Available in PDF, EPUB and Kindle. Book excerpt: La 4e de couv. indique : "The concept of plate tectonics is relatively new - it was only in the 1960s that the idea that continents drifted with respect to one another came to be accepted. Plate tectonics now forms one of geology's basic principles and explains much of the large-scale structure and phenomena we see on Earth today. In this Very Short Introduction Peter Molnar explores the impact that plate tectonics has had on our understanding of Earth : how the ocean floor forms, widens, and disappears ; why earthquakes and volcanoes are found in distinct zones ; and how the great mountain ranges of the world were built. As the Himalaya continues to grow, the Atlantic widens, and new ocean floor is forming, the mechanisms of plate tectonics continue to alter the surface of our planet."

This book was released on 1983 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: To assist in the assessment of the geothermal potential of north-central California and to aid in defining the geologic transitions between the physiographic provinces of the Klamath Range, the Cascade Range, the Modoc Plateau, the Great Valley, and the Sierra Nevada Range, personnel from the Geophysics Group in the College of Oceanography at Oregon State University conducted a detailed aeromagnetic survey extending from 40°15' to 42°00'N latitude and from 120°45' to l22°45'W longitude. Two forms of spectral analysis, the energy spectrum and the exponential methods, were used to make source-top and source-bottom depth calculations. The magnetic source-bottom depths were interpreted as Curie-point isotherm depths. Based on the energy spectrum analysis, several regions with elevated Curie-point isotherm depths were mapped: (1) the Secret Spring Mountain-National Lava Beds Monument area, (2) the Mount Shasta area, (3) the Big Valley Mountains area, and (4) an area northeast of Lassen Peak. The elevated Curie-point isotherm depths within these areas, as shallow as 4 to 7 km below sea level (BSL) in the Secret Spring Mountain-National Lava Beds Monument area, the Mount Shasta area, and the area northeast of Lassen Peak, and 4 to 6 km BSL in the Big Valley Mountains area, imply vertical temperature gradients in excess of 70°C/km and heat flow greater than 100 mW/m2 when assuming a Curie-point temperature of 580°C. Shallow source-bottom depths of 4 to 5 km BSL were mapped in the Eddys Mountain area and interpreted to be the depth of a lithologic contact. Source-top depths show that the magnetic basement varies from about 3.5 km BSL, beneath the sedimentary assemblages of the Great Valley and the eastern Klamath Range, to near sea level in the Cascade Range. The exponential approximation method yielded source-bottom depths which agreed, in general, with depths determined by the energy spectrum method. However, this method appears less reliable and its depth estimates less accurate compared to the energy spectrum method. A broad negative anomaly, observed on the total field magnetic intensity map and low-pass filtered anomaly maps, suggests the sedimentary rocks of the Klamath Complex underlie Mount Shasta and the Medicine Lake Highlands. Magnetic lineations are oriented mainly NW.

Available in PDF, EPUB and Kindle. Book excerpt: This volume provides an overview of (1) the physical and chemical foundations of dating methods and (2) the applications of dating methods in the geological sciences, biology, and archaeology, in almost 200 articles from over 200 international authors. It will serve as the most comprehensive treatise on widely accepted dating methods in the earth sciences and related fields. No other volume has a similar scope, in terms of methods and applications and particularly time range. Dating methods are used to determine the timing and rate of various processes, such as sedimentation (terrestrial and marine), tectonics, volcanism, geomorphological change, cooling rates, crystallization, fluid flow, glaciation, climate change and evolution. The volume includes applications in terrestrial and extraterrestrial settings, the burgeoning field of molecular-clock dating and topics in the intersection of earth sciences with forensics. The content covers a broad range of techniques and applications. All major accepted dating techniques are included, as well as all major datable materials.

Download or read book Caribbean Basins written by P. Mann and published by Elsevier. This book was released on 1999-12-15 with total page 713 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 21-chapter volume provides a regionally-comprehensive collection of original studies of Caribbean basins conducted by academic and petroleum geologists and geophysicists in the early and mid-1990s. The common tectonic events discussed in the volume including the rifting and passive margin history of North and South America that led to the formation of the Caribbean region; the entry of an exotic, Pacific-derived Great Arc of the Caribbean at the leading edge of the Caribbean oceanic plateau; the terminal collision of the arc and plateau with the passive margins fringing North and South America; and subsequent strike-slip and accretionary tectonics that affected the arc-continent collision zone.Two introductory chapters (Part A) utilize recent advances in quantitative plate tectonic modeling and satellite-based gravity measurements to place the main phases of Caribbean basin formation into a global plate tectonic framework. Nineteen subsequent chapters are organized geographically and focus on individual or groups of genetically-linked basins. Part B consists of five chapters which mainly focus on basins overlying the North America plate in the Gulf of Mexico, Cuba and the Bahamas that record its rifting from South America in late Jurassic to Cretaceous time. Part C has six chapters that focus on smaller, usually heavily faulted and onshore Cenozoic basins of the northern Caribbean that formed in response to arc collisional and strike-slip activity along the evolving North America-Caribbean plate boundary. The two chapters in Part D focus on Cenozoic basins related to the Lesser Antilles arc system of the eastern Caribbean. Part E is comprised of three chapters on the Jurassic-Recent sedimentary basins of the eastern Venezuela and Trinidad area of the southeastern Caribbean. These basins reflect both the Jurassic-Cretaceous rifting and passive margin history of separation between the North and South America plates as well as a much younger phase of Oligocene to recent transpression between the eastward migrating Lesser Antilles arc and accretionary wedge and the South America continent. The three chapters of Part F contain deep penetration seismic reflection and other geophysical data on the largely submarine Cretaceous Caribbean oceanic plateau that forms the nucleus of the present-day Caribbean plate.

Download or read book Fine-scale Topography and Magnetic Anomalies of the Deep Sea Floor Off Southern California written by Michael Samuel Loughridge and published by . This book was released on 1967 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first survey of a portion of the Pacific sea floor by means of deeply towed instruments was made in July 1965. The area surveyed off California near 123 deg 10 min W and 32 deg 40 min N was previously thought to be one of typical abyssal hills at a depth of approximately 4000 meters. Observations of the fine-scale topography and total magnetic field intensity were made with a narrow-beam echo-sounder and proton magnetometer towed within 300-500 meters of the sea floor. These observations show that the topography exhibits a linear trend in a direction which parallels the well-known Mason-Raff magnetic trends. In a direction perpendicular to this trend, the topography has a gently undulatory character with a recurrence wavelength of approximately 0.4 sq km and relief of approximately 100 meters. Speculative interpretations of the topography and magnetics are given which discuss their origin, preservation, and possible relationships to other crustal features. Instrumentation and acoustic navigation techniques are also described. (Author).

Download or read book Petroleum Geology of the Black Sea written by M.D. Simmons and published by Geological Society of London. This book was released on 2018-08-14 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Black Sea remains one of the largest underexplored rift basins in the world. Future success is dependent on a better understanding of a number of geological uncertainties. These include reservoir and source rock presence and quality, and the timing of migration of hydrocarbons relative to trap formation. An appreciation of the geological history of the Black Sea basins and the surrounding orogens is therefore key. The timing of basin formation, uplift of the margins, and of facies distribution remain issues for robust debate. This Special Publication presents the results of 15 studies that relate to the tectono-stratigraphy and petroleum geology of the Black Sea. The methodologies of these studies encompass crustal structure, geodynamic evolution, stratigraphy and its regional correlation, petroleum systems, source to sink, hydrocarbon habitat and play concepts, and reviews of past exploration. They provide insight into the many ongoing controversies concerning Black Sea regional geology and provide a better understanding of the geological risks that must be considered for future hydrocarbon exploration.
