Biography Alexander Wiechert Voldemarovich
Candidate of Geological and Mineralogical Sciences (1956), Doctor of Geological and Mineralogical Sciences (1975). Senior Researcher (1963). Head of the Laboratory of Mathematical Methods in Geology, Geological Faculty (1967-1971). Senior Research Fellow Department of Dynamic Geology of the geological department.
Scientific Secretary of specialized councils Geotectonics and Regional Geology, Moscow State University (1970-1990).
Hagrazhden medal "In memory of 800 anniversary of Moscow". For creating the model of deep structure in conjunction with staff well is under auspices of the received an award VDHH.
Research Interests: tectonics, Tectonophysics, statistical methods in geology, geological survey. Conducted tectonic studies Verkhoyan'e to assess the prospects for oil and tin. As a result of works published several articles and 4 books, most of them are "The sedimentary formations of the West Verkhoyanskii anticlinorium and adjacent territories" (1962). Defended the idea of a long folding in Verkhoyan'e, which began during the Permian depositional. The example of South-East Caucasus, and many other complexly natural and experimental structures by numerical methods of analysis showed the existence in nature of folding different morphological types: salt dome, . scaly, . intermediate, . full, . metamorphic,
. Established their dependence on the viscosity, the power of layered strata, and other parameters. As the leading mechanism of folding saw gravitational convection (diapirism, whipping.). Experimentally demonstrated the influence of carrier roughness (foundation) on the process of convection in a two-layer thickness inversion density. Ha clays, can increase its volume when swelling has led evidence of similarity of folding dilated with the convective. The results of years of work together with other members of the Laboratory of Tectonophysics jointly led in the monograph "Methods of modeling in structural geology" (1988), . main idea of which boiled down to, . that folding is mainly the result of the bulk gravity, . derived from the equilibrium under the influence of deep processes,
. Conducted field research in the Talas Range, Kola Peninsula, in Transbaikalia and in the Urals. Developed a statistical method for determining the magnitude of deformation of grains of arbitrary shape and with his assistance reconstructed strain field Riphean strata of Talas Ridge, . one of the deposits of Transbaikalia and the Paleozoic sediments of the western slope of the Northern Urals,
. Dal forecast the deep structure of the vein deposit (Transbaikalia) and features of the folding mechanism of the formation of convective (Northern Urals). For a variety of geological maps folded regions of the globe gathered and analyzed the orientation of mineral linearity and small joints of folds separately and together on different sets of species: fold-breaking, and cover-intrusive. Found, . that the linearity of the mineral as an indicator of the direction of flow of matter in the folding and razryvoobrazovanii and formation of intrusions tends to orient in the direction of the fall - the uprising of layers and reservoir separately, . which is consistent with the notion of action in the nature of the convective mechanism of deformation and the formation of intrusions,
. Topic of Ph.D. thesis: "Tectonics, volcanism and the history of geological development of the West Verkhoyansk". Subject doctoral thesis: "Statistical studies of morphology and folding patterns of education (on the geological and experimental data)".
Lectured on the structural geology with elements of Tectonophysics and application of mathematics in geology, spent his student practice in the Crimea and Moscow, gave lessons on geotectonics.
He has published over 70 scientific papers in t.ch. 6 monographs. Major works: "Types, history and mechanism of folding of the Southeastern Caucasus" (al. H. B. Lebedev and VI Bashilov, 1966), "the Statistical regularities folding" (1977), "Methods of geological mapping and descriptions geolgicheskih routes Chashnikovskogo training ground" (co-author. H. V. Makarov, 1988).
