-
(2022)Geoscientists use observations and descriptions of the rock record to study the origins and history of our planet, which has resulted in a vast volume of scientific literature. Recent progress in natural language processing ...
-
(2019)A variety of detailed data about geological topics and geoscience knowledge are buried in the geoscience literature and rarely used. Named entity recognition (NER) provides both opportunities and challenges to leverage ...
-
(2003)Temporal irregularity of the output of volcanic material is studied for the sequence of large (V ≥ 0.5 km3, N = 29) explosive eruptions on Kamchatka during the last 10,000 years. Informally, volcanic productivity looks ...
-
(2016)Terrestrial magmatism is dominated by basaltic compositions. This definition encompasses mid-ocean ridge basalts (MORB), which account for more than eighty percent of Earth’s volcanic products and which are formed at ...
-
(2006)Osmium, Ru, Ir, Pt, Pd and Re abundances and 187Os/188Os data on peridotites were determined using improved analytical techniques in order to precisely constrain the highly siderophile element (HSE) composition of fertile ...
-
(2005)New analyses of highly siderophile elements (HSE; Re, Os, Ir, Ru, Pt, and Pd) obtained by Carius tube digestion isotope dilution inductively coupled plasma mass-spectrometry (ID-ICPMS) technique are reported for 187Os-enriched ...
-
(1999)The combination of geological, tephrochronological and geochemical studies is used to reconstruct the Holocene eruptive history of Ksudach volcanic massif, South Kamchatka and to trace the evolution of its magma. Ksudach ...
-
(1997)Detailed tephrochronological studies in Kamchatka Peninsula, Russia, permitted documentation of 24 Holocene key-marker tephra layers related to the largest explosive eruptions from 11 volcanic centers. Each layer was traced ...
-
(2009)The influence of water concentration on the crystallization temperature of amphibole in a melt was analyzed theoretically using the model of an ideal melt. A general-type equation has been derived that can explain the ...
-
(2013)The interplay of geodynamic and sedimentation processes in the Central Asian orogen and the Siberian craton is discussed in several aspects: (i) general tectonics of the Central Asian orogen, (ii) correlation of deposition ...
-
(1995)We studied the tectonic setting, morphology, geologic structure, history of eruptive activity and evolution of the composition of the erupted material of Kizimen volcano, Kamchatka, from the moment of its origination 11–12 ...
-
(2005)Edifices of stratocones and domes are oftensituated eccentrically above shallow silicic magmareservoirs. Evacuation of such reservoirs forms collapsecalderas commonly surrounded by remnants of one orseveral volcanic ...
-
(2014)Ultra-high-temperature (UHT) granulite-facies rocks offer important constraints on crustal evolution processes and tectonic history of orogens. UHT granulites are generally rare in Phanerozoic orogens. In this study, we ...
-
(2015)The Jiamusi massif is a major tectonic unit in the eastern part of NE China and composed chiefly of the Early Paleozoic (about 500 Ma) metamorphosed crystalline basement containing Precambrian, even Archean crust and three ...
