Geochemistry of the Görcsöny Ridge amphibolites ( Tisza Unit , SW Hungary ) and its geodynamic

The Görcsöny Ridge is part of the complicated Variscan metamorphic basement of the SW Tisza plate. It was penetrated by several wells, one of which (Baksa-2) has 1200 m of well core available for petrological examination. Amphibolite samples of this core are of two different sorts: the fi rst group contains biot ite, rutile, and garnet, while the second group contains ilmenite and is free of ga...

Late Palaeozoic Ultramafic Lavas in Yunnan, SW China, and their Geodynamic Significance

marine sequences within several orogenic belts in YunWe report petrological and geochemical data on ultramafic pillow nan, SW China (Figs 1 and 2; Fang et al., 1996). These lavas from Late Palaeozoic marine sequences in Yunnan, SW lavas have been interpreted to be oceanic plateaux or China. These lavas have >26 wt % MgO, euhedral to subhedral seamount eruptive rocks associated with mantle plume...

Diagenetic Evolution of Mudstones: Black Shales to Laminated Limestones, an Example from the Lower Jurassic of SW Britain

A Geodynamic Model of the Evolution of the Earth's Chemical Mantle Reservoirs

A dynamic 3-D spherical-shell model for the chemical evolution of the Earth’s mantle is presented. Chemical differentiation, convection, stirring, and thermal evolution constitute an inseparable dynamic system. Our model is based on the solution of the balance equations of mass, momentum, energy, angular momentum, and four sums of the number of atoms of the pairs U-Pb, U-Pb, Th-Pb, and K-Ar. Si...
