Translated from Russian, this text looks at the development of the earth's crust in the Palaeozoic period and starts from the Vendian to the Late Cambrian period. Moving on to include Ordovician to the mature stage of Caledonian and initial stage of development of Hercynian mobile belts; Silurian-Early Devonian. The completion of development of the Caledonian and early, mature and end stages of the Hercynian mobile belts; the birth of Cimmerian mobile belts and ending with the Palaeozoic.
Examines the structural evolution of the Earth's crust from the Triassic period to the present. The book describes the patterns of distribution, and the composition and accumulation conditions of formations in the various geological periods in all the continents and oceans.
Geotectonics has a special place among the geological dis ciplines. In addition to ideas based on firmly established facts that constitute lasting scientific values, geotectonics, as a generalizing branch of geology, embraces broad con structions that link the planet's deep interior with its sur face and are largely of a hypothetical character. The inter pretation of the most general matters of the structure and evolution of the globe varies not only from one generation of geologists to another, but even within one generation. The interpretation depends not only, and not so much, on the state of geological knowledge, as on the progress of the related sciences of geophysics and geochemistry. In trying to discover the deep-lying causes of tectonic processes, geotectonics has to unite the results of all the Earth sci ences, converting itself to some extent from a purely geologi cal science into a general physical geographic or geonomic science. The fluidity of the general ideas and the need for joint consideration of the geological, geophysical, and geochemi cal data to substantiate these ideas are the main difficulties facing the author of a textbook on geotectonics. There is undoubtedly, however, a need for a manual of this kind, particularly now when the literature on the various problems of geotectonics has grown so great and so varied in content that it is very difficult for the experienced researcher, let alone the student, to find his way.
The most comprehensive and in-depth study of the formation, practical applications, history, and natural recycling of salt, including the global and geological implications of its formative process, natural movement, and development in the Earth's subsurface. Like water, salt is one of the most commonplace items in our everyday lives. From the omnipresent shaker that you see on every table in every restaurant, to the ocean water we swim in, salt is something that we rarely think about. But there is much more to the story of salt than most people think. Not only is salt a natural resource that must be captured and refined for public consumption, but "salt domes," large deposits of salt that form under the ground, are important for finding and drilling for petroleum and natural gas. Salt is so important that, in ancient times, it was sometimes used as a currency in various cultures around the world, and it has been used as a food preservative, long before refrigeration was invented. Salt is something we rarely think about, but it is one of the most important natural resources that exists. This is the first integrated study of salt's global development in the Earth's subsurface, its tectonic history and kinematic evolution, "live" salt-naphtide interconnections, and their geological recycling. The Earth's salt is shown as a peculiar umbilical thread in the analysis of numerous geological processes of salt formation, transformation, migration, discharge and regeneration, and their association with hydrocarbons. Presented here is the science of salt, including the active salt bodies' "live" in Earth's subsurface, their fate and influence over the other geological processes, including grandiose systems of kinetically interrelated allochthonous nappe-like and sub-vertical bodies formed by the migrating salt. Also included are a description of sub-conformable sheet-like salt bodies formed not by the evaporation but by emigration of buried brine-salt masses and their discharge at new, younger stratigraphic levels, a description of a phenomenon of the "halo-volcanism" due to depth breakthroughs and explosive discharges of the hydrocarbon-brine-salt masses, an examination of the over-diapir surface and brine lakes with fluctuating levels, and many other things. The book provides new interpretations of numerous issues reflecting the salt "life" manifestations and gives a key to a broad circle of the geological enigmas, from global events like the Messinian crisis in the Mediterranean to Biblical legends and enigmas of the Dead Sea-lake. Whether you are a scientist or student working in the natural or Earth sciences, a geologist, an anthropologist, a petroleum engineer, a petrophysicist, or any other engineer or student working in petroleum engineering, this groundbreaking work is a must-have. Perfect for any scientist or engineer's library, this volume can be a must-read page-turner or a valuable reference work.
Examination of the continental shelf (Bering Sea) between Alaska and the Soviet Far East, to determine its geological structure, and the Tertiary geology of the strike-slip faults, arc-trench systems and basins of the region.
This is the third volume in The Oxford Regional Environments series. The series volumes are devoted to major regions of the world, each presenting a detailed and up-to-date body of scientific knowledge concerning a particular region. For most topics on the physical geography of Northern Eurasia abundant literature now exists. Most of it, however, is in Russian and other East European languages and this has significantly limited the number of potential readers. This volume seeks to familiarize, at an international level, those with an interest in this area with the most significant achievements in classical and current geographical research. The Physical Geography of Northern Eurasia covers most of the territory of the former USSR. The first section discusses the individual compenents of the physical environment. These chapters cut across regional boundaries and treate the area discussed as a whole. A regional analysis follows mainly in the context of geographical zonation, though a number of specific regions are given individual treatment. The concluding chapters discuss the effects of anthropogenic activities on the physical environment. The approach is an integrative one, tying together various aspects of the physical environments with the environmental implications of human activites. Every component of the environment is treated as a step in the development of the multi-faceted landscapes which in turn provide possibilities and limitations for cultural and economic usage.
Sequence stratigraphy has advanced considerably since the early applications of the concepts on seismic data. It attempts to discern the migration of facies re sulting from changes in a combination of factors such as, sea level, tectonics, climate and sediment flux, and integrates it with a meaningful chronostratigraphy. The stratigraphic record is envisioned as a framework of repetitive packages of genetically-related strata, formed in response to the shifting base level, in which the locus of deposition of various sediment types may be anticipated. This attribute is rapidly promoting sequence stratigraphy as an indispensable tool for prediction of facies in exploration and production geology. In hydrocarbon exploration the application of sequence stratigraphy has ranged from anticipating reservoir- and source-rock distribution to predicting carbonate diagenesis, porosity and permeability. The capability to anticipate vertical and lateral distribution of facies and reservoir sands in the basinal, shoreface, incised valley-fill and regressive settings alone has been a great asset for exploration. In frontier areas, where data are often limited to seismic lines, sequence-stratigraphic methodology has helped determine the timing and of types of unconformities and anticipate transgressive- and regressive-prone intervals. In production it is aiding in field development by providing improved source and seal predictions for secondary oil recovery. A recognition of stratigraphic causes of poor recovery through improved understanding of internal stratal architecture can lead to new well recompletions and enhanced exploitation in existing fields. The sequence-stratigraphic discipline is in a state of rapid expansion.
Transform margins form a significant portion of Earth’s continent–ocean transition and are integral to continental break-up, yet compared to other margins are poorly understood. This volume brings together new multidisciplinary research to document the structural, sedimentological and thermal evolution of transform margins, highlighting their relationship to continental structure, neighbouring oceanic segments, pull-apart basins and marginal plateaus. Special emphasis is given to the comparison of transform and rifted margins, and to the economic implications of transform margin structure and evolution. Transform case studies include the Agulhas–Falkland transform, Coromandal transform (East India), Davie margin and Limpopo transform (East Africa), Guyana transform margin, Demerara transform margin (Suriname), Romanche and St Paul transforms (equatorial Africa), Sagaing transform (Andaman Sea) and Zenith–Wallaby–Perth transform (West Australia). The broad-scale interplay between transform and rifted margin segments in the North and Central Atlantic, and Caribbean, is also examined.
