Momentum-wave nature of geological mediumMoscow University Geology Bulletin - Tập 63 - Trang 368-371 - 2008
A. V. Vikulin, T. Y. Tveritinova
This paper is a further development of A.V. Pejve and M.A. Sadovskii’s concepts of the block structure of geological and geophysical media. Pejve’s geological hypothesis of “the independent motion power” of a block, “contained in it” is supported by geological-geophysical evidence and thus acquires a new physical content. Using seismological data within the framework of a radically new “internal m...... hiện toàn bộ
The 35th Session of the International Geological Congress, Cape Town, 2016Moscow University Geology Bulletin - Tập 72 - Trang 231-234 - 2017
V. I. Starostin, A. L. Perchuk, A. V. Bobrov
The results of the 35th Session of the International Geological Congress held in 2016 in Cape Town (South Africa) are discussed in this paper. The major scientific problems discussed at the most popular sections are considered. Among them are the early stages in the evolution of the Earth, studies of mineral resources worldwide, and the problems of the deep structure of the Earth, as well as moder...... hiện toàn bộ
Upper Cretaceous sediments in the Russian Plate: Sequence stratigraphy and Milankovitch cyclesMoscow University Geology Bulletin - Tập 62 - Trang 306-317 - 2007
R. R. Gabdullin
The paper discusses integrated sequence-cyclostratigraphic analysis of Upper Cretaceous sediments based on 9 sections in the Russian Plate (the Voronezh Anteclise and the Ulyanovsk-Saratov Basin). Tracts (transgressive and highstand) were for the first time recognized in sections of this region and compared with member-by-member subdivision, bed rhythmites, and Milankovitch cycles indicating their...... hiện toàn bộ
The Cr6+ impurity in supergene oxosalts in chromate mineralization occurrences of the UralsMoscow University Geology Bulletin - - 2017
D. A. Khanin, I. V. Pekov, A. V. Pakunova, I. A. Ekimenkova, V. O. Yapaskurt
Based on the results of more than 600 electron microprobe analyses of 25 minerals the distribution pattern of the Cr6+ impurity in vanadates, phosphates, and arsenates collected in oxidation zones of six ore deposits of the Urals was studied. Among them are Pb minerals of the brackebuschite, apatite, adelite, and tsumcorite groups and alunite supergroup, as well as carminite, cornwallite, and bayi...... hiện toàn bộ
Geological and geochemical features of the auriferous Butarny depositMoscow University Geology Bulletin - Tập 64 - Trang 383-385 - 2009
N. V. Cherepanova
The Butarny deposit is characterized by the development of mineralization of gold-quartz and gold-rare metal mineral associations related to Late Cretaceous granitoid magmatism and metasomatism imposed during the Late Jurassic tectonomagmatic epoch. Ores on the Butarnoe site were formed during the vein quartz-sulphide stage and partially oxidized in a zone of hypergenesis. The gold found there is ...... hiện toàn bộ
Geological structure of the Ubinka River valley (Northwestern Caucasus)Moscow University Geology Bulletin - Tập 66 - Trang 331-340 - 2011
A. V. Marinin, L. Ph. Kopaevich, S. I. Stupin
A thick olistostrome strata of late Paleocene-early Eocene age is outlined in the northern flank of the Northwestern Caucasus folded structure in the Ubinka river valley, which shows the significant role of earlier Cenozoic tectonic movements in forming the alpine structure of the region. The largest part of the strata is composed of dark weakly calcareous clays, which were earlier recognized as L...... hiện toàn bộ
