(2005)The fractionation of lithium isotopes among quartz, muscovite, and a chloride-bearing aqueous fluid has been investigated experimentally at 400°–500°C and 50–100 MPa. Experiments were performed for 15–60 days in cold seal ...
-
(2004)The Li isotopic composition of the upper continental crust is estimated from the analyses of well-characterized shales, loess, granites and upper crustal composites (51 samples in total) from North America, China, Europe, ...

LITHIUM ISOTOPIC SYSTEMATICS OF THE MANTLE-DERIVED ULTRAMAFIC XENOLITHS: IMPLICATIONS FOR EM1 ORIGIN (2004)Isotopic signatures of mantle-derived xenoliths have provided much information on the evolution of their mantle source regions. A recently developed multiple-collector inductively coupled plasma mass spectrometry method ...

(Днепропетровский национальный университет им. Олеся Гончара, 2019)This paper addresses issues related to the complexity of the geological structure of the Burdigallian-Langhian sediments of the Stebnyk suite, which were formed in the Carpathian segment of Paratethys. The correlation of ...
-
(2004)The composition of Aptian–Albian rocks in the western Ciscaucasus is considered. Their lithofacies features and formation conditions are established. The data obtained can be used to determine the mineralogical potential ...
-
(PANGAEA, 1999-09-17)In order to evaluate the sensitivity of aquatic and terrestrial ecosystems to climatic changes, lithological (sediment structure and color, grain size, physical properties) and biochemical (TOC, TOC/TN, d13C of TOC and ...
-
(Общество с ограниченной ответственностью «Георесурсы», 2018)A conodont sequence from the Przhidolian stage of the Upper Silurian and almost the entire Lokhkovian stage of the Lower Devonian has been established in the sections of the Upper Silurian-Lower Devonian on the southwestern ...
-
(2004)Implications of ion exchange processes for the formation of lithological and hydrogeochemical systems under various thermobaric conditions of the subsurface hydrosphere are discussed on the basis of on-location, experimental, ...
-
(2004)Based on traditional petrochemical and nontraditional mineralogical methods (accessory zircon generation analysis), specific features of the primary composition of strongly metamorphosed rocks from some Early Precambrian ...
-
(2004)Upper Cambrian-Lower Ordovician volcanic-siliceous-terrigenous strata of the Zasur'ya Group belonging to the Gorny Altai segment of the Paleo-Asian Ocean are considered in this paper. The Gorny Altai segment developed over ...

(1997)Using ferromagnetic resonance (FMR) and instrumental neutron activation analysis (INAA), we have determined the maturity (surface exposure) parameter Is/FeO and concentrations of twenty-five chemical elements on samples ...
-
(2001)The complex study of uranium ores and their host rocks of the Malinovskoe deposit revealed their specific mineralogical and geochemical peculiarities, which it differentiate them from all known ancient and recent exogenic ...
