(2008)Two powerful eruptions of Quizapu vent on Cerro Azul Volcano, Chile are used as examples to discussthe problem of effusive eruptions of magmas having high preeruptive volatile concentrations. A physicochemicalmechanism is ...
-
(2014)The 2012-2013 Tolbachik Fissure eruption started from lava gushing and effusion in the Menyailov vent on November 27 th , 2012; after three days the activity of this vent ceased and the eruption continued from the Naboko ...
-
(2006)Separation of a metal-rich core strongly depleted the silicate portion of the Earth in highly siderophile elements (HSE), including Pt, Re, and Os. To address the issues of how early differentiation, partial melting, and ...
-
(2004)Precise Pt–Re–Os isotopic and highly siderophile element (HSE) data are reported for 10 drill core samples collected across a 2.7 m thick, differentiated komatiite lava flow at Pyke Hill in Ontario, Canada. The Pt–Re–Os ...
-
(1993)On the basis of the writer's data of the migration of great 18-20th century earthquakes and their repeat times he offers a forecast of the times of large earthquakes that are likely to occur in the northern Kurils and ...
-
(2010)Xenolithic peridotites having a similar range of major element compositions from two nearby localities in the Trans-North China Orogen, North China Craton, provide a rare opportunity to explore effects resulting from both ...
-
(1990)A matematical model is given of the formation of phreatic explosions in lava flows coming into contact with ice formations. Quantitative characteristics are derived for the various stages in the development of the explosion; ...
-
Pt–Re–Os and Sm–Nd isotope and HSE and REE systematics of the 2.7 Ga Belingwe and Abitibi komatiites (2009)High-precision Pt–Re–Os and Sm–Nd isotope and highly siderophile element (HSE) and rare earth element (REE) abundance data are reported for two 2.7 b.y. old komatiite lava flows, Tony's flow (TN) from the Belingwe greenstone ...
-
(2002)The 8–10 May 1997 eruption of Bezymiannyvolcano began with extrusion of a crystallized plug fromthe vent in the upper part of the dome. Progressive gravi-tational collapses of the plug caused decompression ...
-
(1993)We discuss results of 14C dates obtained from areas of young volcanoes in Kamchatka. We apply these dates to reconstructing regional volcanic activity during the Holocene.
-
(2007)Radiocarbon dating is widely used when studying recent volcanic activity in the Kamchatka Peninsula due to the abundance of organic matter that is associated with the volcanic deposits. Here, we present the results of 14C ...
-
(2016)Приведены первые данные по Rb-Sr изотопной систематике магматических пород дайкового комплекса и гранитов Дузуньинского массива, развитых в пределах Ольчан-Нерской металлогенической зоны (Восточная Якутия): андезито-базальты ...
