BASALTIC MAGMATISM AND THE GEODYNAMICS OF THE EAST AFRICAN RIFT SYSTEM

Rogers N.W. (2006)

The major and trace element and radiogenic isotope compositions of basalts from throughout the East African rift system are reviewed in the context of constraints from previous geophysical studies. The data indicate the ...

BASALTIC THERMALS AND SUBPLINIAN PLUMES: CONSTRAINTS FROM ACOUSTIC MEASUREMENTS AT SHISHALDIN VOLCANO, ALASKA

Vergniolle S.; Caplan-Auerbach J. (2006)

The 1999 basaltic eruption of Shishaldin volcano (Alaska, USA) included both Strombolian and Subplinian activity, as well as a "pre-Subplinian" phase interpreted as the local coalescence within a long foam in the conduit. ...

BASALTIC VOLCANISM AND MASS EXTINCTION AT THE PERMO-TRIASSIC BOUNDARY: ENVIRONMENTAL IMPACT AND MODELING OF THE GLOBAL CARBON CYCLE

Grard A.; François L.M.; Dessert C.; Dupré B.; Goddéris Y. (2005)

The Siberian Traps represent one of the most voluminous continental flood basalt provinces on Earth. The mass extinction at the end of the Permian was the most severe in the history of life. In the present paper, these two ...

BASALTS FROM THE FRANZ JOSEF LAND ARCHIPELAGO: NEW GEOCHEMICAL DATA

Chernysheva E.A.; Kharin G.S.; Stolbov N.M. (2003)

Mesozoic intraplate continental basaltic volcanism at the Franz Josef Land (FJL) archipelago is related to the activity of the Iceland plume [1, 2]. The volcanic activity was less significant but genetically close to the ...

BASALTS OF THE ERDAGOU FORMATION AND ITS GEODYNAMIC SETTING IN THE TAUKHA TERRANE, SOUTHERN SIKHOTE-ALIN, PRIMORYE

Simanenko V.P.; Golozoubov V.V.; Kemkin I.V. (2001)

This paper discusses the petrography, petrochemistry and geochemistry of basalts of the Erdagou volcanic-cherty Formation in the Taukha terrane, Southern Sikhote-Alin. The mid-Jurassic (Callovian) age of the basalts is ...

BASANITES OF MT. KHUKHCH: FIRST MINERALOGICAL-GEOCHEMICAL DATA ON THE NEOGENE K-NA ALKALINE MAGMATISM IN WESTERN KAMCHATKA

Perepelov A.B.; Puzankov M.Yu.; Filosofova T.M.; Ivanov A.V. (2006)

Geotectonic reconstruction of the Cenozoic structure of western Kamchatka suggests the wide development of rifting in Paleogene and Neogene in this region[1]. However, magmatic complexes typical of this geodynamic setting ...

BASE CATION CYCLING IN A PRISTINE WATERSHED OF THE CANADIAN BOREAL FOREST

Duchesne L.; Houle D. (2006)

Base cation cycling was investigated on the Canadian Shield in a pristine catchment of the boreal forest. An input–output budget (atmospheric deposition – stream exports) for the whole watershed indicated that nitrogen (N) ...

BASE METAL - PLATINUM-GROUP ELEMENT SULFIDES FROM THE URALS AND THE EASTERN ALPS: CHARACTERIZATION AND SIGNIFICANCE FOR MINERAL SYSTEMATICS

Melcher F. (2000)

A mineralogical classification of sulfides containing base metals (BM) and platinum group elements (PGE) is proposed based on BM-PGE ratios. Group A comprises BM sulfides carrying PGE as trace or minor elements (e.g., ...

BASELINE STUDIES OF THE CLAY MINERALS SOCIETY SOURCE CLAYS: INFRARED METHODS

Madejová J.; Komadel P. (2001)

Infrared (IR) spectroscopy has a long and successful history as an analytical technique and is used extensively (McKelvy et al., 1996; Stuart, 1996). It is mainly a complementary method to X-ray diffraction (XRD) and other ...

BASELINE STUDIES OF THE CLAY MINERALS SOCIETY SOURCE CLAYS: SPECIFIC SURFACE AREA BY THE BRUNAUER EMMETT TELLER (BET) METHOD

Dogan A.U.; Dogan M.; Onal M.; Sarikaya Yu.; Aburub A.; Wurster D.E. (2006)

Specific surface area measurements of The Clay Minerals Society source clays were made by the Brunauer, Emmett and Teller (BET) method of adsorption of nitrogen gas. Two replicate measurements of specific surface area were ...

BASEMENT UPLIFT OF THE MONGOL-SIBERIAN REJUVENATED OROGEN

Ufimtsev G.F.; Shchetnikov A.A. (2001)

The Mongol-Siberian belt of rejuvenated mountains is an ordered system of large domes, zones of linear warping, and the Baikal rift zone on the broad basement doming. Its morphology is paragenetically related to the shape ...
