(2002)The 370–380 Ma Khibina and Vuoriyarvi complexes on the Kola Peninsula, Russia, which form part of the Palaeozoic Kola Alkaline Province, contain REE-rich carbonatites with burbankite (Na,Ca)3(Sr,Ca,REE,Ba)3(CO3)5 or ...
-
(1999)Burbankite, ideally (Na,Ca) 3(Sr,REE,Ba)3(CO3)5, is a rare REE carbonate mineral that until now had been encountered only at a few localities including highly alkaline silicate rocks, carbonatites, and lacustrine sediments. ...
-
(2004)The GALO system is applied to the numerical reconstruction of burial and thermal histories of the West Bashkirian lithosphere from the Riphean to the present. An analysis of the variation in tectonic subsidence of the basin ...
-
(2001)The morphology of the gravity field and the distribution of Pliocene ignimbrites were analyzed to locate Late Neogene calderas which had been covered by younger volcanic formations.
-
(2002)Burnsite, ideally KCdCu7O2(SeO3)(2)Cl-9, occurs in a fumarole in the North Breach of the great fissure Tolbachik volcano eruption (1975-1976), Kamchatka Peninsula, Russia. It occurs as dark red, anhedral, equidimensional ...
-
(2000)Рассматриваются закономерности распределения взвеси и ряда химических элементов в эстуариях Оби и Енисея. Приведены данные по вещественному гранулометрическому и химическому составу взвесей (Сорг, Si, Al, Са, Fe, Mn, Ti, ...
-
(2019)Получена С- и Sr-изотопная характеристика и определен Pb–Pb возраст карбонатных пород вороговской серии в ее типовом разрезе по р. Вороговка на северо-западе Енисейского кряжа. Отложения серии в составе северореченской, ...
-
(1994)Combined laser extraction and manometric-quadrupole-mass spectroscopic measurements permit the simultaneous analysis of CO2, He and Ar in selected fluid inclusion generations trapped in a dunite nodule from Reunion Island. ...
-
(2001)Two secular variation curves of C-isotope composition in the Late Riphean carbonates are discussed. The curve approximating data on the Upper Riphean deposits of Spitsbergen, Greenland, northwestern Canada, and southwestern ...
-
(1989)Geothermal oil, found in rift zones, is an indicator of vigorous geochemical, geological and biological alteration of matter. Appearances of petroleum hydrocarbons have been detected in areas of hot (315°C) brines springs ...
-
(2001)The C25 highly branched alkenes which have been widely reported in coastal and deep sea marine sediments and sedimenting particles have to date only been detected in benthic diatoms. Logically, a planktonic organism would ...
-
(1995)A series of novel C32-C36 polymethylhentriacontenes has been identified in near-surface sediments of the Black Sea. Hydrogenation of these components indicated that they possess the 5,8,14,24,27-pentamethyl-, 8,14,24,27- ...
-
(2004)X-ray absorption spectroscopy at Ca and Na K-edges and Molecular Dynamics (MD) simulations are used to investigate the Ca and Na environment in soda lime aluminosilicate glasses. Both X-ray Absorption Near Edge Structure ...
-
(2004)Based on their mineralogy and petrography, ~200 refractory inclusions studied in the unique carbonaceous chondrite, Acfer 094, can be divided into corundum-rich (0.5%), hibonite-rich (1.1%), grossite-rich (8.5%), compact ...
-
(2003)The petrography and mineral chemistry of 110 Ca-, Al-rich inclusions (CAIs) and 9 Ca- and/or Al-rich amoeboid olivine aggregates (AOAs) from the Ningqiang carbonaceous chondrite are reported. These CAIs are referred to as ...
-
(Минералогический музей им. А.Е. Ферсмана РАН (Москва), 2007)Изучен стронцианит из метакимберлитов трубки Зарница. По минеральным ассоциациям и изотопному составу углерода и кислорода Са-содержащий стронцианит и ассоциирующие минералы имеют метаморфогенно-гидротермальный генезис и ...
-
(2003)Cadmium sorption on the hematite-electrolyte solution interface was studied in a wide range of pH and Cd2+ concentration by means of potentiometric titration and measurement of cadmium content in the solution. Computer ...
-
(2002)A dated core from the profoundal zone in a pristine oligotrophic acidic lake was analyzed for Cd as well as for Al, Ca, Fe, Mg, Mn, Pb, Ti and total carbon and nitrogen. Overlying water and porewater samples were also ...
