The article discusses regularities in the distribution of mud volcanoes and characterizes most important mud volcanic provinces of the world. A new morphogenetic classification of mud volcanoes substantiated by results of their study in the Crimean–Caucasian and West Turkmenian regions is proposed. 相似文献

It is shown that siderite is unstable during sedimentation, diagenesis, and metamorphism of sedimentary and volcanosedimentary rocks. Regularities in the distribution of siderite in Precambrian jaspilites (iron formations), metasomatic ores of the Bakal type, continental–marine coaliferous formations, and oolitic iron ores are discussed. The genesis of the Precambrian iron formations and Riphean–Lower Paleozoic elisional–hydrothermal deposits is considered. The genetic relation of nodular siderites from coaliferous formations and oolitic iron ores with lowmoor coal-forming peat deposits is noted. 相似文献

The composition and metallogeny of igneous rocks and relevant weathering crusts of Jurassic–Cretaceous provenances of the Russian Platform are considered. It is shown that the association of metals that accumulated in the process of weathering and erosion of ancient substratum includes P, Fe, Ti, V, and Cr. This process is reflected in the formation of nodular phosphorites, Ti and Zr placers, and iron ore deposits in the Jurassic–Cretaceous seas of the platform. 相似文献

The 3D MHD algorithm developed by us has been adapted to modeling the interaction between two plasma bunches in the ionosphere, mainly in order to sufficiently correctly describe the physics of the interaction between two plasma regions with regard to the ionospheric inhomogeneity and the geomagnetic field action. Modeling has been performed for several versions of location of the plasma region centers. 相似文献

The physicomathematical features of the plasma explosion region dynamics at altitudes higher than 100 km at the early stage of its development, which culminates in the transfer of a considerable portion of the initial plasma energy into the environment, are discussed in the first part of the work. The radiation gas dynamic, inertial, and shock stages of the disturbed region development are calculated. 相似文献

Evolution of N.M. Strakhov’s views on the formation of diagenetic sulfides in Holocene-Quaternary rocks of the Black Sea is
considered. It is shown that Strakhov actually discarded the statement of A.D. Arkhangel’skii about the migration of hydrotroilite
from the Drevnechernomorsk (i.e., ancient Black Sea sediments) to the Neoeuxinian sequence and attribute the generation of
sulfides in the hydrotroilite bed to the redox hydrosulfuric barrier. New data on sulfide distribution in Black Sea sediments
and concept of ancient Black Sea sediments as semipermeable membranes suggest the decisive role of hydrosulfuric solutions
in the generation of sulfide accumulations. 相似文献
