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.

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.

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.

This book was released on 2023-01-09 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the second volume of an edited work aiming to help novice geologists to explore terrains independently. Geoscience fieldwork with focus on structural geology and tectonics has become more important in the last few years from both academic and industrial perspectives. This book also works as a resource material for batches of students or geological survey professionals undergoing training as parts of their course curriculum/training. Industry persons, on the other hand, can get a first-hand idea about what to expect in the field, in case no academic persons are available with the team. This book focuses on structural geology and tectonics and compiles terrains from several regions of the globe. This book also includes field guide chapters for primary sedimentary structures.
Download or read book Analysis of Geological Structures written by Neville J. Price and published by Cambridge University Press. This book was released on 1990-08-16 with total page 524 pages. 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.

Download or read book Granite Landforms written by C.R. Twidale and published by Elsevier. This book was released on 2012-12-02 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Granite Landforms provides a systematic, coherent, and comprehensive account and analysis of granite landforms. It examines granite forms and their genesis; the morphology of granite exposures; the nature of the materials from which granitic rocks have evolved; and the weathering processes near the Earth’s surface. It also describes major landforms and assemblages, as well as the minor features that have evolved on the major hosts. Organized into four parts encompassing 12 chapters, this book begins with an overview of granite, including their characteristics, occurrences, and composition. It then discusses the factors that influence the weathering of granitic rocks and considers boulders and inselbergs, the all-slopes topography in granite, granite plains and rock basins, granite forms associated with steep slopes, and scarp foot depressions. The reader is also introduced to the piedmont angle, grooves or flutings, caves and tafoni, split rocks, cracked blocks and plates, and the role of climate in the development of landforms on granitic outcrops. Geologists, geomorphologists, geology students, and anyone interested in geology will find this book extremely useful.
