(2003)The oxygen-18 signal of soil and leaf water are both recorded in heterotrophically synthesized plant stem cellulose. Presently, these signals can only be teased apart with modeling and assumptions on the nature of the ...
-
(2001)In this paper, a modern image-processing technique, the Cellular Neural Network (CNN) has been firstly applied to Bouguer anomaly map of synthetic examples and then to data from the Sivas-Divrigi Akdag region. CNN is an ...
-
(1989)The paper reports on studies that used models prepared by cementing a mixture of loose porous Lyuberets quartz sand and marshallite with an alcohol solution of BF-2 glue, then drying it with hot nitrogen. This procedure ...
-
(2002)The exact location of planetary noble gases in meteorites remains unknown but it is inferred to be closely associated with, if not precisely some portion of, the macromolecular organic material in carbonaceous chondrites ...
-
(2003)The objective-function algorithm (OFA) on the basis of hard division is presented in the paper to separate polyphase fault/slip data. The separation is made by detection of linear structures existing in the data in sigma ...
-
(1988)For the first time that fractionation of U234 and U238 can occur under certain specific conditions when uranium passes from the liquid phase to the solid. It was discovered accidentally during an investigation of the ...
-
(2004)The 3-month long eruption of Asama volcano in 1783 produced andesitic pumice falls, pyroclastic flows, lava flows, and constructed a cone. It is divided into six episodes on the basis of waxing and waning inferred from ...
-
(2006)The dinoflagellate cyst, palynofacies and foraminiferal records from the Early Eocene Figols Group of the Spanish Pyrenees exhibit major changes associated with relative sea-level fluctuations and variations in efficiency ...
-
SEQUENCE OF EARTHQUAKE GENERATION IN THE LITHOSPHERE OF THE SOUTHERN HALF OF THE KURILE ISLAND ARC (1989)We investigated the structure and sequence of earthquake generation in a seismic zone in the southern half of the Kurile island arc. The zone is about 150 km wide and about 1000 km long. The investigation was based on an ...
-
(1998)Analysis of local and regional stratigraphic relationships has permitted the assessment of the nature of tectonic structures and their distribution throughout the observed history of Venus, spanning the past several hundreds ...
-
(2001)The latest Mesoproterozoic Burovaya Formation is a 600–1000 m thick stromatolite/mud dominated carbonate unit demarcated by an erosional unconformity into two subformations containing stromatolite reefs of variable size ...
-
(2006)This study focuses on the sequence stratigraphy of the Pyeongan Supergroup (Carboniferous-Permian), central-eastern Korea. The supergroup consists of about 1700-m-thick siliciclastic deposits, disconformably overlying the ...
-
(1997)Comparative K-Ca and Rb-Sr data for extremely radiogenic muscovites (#Ca=2300 to 18,700; 87Sr/86Sr=52 to 991) from two unmetamorphosed Archaean pegmatitic rocks from the Jack Hills in the northwestern part of the Yilgarn ...
-
(2006)Mine tailings may be remediated using metal tolerant microorganisms as they may solve the limiting conditions for healthy development of plants (i.e., low organic mater content and poor physical conditions). The aim of ...
-
(2001)In order to elucidate high-pressure transformations of high-P clinopyroxene (C2/c) at kinetically low temperature where atoms are not thermally activated, the transformation processes of FeGeO3 clinopyroxene (C2/c) have ...
-
(2004)This study explores a chemo-thermo-dynamic subduction zone model that solves for slab dehydration during subduction. We investigate how changes in the incoming plate's hydration and thermal structure may effect the efficiency ...
-
(2006)The Weches Formation of the Claiborne Group (Eocene) in northeast Texas consists of clayey sandstones and mudrocks, both with variable proportions of dark green to brown clay peloids deposited in a marginal to open marine ...
-
(2004)High-resolution transmission electron microscopy (HRTEM) affords a close look at the complex structures and intergrowths of the serpentine minerals. All contain alternating sheets of cations in tetrahedral and octahedral ...
-
(2006)Alpine antigorite serpentinites associated with eclogites were investigated to determine if they can be used as indicators of the tectono-metamorphic conditions during subduction and exhumation processes. The detailed ...
