Umeshwar Prasad Economic Geology Pdf 138golkes

Economic geology is the branch of geology that deals with the study of economic minerals, their formation, distribution, extraction, and use. Economic minerals are those that have some value or utility for human society, such as metals, fuels, gemstones, industrial minerals, and construction materials. Economic geology also covers the environmental and social impacts of mineral exploitation, as well as the policies and regulations that govern the mineral sector.

One of the prominent authors in the field of economic geology is Umeshwar Prasad, a former professor of geology at Patna University, India. He has written several books and papers on various aspects of economic geology, such as mineral deposits, ore genesis, metallogeny, mineral exploration, and mineral economics. His book "Economic Geology: Economic Mineral Deposits" is a comprehensive and updated textbook that covers the full course of the subject for undergraduate and postgraduate students in geology. The book has been thoroughly rectified and revised as per needs.

The book has 12 chapters that cover the following topics:

  • Introduction: The purpose and scope of economic geology, the distribution of elements and minerals, and the definitions and classifications of mineral deposits.

  • Essential factors in mineral deposition and ore genesis: The physical and chemical conditions that control the formation of mineral deposits, such as temperature, pressure, fluid composition, pH, Eh, solubility, precipitation, crystallization, and adsorption.

  • Mineral paragenesis and zoning: The sequence and association of minerals in a deposit, the spatial distribution and variation of minerals and elements in a deposit, and the factors that influence them.

  • Metallogenetic epochs and provinces: The temporal and spatial patterns of mineral deposit formation in relation to geological events and processes, such as plate tectonics, magmatism, metamorphism, sedimentation, erosion, and weathering.

  • Controls of mineral localization: The geological features that influence the occurrence and concentration of minerals in a deposit, such as faults, fractures, folds, joints, bedding planes, igneous intrusions, volcanic vents, metamorphic aureoles, sedimentary basins, unconformities, and surface features.

  • Magmatic deposits: The mineral deposits that are formed by direct crystallization from magmas or by magmatic differentiation or segregation processes.

  • Hydrothermal deposits: The mineral deposits that are formed by the interaction of hot aqueous fluids with rocks or minerals.

  • Sedimentary deposits: The mineral deposits that are formed by mechanical or chemical processes during sedimentation or diagenesis.

  • Metamorphic deposits: The mineral deposits that are formed by recrystallization or remobilization of minerals during metamorphism.

  • Weathering deposits: The mineral deposits that are formed by alteration or enrichment of minerals during weathering or supergene processes.

  • Placer deposits: The mineral deposits that are formed by concentration of heavy minerals in sediments by water or wind action.

  • Mineral economics: The principles and methods of evaluating the economic viability and feasibility of mineral projects, such as demand and supply analysis, cost-benefit analysis, risk analysis, resource estimation, reserve classification, ore valuation, mine planning, mineral processing, marketing, taxation, royalty, legislation, and social responsibility.

The book also contains several tables, figures, diagrams, maps, photographs, examples, exercises, references, appendices, and an index to illustrate and supplement the text. The book is available in both print and digital formats .

The keyword "umeshwar prasad economic geology pdf 138golkes" is a combination of the author's name, the subject of his book, the file format of his book, and a suffix that indicates a pirated or illegal copy of his book. The suffix "golkes" is derived from the word "golki", which means "thief" or "robber" in Hindi. It is often used by online users to search for free downloads or torrents of books or other media that are otherwise protected by copyright or intellectual property rights. However, such practices are unethical and illegal and can have serious consequences for both the users and the authors. Users can face legal actions or malware infections from downloading or accessing such files, while authors can lose their revenue and reputation from having their work stolen or distributed without their consent.

Therefore, it is advisable to respect the rights and efforts of the authors and publishers and to purchase or access their books or media through legitimate and authorized sources. This way, users can enjoy the benefits of quality and reliable information and education, while authors can receive the recognition and reward that they deserve for their contribution to the field of economic geology.
