Добрый день, Коллеги. Важное сообщение, просьба принять участие. Музей Ферсмана ищет помощь для реставрационных работ в помещении. Подробности по ссылке
В работе рассматриваются актуальные вопросы постметаморфической эволюции кристаллического фундамента центральной структуры Востока Русской плиты — Татарского свода. Основное внимание при этом сосредоточено на геологическом изучении и структурно-вещественной характеристики специфических образований больших глубин — зон деструкций, вскрытых глубокими и сверхглубокими скважинами, пробуренными на территории Татарского свода и его обрамления.
In the study of the geodynamics of passive continental margins greatest emphasis has been placed on the evolution of the crystalline crust and deeper rocks. Contributions from detailed studies of the sedimentary succession have perhaps played a smaller, but nonetheless important role in determining the mechanisms of evolution. As a consequence, this review concentrates on the crystalline rocks, only mentioning the important aspects of the sediments in passing.
This paper address the question of why giant gold deposits are so unevenly spread over the continents, what processes control their distribution, and how more might be found? Using the source-migration-trap paradigm, it is proposed that the regional distribution of gold deposits is controlled by fluid access to gold sources on a regional scale, and by large-scale migration mechanisms.
All information about the Earth’s interior comes from field observations and measurements made within the top few kilometers of the surface, from laboratory experiments and from the powers of human deduction, relying on complex numerical modeling. Solid Earth Geophysics encompasses all these endeavors and aspires to define and quantify the internal structure and processes of the Earth in terms of the principles of physics, corresponding mathematical formulations and computational procedures.
