(2007)New isotopic studies of 142Nd, the daughter product of the short-lived and now extinct isotope 146Sm, have revealed that the accessible part of the silicate Earth (e.g., upper mantle and crust) is more radiogenic in ...
-
(2014)The pace of revolution in analytical chemistry in the field of Geosciences has been dramatic over the recent decades and includes fundamental developments that have become common place in many related and unrelated ...
-
(2006)Проведен анализ имеющихся в литературе мировых данных о минеральном составе, стадийности минералообразования, РТХ-условиях формирования, субстрате исходных пород, источнике флюида при формировании родингитов, несущих золотое ...
-
(2016)В Киалимской и Малоиремельской золотых россыпях Миасской россыпной зоны на Южном Урале найдено 24 минерала элементов платиновой группы (ЭПГ). Родарсенит, боуит, купрородсит и ксингцхонгит(?) на Урале обнаружены впервые. В ...
-
(2019)Обсуждаются результаты определения U-Pb изотопного возраста уранового оруденения Туюканского рудного узла в Тонодском районе методом изотопного разбавленя и термоионной масс-спектрометрии (ТИМС) по настурану. Установлено, ...
-
(2020)Анализируются геологические и возрастные особенности формирования уранового оруденения Патомского нагорья, развитого на Тонодском и Нечерском поднятиях. Обосновывается вывод о принадлежности уранового оруденения Патомского ...
-
(2006)Несмотря на широкое развитие родингитов в ультраосновных породах во многих регионах мира, данные о газовом составе сформировавших их флюидов практически отсутствуют. Является признанным, что минеральные парагенезисы ...
-
(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 ...
-
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 ...
-
(2010)n this study, we present Lu–Hf isotope systematics and Lu and Hf abundances for komatiites from the lowermost part of the 2.8 Ga Kostomuksha greenstone belt in the Baltic Shield and compare these, as well as available Sm–Nd ...
-
(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 ...
-
(2005)Some hotspot volcanism is likely the surface manifestation of hot upwelling mantle plumes that rise from the core–mantle boundary (CMB) or from compositional boundaries within the mantle. Plumes that rise from the CMB may ...
-
(2016)New Os isotope and highly siderophile element (HSE) abundance data, in combination with lithophile trace element and Sm–Nd, Lu–Hf, and Hf–W isotope data, are reported for komatiitic basalts from the Vetreny Belt and tonalites ...
-
(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 ...
-
(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 ...
-
(2023)Mineral image recognition is a challenging computer vision problem. Without external tools, even a human expert cannot distinguish some mineral species accurately. Previous research was mainly focused on processed mineral ...
-
(2020)The description of rocks is one of the most time-consuming tasks in the everyday work of a geologist, especially when very accurate description is required. We here present a method that reduces the time needed ...
-
(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 ...
-
(2023)Large language models (LLMs) have achieved great success in general domains of natural language processing. In this paper, we bring LLMs to the realm of geoscience with the objective of advancing research and applications ...
