Download or read book Coarse Grained Deltas written by Albina Colella and published by John Wiley & Sons. This book was released on 2009-03-30 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Special Publication contains most of the contributions presented at the 1st International Workshop on Fan Deltas (1988) but also contains additional papers which make this particular volume a very well-rounded reference source for the advanced undergraduate/graduate student and the professional earth scientist concerned with sedimentology and petroleum geology. The papers describe the sedimentology and tectonic setting of this important depositional environment. Course-grained deltas, ranging from sand to gravelly, are fully covered and the main focus is on steep-face systems whose steep subaqueous slopes are dominated by high-energy processes. The volume includes case histories from around the world and throughout the book there is emphasis on the subaqueous realm of the delta face, its sedimentary processes and facies associations

This book was released on 2012-12-06 with total page 705 pages. Available in PDF, EPUB and Kindle. Book excerpt: by K. Lambeck, R. Sabadini and E. B08Chi Viscosity is one of the important material properties of the Earth, controlling tectonic and dynamic processes such as mantle convection, isostasy, and glacial rebound. Yet it remains a poorly resolved parameter and basic questions such as whether the planet's response to loading is linear or non-linear, or what are its depth and lateral variations remain uncertain. Part of the answer to such questions lies in laboratory observations of the rheology of terrestrial materials. But the extrapolation of such measurements from the laboratory environment to the geological environment is a hazardous and vexing undertaking, for neither the time scales nor the strain rates characterizing the geological processes can be reproduced in the laboratory. General rules for this extrapolation are that if deformation is observed in the laboratory at a particular temperature, deformation in geological environments will occur at a much reduced temperature, and that if at laboratory strain rates a particular deformation mechanism dominates over all others, the relative importance of possible mechanisms may be quite different at the geologically encountered strain rates. Hence experimental results are little more than guidelines as to how the Earth may respond to forces on long time scales.
