Available in PDF, EPUB and Kindle. Book excerpt: In this book, the first dedicated entirely to the petrology of lamproites and their relationships to other potassium-rich rocks, the objective of the authors is to provide a comprehensive critical review of the occurrence, mineralogy, geochemistry, and petrogenesis of the clan. Although lamproites represent one of the rarest of all rock types, they are both economically and scientifically important and we believe the time is ripe for a review of the advances made in their petrology over the past two decades. Many of these advances stem from the recognition of diamond-bearing lamproites in Western Australia and the reclassification of several anomalous diamond-bearing kim berlites as lamproites. Consequently lamproites, previously of interest only to a small number of mineralogists specializing in exotica outside the mainstream of igneous petrol ogy, have become prime targets for diamond exploration on a worldwide basis. Contemporaneously with these developments, petrologists realized that lamproites possess isotopic signatures complementary to those of midoceanic ridge basalts, alkali basalts, kimberlites, and other mantle-derived melts. These isotopic studies provided new insights into the long-term development of the mantle by suggesting that the source regions of lamproites were metasomatically enriched in light rare earth and other incompatible elements up to 1-2 Ga prior to the melting events leading to generation of the magma.

This book was released on 2021-06-09 with total page 802 pages. Available in PDF, EPUB and Kindle. Book excerpt: This memoir is the first to review all of Antarctica’s volcanism between 200 million years ago and the Present. The region is still volcanically active. The volume is an amalgamation of in-depth syntheses, which are presented within distinctly different tectonic settings. Each is described in terms of (1) the volcanology and eruptive palaeoenvironments; (2) petrology and origin of magma; and (3) active volcanism, including tephrochronology. Important volcanic episodes include: astonishingly voluminous mafic and felsic volcanic deposits associated with the Jurassic break-up of Gondwana; the construction and progressive demise of a major Jurassic to Present continental arc, including back-arc alkaline basalts and volcanism in a young ensialic marginal basin; Miocene to Pleistocene mafic volcanism associated with post-subduction slab-window formation; numerous Neogene alkaline volcanoes, including the massive Erebus volcano and its persistent phonolitic lava lake, that are widely distributed within and adjacent to one of the world’s major zones of lithospheric extension (the West Antarctic Rift System); and very young ultrapotassic volcanism erupted subglacially and forming a world-wide type example (Gaussberg).

Book excerpt: A photographic and multidisciplinary study of one of America’s last undeveloped—and most endangered—landscapes, edited by a Pulitzer Prize–winning author. A vast expanse of rock formations, sand dunes, and sagebrush in central and southwest Wyoming, the little-known Red Desert is one of the last undeveloped landscapes in the United States, as well as one of the most endangered. It is a last refuge for many species of wildlife. Sitting atop one of North America's largest untapped reservoirs of natural gas, the Red Desert is a magnet for energy producers who are damaging its complex and fragile ecosystem in a headlong race to open a new domestic source of energy and reap the profits. To capture and preserve what makes the Red Desert both valuable and scientifically and historically interesting, writer Annie Proulx and photographer Martin Stupich enlisted a team of scientists and scholars to join them in exploring the Red Desert through many disciplines: geology, hydrology, paleontology, ornithology, zoology, entomology, botany, climatology, anthropology, archaeology, sociology, and history. Their essays reveal many fascinating, often previously unknown facts about the Red Desert—everything from the rich pocket habitats that support an amazing diversity of life to engrossing stories of the transcontinental migrations that began in prehistory and continue today on I-80—which bisects the Red Desert. Complemented by Martin Stupich’s photo-essay, which portrays both the beauty and the devastation that characterize the region today, Red Desert bears eloquent witness to a unique landscape in its final years as a wild place./

Download or read book Road from Geochemistry to Geochemometrics written by Surendra P. Verma and published by Springer. This book was released on 2019-08-16 with total page 675 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights major problems in the statistical analysis of compositions that have been known for over a century, as well as the corresponding solutions that have been put forward by specialists over the past 30 years. The basic assumptions of normality or multi-normality are pointed out and methods to test and achieve them are also covered. The conventional major and trace element geochemistry and modeling equations are discussed, and are followed by a more sophisticated multidimensional approach to data handling. The book’s main focus is on the use of statistical techniques to facilitate data interpretation. It also highlights the classification (or nomenclature) and tectonic discrimination aspects for both igneous and sedimentary rocks. The book concludes by discussing computer programs that are helping pave the way from geochemistry to geochemometrics. Written by a leading expert in the area of geochemistry, it offers a valuable guide for students and professionals in the area.
