This book was released on 2012 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study investigates the effect of data density on the calculation of cave passage volume for hypogene flank margin caves. Four cave passages on San Salvador, Bahamas, were surveyed using a high density, radial-surveying technique. The data sets were used to calculate cross-sectional areas of passages at multiple locations along a survey transects. Using the entire data set, total passage volumes were computed and then compared to reduced data sets to characterize the effect morphology had on area and volume determinations. Three cave passages were measured using 17 survey stations per transect and one passage was measured with 33 survey stations. Adjacent stations divide the passage into slabs. Summing the volume of the slabs yields total passage volume. A total of 2,688 measurements were taken in the four passages. The measurements were used in a series of analyses to study the errors associated with employing depleted data sets of 4, 8, and 16-point radial data sets to calculate area and total passage volume. These errors were then correlated with certain morphological traits common throughout the passages. Longitudinal data points (entire survey stations) were also depleted to study the effect this had on calculating total volume. The data reveals highly inaccurate area and slab volume values using depleted data sets and the sector method. Volume errors as high as 400% were present using 4 and 8-point radial data sets. Not until data sets of at least 16-points were employed, did the range in error decrease to within 50% difference. This indicates that hypogenic flank margin cave passages require high density data sets to accurately characterize their void space. This is in contrast to findings from epigene caves. Previous research in epigene caves suggest that the 4-point method and sector technique may be adequate for certain surveys. One similarity seen between epigene and hypogene data was the relative importance of radial data over longitudinal data. Both types of caves show larger errors in calculated volume when radial data points are depleted rather than depleting entire survey stations. The experiment also examined shapes other than the sector method for modeling cross-sectional area. Using a rectangle, cross-sectional area and total passage volume are reduced to within 60%. All three alternative models return errors less than 70%. These shapes are more accurate than the sector technique in calculating cross-sectional area, and therefore, total passage volume. Alternative shapes for modeling cross-sectional area allow the flexibility to selectively choose a model based on specific projects. The original sector technique should not be regarded as inadequate or inaccurate, but rather as not appropriate for every type of survey or project. These advances in modeling techniques improve our understanding of mega-porosity and subsurface void space.

Download or read book Hypogene Karst Regions and Caves of the World written by Alexander Klimchouk and published by Springer. This book was released on 2017-08-17 with total page 903 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book illustrates the diversity of hypogene speleogenetic processes and void-conduit patterns depending on variations of the geological environments by presenting regional and cave-specific case studies. The cases include both well-known and newly recognized hypogene karst regions and caves of the world. They all focus on geological, hydrogeological, geodynamical and evolutionary contexts of hypogene speleogenesis. The last decade has witnessed the boost in recognition of the possibility, global occurrence, and practical importance of hypogene karstification (speleogenesis), i.e. the development of solutional porosity and permeability by upwelling flow, independent of recharge from the overlying or immediately adjacent surface. Hypogene karst has been identified and documented in many regions where it was previously overlooked or misinterpreted. The book enriches the basis for generalization and categorization of hypogene karst and thus improves our ability to adequately model hypogene karstification and predict related porosity and permeability. It is a book which benefits every researcher, student, and practitioner dealing with karst.

Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1989, Karst Geomorphology and Hydrology became the leading textbook on karst studies. This new textbook has been substantially revised and updated. The first half of the book is a systematic presentation of the dissolution kinetics, chemical equilibria and physical flow laws relating to karst environments. It includes details of the many environmental factors that complicate their chemical evolution, with a critique of measurement of karst erosion rates. The second half of the book looks at the classification system for cave systems and the influence of climate and climatic change on karst development. The book ends with chapters on karst water resource management and a look at the important issues of environmental management, including environmental impact assessment, environmental rehabilitation, tourism impacts and conservation values. Practical application of karst studies are explained throughout the text. "This new edition strengthens the book's position as the essential reference in the field. Karst geoscientists will not dare to stray beyond arm's reach of this volume. It is certain to remain the professional standard for many decades." Journal of Cave and Karst Studies, August 2007

Book excerpt: There are three types of rock—igneous, metamorphic and sedimentary. Sedimentary rocks form from the weathering, erosion, transportation and deposition of older rocks. Applied Sedimentology describes the formation, transportation and deposition of sediment, and the post-depositional processes that change soft sediment into sedimentary rock. Sedimentary rocks include sandstones, limestones and mudstones. All the world's coal, most of its water and fossil fuels, and many mineral deposits occur in sedimentary rocks. Applied Sedimentology shows how the study of sediments aids the exploration for and exploitation of natural resources, including water, ores and hydrocarbons. * Completely revised edition; Like its precursor, it describes sediments from sand grains to sedimentary basins; Features up-to date account and critique of sequence and cyclostratigraphy * Extensively illustrated with photos and remotely sensed sea bed images describing sedimentary processes, products and depositional systems; Color plates illustrate sediment textures, lithologies, pore types, diagenetic textures, and carbonate and clastic sequence stratigraphic models* Emphasises the applications of sedimentology to the exploration for and exploitation of natural resources, including water, ores and hydrocarbons* Extensive references and up-to-date bibliography for further study

Book excerpt: Anyone who has marveled at the glimmer of a perfectly cut diamond, tended a garden, or consumed a nutritious meal has appreciated some of the many roles that minerals play in our lives. Present in many natural substances, minerals are highly structured entities, each with a unique chemical composition and set of properties. Accompanied by detailed tables, diagrams, and sidebars, this informative volume examines the various types of minerals and their structures and classifications, as well as the physical and chemical attributes that separate one mineral from another.

This book was released on 2004 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the first systematic discourse on a very peculiarapproach to the theory of strongly correlated systems. HubbardX-operators have been known for a long time but have not been widelyused because of their awkward algebra. The book shows that it ispossible to deal with X-operators even in the general multilevel localeigenstate system, and not just in the case of the nondegenerateHubbard model. X-operators provide the natural language for describingquasiparticles in the Hubbard subbands with unusual doping andtemperature-dependent band structures.
