(2002)It has recently been reported that the electron capture decay constant for 7Be varies by as much as 1.5% in different oxidic compounds of Be and that application of 400 kbar pressure to a Be(OH)2 gel increases its 7Be decay ...
-
(2002)The fact that basin inversion is possible long after the cessation of rifting indicates that at least some sedimentary basins are characterized by permanent relative weakness. This paper investigates whether the steady-state ...
-
(2001)Hydrogen isotope investigations on hydrothermal quartz reveal two H-reservoirs: (i) trapped fluid inclusions, and (ii) structurally bound water in homogenously distributed small clusters or bubbles. Varying mixing ratios ...

DOLOMITE SURFACE SPECIATION AND REACTIVITY IN AQUATIC SYSTEMS - RATES DEPEND ON SURFACE SPECIATION (1999)The surface charge of dolomite (CaMg(CO3)2) was measured as a function of pH (6.5-11.5), pCO2 (10-3.5, 0.01, and 0.96 atm) and ionic strength (0.01, 0.1, and 0.5 M NaCl) using potentiometric titrations in a limited residence ...
-
(1994)In early calcite carbonatites of the Kovdor ore deposit four morphological types of dolomite are represented. In the first type, dolomite microcrystals occur as lamellae enclosed by optically continuous calcite. In the ...
-
(2004)Repeated heating and cooling cycles appear frequently in thermomagnetic experiments used to infer the palaeomagnetic field intensity. According to the fundamental assumptions used to interpret these measurements, a remanence ...
-
(2001)The Karatau Fault System of southern Kazakstan forms a crustal-scale zone of strike-slip dominated transpressional tectonics which has undergone multiple phases and styles of deformation during a protracted history of ...
-
(2001)In ammonoids, a soft body organ (possibly a supracephalic mantle fold), extending from the conch aperture secreted aragonitic wrinkles, forming a layer on the surface of the preceding whorl. The dorsal shell wall consists ...
-
(1999)The process of 2β- decay of 130Te with the formation of 130Xe was used for the tellurium-xenon isotopic dating of tellurium-bearing minerals accompanying gold mineralization. The correlation of 130Xe diffusion characteristics ...
-
(2002)When ground-based and satellite internal magnetic field data are available they are referred to different concentric spheres outside a sphere containing all the sources. Suppose that ground-based and satellite simultaneous ...
-
(1985)Several years of research on deformational history of the Alps and their Central European foreland led to the development of new models for the driving mechanism of continental drift and intraplate tectonics. It was found ...
-
(1999)The properties of albitic melts are central to thermodynamic models for synthetic and natural granitic liquids. The authors have analyzed published phase-equilibrium and thermodynamic data for the dry fusion of high albite ...
-
(2004)The geochemical response of groundwater to external forcing is studied in a tunnel hosted in fractured gneiss near and above an artificial lake having large water level variations. Dripping waters have been monitored in ...
-
(2003)Opening-mode fractures with blunt tips and large maximum apertures are characteristic of clinker that formed by combustion alteration of siliceous mudstone. These fractures are inferred to result from pore growth and ...
-
(1988)Until now, no descriptions of duranusite in Soviet deposits have been published. We found this mineral in a mercury-antimony deposit in central Tadzhikistan, whose ores are localized in complexly-deformed clastic rocks of ...
-
(2004)Duration of the functioning of elements of the lateral paragenetic reef–evaporite systems in Cambrian and Late Jurassic has been calculated. Discrepancy between total durations of the vertical growth of barrier reefs and ...
-
(2004)The isotopic-geochronological study of the young magmatic rocks of the Tyrnyauz ore field showed that magmatism in this region terminated ~1.90–1.95 Ma ago after the emplacement of vitrophyre dikes. These dikes are not ...
-
(2000)The silicate fractions of recent pelagic sediments in the central north Pacific Ocean are dominated by eolian dust derived from central Asia. An 11 Myr sedimentary record at ODP Sites 885/886 at 44.7 degrees N, 168.3 degrees ...
-
(1999)Observations of off-plane inelastic deformation around dykes motivate consideration of models of fluid-driven crack propagation in a solid which can undergo material degradation, or damage. The application to dyke propagation ...
-
(2003)We simulate spontaneous mode II crack propagation for which the path is dynamically self-chosen. Our main interests are in the formation of the branching path under the influence of self-radiating wave stresses, and in the ...
