On the Cycles of Tectogenesis in the Urals

This paper reinterprets the geotectonic history of the Ural geotectonic province, including the Urals, Mugodzhar, Novaya Zemlya, and partly Timan, through a synthesis of stratigraphic, structural, magmatic, and metamorphic evidence. It argues that the region records multiple cycles of tectogenesis, …

Genesis of Ferberite Ore Deposits in the Upper Racha District (Transcaucasia)

This paper examines the origin of ferberite and associated ore deposits in the Upper Racha district of Western Georgia, where tungsten, molybdenum, mercury, antimony, and related mineralization occur in a structurally complex belt of Liassic argillaceous shales near a major overthrust zone. Drawing …

New Data on the Karst of Northeastern Salair

This paper presents new observations on karst development in northeastern Salair, drawing on hydrogeological surveying and engineering-geological investigations conducted in connection with regional prospecting and the projected Altaiskaya to Kuzbass railway. It describes the geological setting of C…

On the "Lower Silurian" of the Western Sayan

This paper reexamines the thick metamorphosed greenstone succession of the Western Sayan that earlier geological maps and studies had treated broadly as Lower Silurian. On the basis of field observations from geological surveys, lithological distinctions, metamorphic grade, structural relations, int…

Several Remarks on Iron Ores (Siderites) among Jurassic Coal-Bearing Deposits of the Southeastern Margin of the Chulym-Yenisei Coal-Bearing Basin

This paper reviews siderite iron ore occurrences within Jurassic coal-bearing deposits on the southeastern margin of the Chulym-Yenisei basin, describing their lithology, stratigraphic position, chemistry, and spatial distribution. Drawing on field observations, earlier geological reports, chemical …

Lower Devonian Spiriferidae of the Northern Altai

This paper describes Lower Devonian spiriferid brachiopods from three fossiliferous localities in the northern Altai, with the aim of improving stratigraphic interpretation of poorly known Siberian Lower Devonian faunas. On the basis of comparative morphological study of internal molds, impressions,…

Granite Intrusions of the Southern Yenisei Ridge

This paper examines the acidic granite intrusions of the Southern Yenisei Ridge and their role in shaping the region’s Precambrian geology, metamorphism, and mineralization. Drawing on three years of field investigation and petrographic study, it outlines a stratigraphic and tectono-magmatic scheme …

Studies on the Methodology of Geological Research

This paper develops a methodological approach for historical analysis of tectonic structures, arguing that geological structures should be reconstructed through successive phases of tectogenesis rather than treated only as cumulative results of folding. It proposes a practical technique for restorin…

Materials on the Tectonics of Intrusions

This paper examines the tectonics of intrusive bodies through an exposition and critique of Hans Cloos’s theory of granite and intrusive tectonics, combined with the author’s observations from Siberia, the Kola Peninsula, and the Caucasus. It analyzes prototectonic structures such as schlieren, line…

Iron Ore Deposits of the Khakass-Minusinsk Region

This paper surveys the iron-ore deposits of the Khakass-Minusinsk region on the basis of geological prospecting, magnetometric surveys, drilling, and exploratory work conducted mainly in the early Soviet planning period. It organizes the deposits by stratigraphic and genetic formation, discussing gr…

List of Scientific Works of Academician M. A. Usov

This bibliographic notice compiles the scientific works of Academician M. A. Usov from 1911 through 1939, with an additional list of works in press. The entries document Usov’s contributions to petrography, tectonics, stratigraphy, ore deposits, coal geology, geomorphology, and geological education,…

The Life and Work of Academician M. A. Usov (1883–1939)

Advances in Understanding the Structure of Silicate Glasses

The principal characteristics of the true solid state of matter are invariability of shape and crystalline structure. The most diverse glasses occupy, in this respect, a not entirely definite position. In their external features they very strongly resemble true solids, but at the same time they poss…
