COMAGMATIC GRANOPHYRE AND DACITE FROM KARYMSKY VOLCANIC CENTER, KAMCHATKA: EXPERIMENTAL CONSTRAINTS FOR MAGMA STORAGE CONDITIONS

Izbekov P.; Gardner J.E.; Eichelberger J.C. (2004)

Despite a ∼30 000 years difference in age, two caldera-forming eruptions at Karymsky volcanic center, Kamchatka – Karymsky (7900 yr BP) and Academy Nauk (ca. 40 000 yr BP) – produced two-pyroxene dacites with the same ...

COMBINATION OF DEPENDENT REALIZATIONS WITHIN THE GRADUAL DEFORMATION METHOD

Hu L.Y. (2002)

Gradual deformation is a parameterization method that reduces considerably the unknown parameter space of stochastic models. This method can be used in an iterative optimization procedure for constraining stochastic ...

COMBINED ANALYSIS OF SKS SPLITTING AND REGIONAL P TRAVELTIMES IN SIBERIA

Oreshin S.; Vinnik L.; Makeyeva L.; Kosarev G.; Kind R.; Wentzel F. (2002)

Azimuthal anisotropy in the upper mantle of many continental regions is documented by S-wave splitting measurements with SKS techniques. Here we present observations of splitting of the SKS seismic phase at seismograph ...

COMBINED DETECTION OF ELECTROMAGNETIC AND ACOUSTIC EMISSIONS ASSOCIATED WITH ROCK FAILURE

Poturayev V.N.; Bulat A.F.; Khokholev V.K. (1989)

We describe investigations of acoustic and electromagnetic emissions in rocks under pressure. Their combined use provides quantitative measures of the stress state of the rock body and makes it possible to study the ...

COMBINED EFFECTS OF TECTONICS AND GLACIAL ISOSTATIC ADJUSTMENT ON INTRAPLATE DEFORMATION IN CENTRAL AND NORTHERN EUROPE: APPLICATIONS TO GEODETIC BASELINE ANALYSES

Marotta A.M.; Sabadini R.; Mitrovica J.X.; Milne G. (2004)

We use a suite of spherical, thin sheet, finite element model calculations to investigate the pattern of horizontal tectonic deformation within Europe. The calculations incorporate the effects of Africa-Eurasia convergence, ...

COMBINED GEOTHERMAL-GEOPHYSICAL MODELS OF THE EARTH'S CRUST AND UPPER MANTLE FOR THE EUROPEAN CONTINENT

Gordienko V.V.; Pavlenkova N.I. (1985)

An attempt is made to obtain a combined geophysical model along two regional profiles: Black Sea— White Sea and Russian Platform—French Central Massif. The process of the model construction had the following stages: 1. The ...

COMBINED IN SITU X-RAY DIFFRACTION AND RAMAN SPECTROSCOPY ON MAJORITIC GARNET INCLUSIONS IN DIAMONDS

Kunz M.; Gillet P.; Fiquet G.; Sautter V.; Graafsma H.; Conrad P.; Harris J. (2002)

Mineral inclusions in Sao Luiz diamonds have been characterized using angle dispersive X-ray diffraction and Raman spectroscopy. We identified two different garnet phases coexisting with an omphacitic pyroxene. They represent ...

COMBINED INTERPRETATION OF RADAR, HYDRAULIC, AND TRACER DATA FROM A FRACTURED-ROCK AQUIFER NEAR MIRROR LAKE, NEW HAMPSHIRE, USA

Day-Lewis F.D.; Lane J.W.; Gorelick S.M. (2006)

An integrated interpretation of field experimental cross-hole radar, tracer, and hydraulic data demonstrates the value of combining time-lapse geophysical monitoring with conventional hydrologic measurements for improved ...
