(2001)Thick, unmetamorphosed successions of siliciclastic and carbonate rocks in eastern and western Siberia preserve a record of Middle Riphean to Early Upper Riphean sedimentary environments and geochemistry. Consistent with ...
-
(2001)Geology and gold mineralisation of the Sutara and Priamurye auriferous districts in the Jewish Autonomous Region are briefly reviewed in the paper. Placers have being mined for more than a hundred years in these districts ...
-
(2003)The 3 He/ 4 He = R ratio was studied in underground fluids from 104 sites from the Baikal Rift Zone (BRZ) and adjacent areas in Russia and Mongolia. The R -values vary in a wide range from R=0.01R A (crustal radiogenic He) ...
-
(1999)The paper gives the definition of the North-Asian craton as a geological structure. The evolution of conception and views of its structure and boundaries is considered, and a brief overview of its geologic history in terms ...
-
(1989)That pre-Paleozoic volcanic rocks occur widely in the Polar Urals has been known for a long time. High-magnesium andesites and boninites of the Polar Urals resemble in their geological position, as well as their petrography ...
-
(2005)Дискуссия о возрасте нефелиновых сиенитов Бердяушского массива расположенного на западном склоне Южного Урала и прорывающего стратотипические рифейские образования Башкирского антиклинория имеет длительную историю. Новые ...
-
(1999)New sites of mineralized microfossils, seven in cherts and one in phosphorite of the Upper Riphean Valyukhta Formation-of the Baikal-Patom Highland, are discovered at the Alekan River (the Malaya Chuya River basin). The ...
-
(1983)Linear extensional rift and rift-like structures have been generated many times during various periods of the Earth's history since early times. These structures have varied with time, however, in scale, morphology, ...
-
(1987)The melanocratic rock association considered represents the basement of the outer part of the Northwest Pacific paleo-oceanic fringe. It is confined to the zone where oceanic crustal complexes taper among crystalline rock ...
-
(1999)The specific features of the Central-Asian orogenic belt (CAOB) and marginal structures of the North-Asian craton are considered on the basis of analysis of lithospheric-plate tectonics and terrain analysis. The general ...
-
(2004)Microphytological remains from Riphean deposits of the Mezen syneclise (Leshukon depression) have been Eudied in 115 core samples characterizing in detail a sedimentary section penetrated by deep borehole Srednyaya Nyafta ...
-
(2001)Silicided microfossils from the Middle Riphean Svetlyi Formation of the Riphean hypostratotype in the Uchur-Maya region of southeastern Siberia are described for the first time. Cherts are discovered to enclose only simple ...
-
(2002)Organic-walled microfossils from the Riphean hypostratotype of Siberia (the Uchur-Maya region), which represent the Early Riphean Uchur (Omakhta) and Late Riphean Ui (Kandyk and Ust'-Kirba) microbiotas, are considered. The ...
-
(2003)New materials studied (over 200 samples) and published data critically analyzed are used to specify composition of organic-walled microfossils and to elucidate their vertical and lateral distribution in the Upper Riphean ...
-
(1994)Silicified shallow-water marine carbonate deposits of the Proterozoic Debengda Formation (the Olenek Uplift, northeastern Siberia) contain well preserved microfossils. One or two distinct assemblages consists only of ...
-
(2000)The paper considers the structure, lithology, and facies characteristics of the Yurmatin and Serafimovka groups of the Bashkir meganticlinorium and Volga–Urals region. The analyzed distribution schemes of facies associations ...
-
(2005)Приведена характеристика своеобразных верхнепротерозойских образований - извилистых трещинок в обогащенных органическим веществом карбонатных породах. Трещинки, выполненные преимущественно кальцитом, образуют систему светлых ...
-
(2004)New paleontological findings, analysis of section structure, and literature data on the Neoproterozoic stratigraphy of the Altai-Sayan Folded Area, ASFA, provide support to the recognition of three heterochronous polyfacies ...
-
(2004)Silicified microfossils found in the Satka Formation of the Burzyan Group (Lower Riphean stratotype of the southern Urals) are described. The research carried out augments the database on taxonomic composition of relevant ...
