(2006)This paper addresses Ag-sulfotellurides occurring in volcanic-hosted massive sulfide deposits of the Southern Urals. Cervelleite-like minerals were identified in ores from the Gayskoe, Yaman-Kasy, Severo-Uvaryazhskoe, ...
-
(2006)Ice-dammed lakes were repeatedly formed in intermontane basins in the Russian Altai Mountains throughout the Pleistocene. These cataclysmic outburst floods, caused by icedam failures, were documented as Earth's largest ...
-
(2006)В настоящее время уран является одним из важнейших энергоносителей. Рост энергопроизводства, необходимый для экономического развития России, в ближайшие десятилетия будет обеспечиваться главным образом за счет атомной ...
-
(2006)Columnar stromatolites representing more than a half of species described in Precambrian stromatolite assemblages reveal a regular trend of size variations during the Proterozoic and Early Paleozoic. Their dimensional ...
-
(2006)Water-related features were studied using infrared absorption spectroscopy in fibrous diamonds with micro-inclusions. Both OH-stretching and HOH-bending vibrations were observed. The lack of correlation between the intensities ...
-
(2006)Early Proterozoic granitoids are of a limited occurrence in the Baikal fold area being confined here exclusively to an arcuate belt delineating the outer contour of Baikalides, where rocks of the Early Precambrian basement ...
-
(2006)Structural evolution of the Kamchatka-Aleutian junction area in late Mesozoic and Tertiary was generally controlled by (1) the processes of subduction in Kronotskiy and Proto-Kamchatka subduction zones and (2) collision ...
-
(2006)New investigations considerably extended taxonomic list of microbiotas from cherts of the Kataskin and Revet subformations of the Avzyan Formation in the Yurmata Group, the Middle Riphean stratotype in southern Urals. It ...
-
(2006)This paper addresses one part of an outstanding tectonic problem regarding the nature of the plate boundary between Eurasia and North America in northeastern Russia. In this region, the northwestern corner of the Pacific ...
-
(2006)Конвективно-рециклинговая модель рудогенеза, изначально разработанная для субмаринныхместорождений колчеданного семейства, в дальнейшем оказалась применимой и к другим месторождениям.
-
(2006)Chemical analyses and Raman micro-spectroscopy have identified whitlockite (water- and halogen-free phosphate) in mantle xenoliths from Siberia. Whitlockite has not previously been reported from terrestrial mantle-derived ...
-
(2006)Single-crystal polarized Raman spectra (80 to 4000 cm-1 at 4 ≤ T ≤ 700 K) and powder IR spectra (1500 to 4000 cm-1 at 50 < T < 300 K) were measured for two microporous zeolites natrolite, Na16[Al16Si24 O80]·16H2O, and ...
-
(2006)Changes in morphological diversity and taxonomic composition of late Albian-early Turonian foraminiferal and radiolarian assemblages from the northern Peri-Tethys are considered. Several stages are defined in evolution of ...
-
(2006)The study focuses on the mode of occurrence of Au, Ag and Te in ores of the Gaisk, Safyanovsk, Uzelginsk and other volcanic-hosted massive sulfide (VHMS) deposits in the Russian Urals. Minerals containing these elements ...
-
(2006)The heat capacity of synthetic anhydrous Mg-cordierite (Mg2Al4Si5O18) was measured using adiabatic calorimetry between 6 and 300 K. Mg-cordierite was synthesized from a glass of stoichiometric cordierite composition at ...
-
(2006)A phase of Mesozoic extension associated with the termination of continental collision at the southern margin of the Aldan Shield produced ultrabasic lamproites in a discontinuous belt 500 km long and ~150 km wide. The ...
-
(2006)We have developed a simple, yet accurate theoretical method for calculating the reduced isotope partition function ratio (RIPFR) for hydrogen of water at elevated pressures. This approach requires only accurate equations ...
-
(2006)Nanometer-size P/K-rich silica glass (former melt) inclusions were identified within metamorphic microdiamonds from garnets of ultrahigh-pressure (UHP) gneisses of the Kokchetav and the Erzgebirge massifs by analytical ...
-
(2006)Distribution of belemnites and benthic foraminifers in the Campanian-Maastrichtian boundary layers of the Aktulagai section, one of Upper Cretaceous reference sections in the east of the European paleobiogeographic region ...
-
(2006)The Late Paleozoic Kochbulak and Kairagach deposits are located on the northern slope of the Kurama Ridge, Middle Tien Shan, in the same volcanic structure and the same ore-forming system. Au-Ag-Cu-Bi-Te-Se mineralization ...
