(2021)Many studies have been devoted to the study of oceanic crust, much less on its continental equivalent. It has been known for a long time that the average composition of the continents is approximately granitic, with however ...
-
(2011)The Altai-Sayan Fold Belt epitomises how Phanerozoic island-arc continental crust contributed to the growth of the Palaeo-Eurasian continent. Its formation is dominated by the closure of the Palaeo-Asian Ocean (PAO) when ...
-
(2014)We report on the structure, geochemistry, Re–Os isotopes and relative abundances of highly siderophile elements (HSEs) of the Paleozoic peridotite–basalt occurrences in the Eastern Pontide belt of northeastern Turkey. These ...
-
(2010)U/Pb dating, REE geochemistry and Lu/Hf isotopic studies utilizing LA-ICPMS on detrital zircon suites from Neoproterozoic siliciclastic rocks fromthe northeast periphery of the East European Craton (sandstones of Djejim ...
-
(2021)Granitoid magmatism is widespread in the Mongolian Altai, and it provides critical information to understand the crustal formation, evolution, and growth. This study reports newly investigated petrography, whole–rock ...
-
(2013)It is well documented that the Khondalite Belt of the North China Craton formed by the collision of the Yinshan and Ordos Blocks during ca. 1.95 Ga, but the onset of the post-collisional exhumation stage has not been well ...
-
(2014)Gravity phenomena related to the Earth movements in the Solar System and through the Galaxy are reviewed. Such movements are manifested by geological processes on the Earth and correlate with geophysical fields of the ...
-
(2005)Основными геодинамическими режимами на рудном этапе формирования месторождений олова в Северо-Западном секторе Тихоокеанского рудного пояса являются раннемеловая коллизия и меловая?палеогеновая окраинно-континентальная ...
-
(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 ...
