This book was released on 1990-02-28 with total page 635 pages. Available in PDF, EPUB and Kindle. Book excerpt: Featuring over 250 contributions from more than 100 earth scientists from 18 countries, The Encyclopedia of Igneous and Metamorphic Petrology deals with the nature and genesis of igneous rocks that have crystallized from molten magma, and of metamorphic rocks that are the products of re-crystallization associated with increases in temperature and pressure, mainly at considerable depths in the Earth's crust. Entries range from alkaline rocks to zeolite facies - providing information on the mineralogical, chemical and textural characters of rock types, the development of concepts and the present state of knowledge across the spectrum of igneous and metamorphic petrology, together with extensive lists of both commonly used and little used terms and bibliographies.

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.
Download or read book Petrology and Genesis of Igneous Rocks written by Alok K. Gupta and published by Narosa Publishing House. This book was released on 2007 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: Petrology and Genesis of Igneous Rocks comprises of two parts - the first part (Chapters 1 to 8) deals with constituent minerals, texture, thermodynamic principles, phase relations in natural rock systems and causes of diversity in a single petrographic province. Petrology of the crust, mantle and core, the convective cycle patterns in the mantle and their relation to magma genesis and physicochemical properties of magma are also discussed in this part. Use of Isotope geology in determination of age and degree of magma mixing is included towards the end of the first part. The second part (Chapters 9-13) describes individual rock types, from various countries including their geochemistry, petrology and genesis.

Download or read book Potassic Igneous Rocks and Associated Gold Copper Mineralization written by Daniel Müller and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potassic igneous rocks have gained much attention among petrologists worldwide, mainly due to their distinct geochemistry, and many geoscientists still consider them as petrological curiosities with an obscure petrogenesis. In the past, a plethora of genetic hypotheses and of local names for potassic igneous rocks from different localities have been created. This has produced some confusion in the literature. This book reviews the geochemical and petrological characteristics of the potassic igneous rock complexes and investigates the different tectonic settings in which these rocks occur. The authors provide an overview and a classification of these rocks and attempt to elucidate the geochemical differences between barren and mineralized potassic igneous complexes. Many epithermal gold and porphyry copper-gold deposits are hosted by high-K rocks. Therefore, this book is not only relevant to academic petrologists working on alkaline rocks, but also to exploration geologists prospecting for epithermal gold and/or porphyry copper-gold deposits in modern and ancient terranes. This third, updated and enlarged edition contains several new sections, new geochemical data and additional references.
Download or read book Rock Anisotropy and the Theory of Stress Measurements written by Bernard Amadei and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: Any undisturbed rock mass is subject to natural stresses inclu ding gravitational stresses due to the mass of the overburden and possibly tectonic stresses due to the straining of the earth's crust and remanent stresses due to past tectonism. Knowledge of the in situ stress field must be integrated into any rock engineering design along with general rock mass characteristics such as de for mability, strength, permeability and time dependent behavior. For example, the choice of optimum orientation and shape of deep underground caverns or complex underground works will be controlled by the orientation and the magnitude of the in situ stress @ield if it is necessary to minimize stress concentration problems. Long term variation of the in situ stress field may also help to evaluate the potential hazard of earthquake occurences. The magnitude and orientation of the stress field ata point within a rock mass can be measured but there is no known method by which the state of stress at a point can be accurately determined by instruments located remotely. In general, measurements are made inside boreholes, on outcrops or on the internal surfaces of under ground cavities. Most of the measuring techniques intentionally disturb the state of stress in the rock and then measure consequent strains and displacements. Measured strains or displacements are then related to the stresses through assumptions of material behavior. A common procedure is to assume that the rock mass is linearly elastic, isotropic, continuous and homogeneous.
Download or read book Magmas Rocks and Planetary Development written by Eric A. K. Middlemost and published by Routledge. This book was released on 2014-06-03 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: The variety of volcanic activity in the Solar System is widely recognised, yet the majestic sequences of magmatic processes that operate within an active planet are much less well known. Providing an exposition of igneous rocks, magmas and volcanic erupsions, this book brings together magnetic and volcanic data from different tectonic settings, and planets, with explanations of how they fit together. It systematically examines composition, origin and evolution of common igneous rocks, yet also examines a variety of rare magnetic rocks that play a crucial role in the global magma/igneous rock system.
