous rocks from convergent margins and in the average continental crust, and is ...
-
(2003)The transition between rutile and α-PbO2 structured TiO2 (TiO2II) has been investigated at 700-1,200 °C and 4.2-9.6 GPa. Hydrothermal phase equilibrium experiments were performed in the multi-anvil apparatus to bracket the ...
