(2000)The 1989 IUGS classification of the igneous rocks for the high-Mg and picritic volcanic rocks has been revised. Instead of an 18 wt % MgO minimum limit being applied for all high-Mg and picritic volcanic rocks, that is now ...

-
(2003)The discrimination between chemical and thermal heterogeneity in the Earth's mantle remains one of the most important and challenging questions to be answered by observational and theoretical geophysics. To answer this ...
-
(2000)The alunite supergroup consists of more than 40 minerals with the general formula DG 3( T O4)2(OH,H2O)6, wherein D represents cations with a coordination number greater or equal to 9, and G and T represent sites with ...

(2004)Johillerite from a fumarole in the North Breach of the Great Fissure Tolbachik eruption (GFTE), Kamchatka Peninsula, Russia, monoclinic, a 6.7520(14), b 12.739(3), c 11.068(2) Angstrom, beta 100.37(3), V 936.4(2) Angstrom(3), ...
-
(2003)Detailed regional body wave tomographic inversion of the Western Pacific region has been performed using P and S travel times from common sources and receivers, with a joint inversion in terms of bulk-sound and shear ...
-
(2002)1] We use mantle and inner core sensitive normal modes to invert for laterally varying mantle models and a transversely isotropic inner core. To obtain an inner core model that is compatible with long-period mode and ...
-
JOINT INVERSION OF NORMAL MODE AND BODY WAVE DATA FOR INNER CORE ANISOTROPY 2. POSSIBLE COMPLEXITIES (2002)In this study we focus on inner core sensitive body wave data to investigate lateral and radial heterogeneity within the inner core. Normal mode data are used to constrain a global model and to monitor if complexities ...
-
(2002)The method of Surface Nuclear Magnetic Resonance (SNMR) provides a very new technology to directly determine subsurface water distribution. The microscopic magnetization of water molecules is used to derive water content ...
-
(2004)We develop a quantitative methodology to interpret jointly in‐situ transient‐pressure and dc resistivity measurements acquired in a hypothetical water injection experiment, with the goal of displacing oil in a hydrocarbon‐bearing ...
-
(2003)The goal of this work was to study a contaminated soil due to a gasoline spill produced by fissures in a concrete purge chamber located along a gas transmission line. A monitoring well drilled 16 m down gradient from the ...
-
(2001)Characterization of 'critical flaws' that initiate into systematic joints is essential for understanding the process of fracturing in sedimentary rocks. In this study, advantage is taken of the well-developed surface ...
-
(2001)Over 18,000 joint orientations were measured from a spectrum of lithologies of various ages at natural exposures in the Central Kyzyl Kum region. For each exposure, we plotted joint orientation diagrams and identified local ...
-
(2001)July mean temperature and annual precipipation during the last 9900 cal. yr BP were recon structed from pollen assemblages preserved in a sediment core from northern Finland. Quantitative recon structions were performed ...
-
(2002)Structural features and composition of Jurassic deposits in the Kafan tectonic block that is located in the southeastern part of the Lesser Caucasus are considered. Three carbonate members bearing foraminifers are distinguished ...
-
(2004)The study is devoted to Jurassic gastropods of the Central and Central Chernozem regions of Russia. Thanks to the exact locality data on the collected material, the stratigraphic ranges of many species were refined. Several ...
