Download or read book Granites written by Anne Nédélec and published by OUP Oxford. This book was released on 2015-01-09 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: Granites are emblematic rocks developed from a magma that crystallized in the Earth's crust. They ultimately outcrop at the surface of every continent. This book offers a modern presentation of granitic rocks. It considers granites in their geological spatial and temporal frame, and in relation to plate tectonics and Earth history. The book - translated, edited, and updated from the original French edition Pétrologie des Granites published by Vuibert in 2011 - gives a modern presentation of granitic rocks, or granites, from magma genesis to their emplacement into the crust and their crystallization. Mineralogical, petrological, physical, and economical aspects are explored and developed in a succession. The text is supported throughout by a large number of illustrations, descriptions of modern techniques, and additional boxes holding further discussions for those wishing to deepen their knowledge of the subject.

This book was released on 2014-11-25 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bachelor Thesis from the year 2011 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: A, Abubakar Tafawa Balewa University (FACULTY OF SCIENCE), course: GEOLOGY, language: English, abstract: This work produces some vital geologic information on the geology and structural analysis of rocks mapped around Kanwara, Dass local government area of Bauchi State. The mapped area is located between longitude N10001’09” and N1O000’09”and latitude E9032’42” and E9031’26”. Exposure of rocks in the area were mostly high level and medium level outcrops with only a few low level outcrops, the high level outcrops were conically shaped with height ranging between 400m to 700m above sea level while the inselberg was about 900m. The predominant rock types in the area were granite gneiss, biotite granite and migmatite, under thin section, minerals were identified via their respective optical properties under both plane polarized light and cross polarized light, the major minerals associated with the rocks were; biotite, quartz, feldspars, (orthoclase & plagioclase), muscovite and microcline. Based on field observations, the geologic structures found on the rocks include; joints, foliations, minor folds, ghost schist, dykes and veins. The joints indicate the masking effect of the pan African orogeny on the older granites (trending NW-SE). The shape of the girdle from the structural analysis conducted indicates that the rocks of the mapped area were subjected to medium grade metamorphism.
Download or read book Landforms and Geology of Granite Terrains written by Charles Rowland Twidale and published by CRC Press. This book was released on 2005-05-26 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Granite is exposed over more than 15% of the continents, implying that its significance to the Earth’s surface is comparable to that of the carbonates. Landforms and Geology of Granite Terrains is devoted to this phenomenon and provides a comprehensive explanation of the landforms and landscapes developed on granitic rocks and forms. Whereas existing literature in the field predominantly deals with karst landscapes, this book is specifically focussed on granitic terrains. Landforms and Geology of Granite Terrains provides detailed considerations of the forms, major and minor, well-known and not so familiar granitic terrains, developed over large areas of the continents. It comprises interpretations which are of general significance in the analysis and understanding of the landscape and includes many theories in the context of granite landforms. The importance of structure, including crystal stresses, and the value of etching of subsurface initiation, multi-stages or two-stages development, neotectonic forms, solution forms is emphasized as well as the antiquity of some forms and surfaces (inherited forms). Morphogenetic forms are placed in perspective and comparison is made with similar forms in other rock types. This work is intended for geologists, geomorphologists, geographers and mining engineers and can serve both as a practical guide for professionals and as a textbook for university courses. Author, location and subject indices are included.

Available in PDF, EPUB and Kindle. Book excerpt: The origin of granite has for long fascinated geologists though serious debate on the topic may be said to date from a famous meeting of the Geological Society of France in 1847. My own introduction to the subject began exactly one hundred years later when, in an interview with Profes sor H. H. Read, I entered his study as an amateur fossil collector and left it as a committed granite petrologist - after just ten minutes! I can hardly aspire to convert my reader in so dramatic a way, yet this book is an attempt, however inadequate, to pass on the enthusiasm that I inherited, and which has been reinforced by innumerable discussions on the outcrop with granitologists of many nationalities and of many shades of opinion. Since the 1960s, interest in granites has been greatly stimulated by the thesis that granites image their source rocks in the inaccessible deep crust, and that their diversity is the result of varying global tectonic context. So great a body of new data and new ideas has accumulated that my attempt to review the whole field of granite studies must carry with it a possible charge of arrogance, especially as I have adopted the teaching device of presenting the material from a personal point of view with its thinly disguised prejudices.

This book was released on 2013-11-11 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: viii debate of those earlier days has been beautifully summarized by H. H. Read in his famous "Granite Controversy" (1957). Read's formulation of the controversy occurred at the time when geochemistry was as a new and powerful tool. The new techniques opened era during which emerging an granites were considered mainly from this new viewpoint. Geochemical signatures have shown that mantle and crustal origins for granites were both possible, but the debate on how and why granites are emplaced did not progress much. Meanwhile, structural geology was essentially geometrical and mechanistic. In the early 70's, the structural approach began to widen to include solid state physics and fluid dynamics. Detailed structural maps of granitic bodies were again published, mainly in France, and analysed in terms of magmatic and plastic flow. The senior editor of this volume and his students deserve much of the credit for this new development. Via microstructural and petrofabric studies, they were able to discriminate between strain in the presence of residual melt or in the solid-state, and, by systematically measuring magnetic fabrics (AMS), they have been able to map magmatic foliations and lineations in ever finer detail, using the internal markers within granites coming from different tectonic environments. The traditional debate has been shifted anew. The burning question now seems to be how the necessary, large-scale or local, crustal extension required for granite emplacement can be obtained.

Available in PDF, EPUB and Kindle. Book excerpt: A knowledge of structural geology is fundamental to understanding the processes by which the earth's crust has evolved. It is a subject of fundamental importance to students of geology, experienced field geologists and academic researchers as well as to petroleum and mining engineers. In contrast to many structural textbooks which dwell upon geometrical descriptions of geological structures, this book emphasises mechanical principles and the way in which they can be used to understand how and why a wide range of geological structures develop. Structures on all scales are considered but the emphasis of the book is on those that can be seen on the scale of hand specimen or outcrop. Drawing on their considerable teaching experience the authors present a coherent and lucid analysis of geological structures which will be welcomed by a wide variety of earth scientists.

Available in PDF, EPUB and Kindle. Book excerpt: Granites (sensu lato) represent the dominant rock-type forming the upper–middle continental crust but their origin remains a matter of long-standing controversy. The granites may result from fractionation of mantle-derived basaltic magmas, or partial melting of different crustal protoliths at contrasting P–T conditions, either water-fluxed or fluid-absent. Consequently, many different mechanisms have been proposed to explain the compositional variability of granites ranging from whole igneous suites down to mineral scale. This book presents an overview of the state of the art, and envisages future avenues towards a better understanding of granite petrogenesis. Particular emphasis of this Volume is on the following topics: Compositional variability of granitic rocks generated in contrasting geodynamic settings during Proterozoic to Phanerozoic Periods, Main permissible mechanisms producing subduction-related granites, Crustal anatexis of different protoliths, and the role of water in granite petrogenesis, New theoretical and analytical tools available for modelling whole-rock geochemistry, in order to decipher the sources and evolution of granitic suites.
