Chemistry of minerals, crystals and gems Books

Book SynopsisThe book is divided into four sections, minerals, crystals, rocks and ores. Section A incorporates nine s, begins with presenting salient features of the earth--its structure and composition. The second Minerals and Mineralogy briefly tells about their diversity and their categorisation and introduces the interesting way they are named. Crystal chemistry the third is the heart and soul of mineralogy and deals in somewhat details about the building blocks of minerals -atoms and ions and the way they form diverse types of minerals are. It tries to tell why every combination of chemical compounds cannot result into a naturally occurring mineral. The fourth and fifth s deal with Properties of Minerals, physical and optical. The s describe various physical properties that are helpful in the identification both in hand specimens and as thin section under the microscope. These two s are adequately aided with a number of illustrations, photographs and photomicrographs to bring home the point. five deals with classification of minerals and their occurrence and forms a prelude to the next two s on descriptive mineralogy. Important silicate and non silicate minerals are described in s eight and nine. A brief description of mineral uses is dealt with in both descriptive mineralogy as well Section D on mineral deposits, however, the last , Mineral uses presents an overall picture and will be interesting as well as educating to students and even general readeSection B is devoted to crystals and crystallography. one introduces the subject while two presents basic crystallographic elements. three deals with the main six crystals systems while also giving a preliminary idea about stereographic projection and x-ray crystallography. Section C covers petrology, beginning with introduction to science of petrology, rock nomenclature. two is devoted to the study of igneous rocks, including their forms, composition, textures, structures, classification and description. Sedimentary rocks is the theme of three while different aspects of metamorphic rocks including kinds and agents of metamorphism and classification and description of metamorphism. The last portion of this also considers metamorphism in the background of global tectonics. five, the rock cycle presents a concise summary of geological events that have shaped the planet earth. The last section D is what geology is all about for a man on the street and its significance in nation building--the Ore minerals. It begins with what ore is and its place in human affairs as a well as presenting the important terminology in economic geology. two deals with ore genesis and presents various hypogene and supergene process that carves out ore deposits from non economic materials. three, mineral deposits and global tectonics is becoming a very popular theme among the earth scientists. A brief introduction of the same will be certainly appreciated by the student community and prompt them for further study in this direction. A general survey of India's mineral resources is the theme of four. It covers almost all of the commonly used ores, metallic, non metallic or fuels. The last of section D and the boom, 'Indian mineral industry: some facts and figures' will present where our country stands in the realm of mineral resources. Latest available data of resources, production, export, import, organisations that matter and other useful facts and figures are presented.Table of ContentsSection I - Minerals: 01: The earth, 02: Minerals and mineralogy, 03: Elements of crystal chemistry, 04: Physical properties of minerals, 05: Optical properties of minerals, 06: Minerals: their classification and occurrence, 07: The silicate minerals, 08: The non-silicate minerals, 09: Mineral uses Section II - Crystals: 01: Introduction, 02: Elements of crystallography, 03: The six crystal systems, 04: Preliminary ideas on stereographic projection and x-ray crystallography Section III - Rocks: 01: Introduction, 02: Igneous rocks, 03: Sedimentary rocks, 04: Metamorphic rocks, 05: The rock cycle.

Book SynopsisThis book is the first systematic treatise of available data and view-points obtained from geological and geochemical studies of the Mo deposits in Qinling Orogen, China. Qinling Orogen has a minimum reserve of 8.7 Mt Mo, ranking the largest molybdenum province both in China and the world. Incorporating all known Mo deposit types in the world, it presents extensive studies of Mo deposits of world-class and unusual types within tectonic settings. The Qinling Orogen was finally formed during continental collision between Yangtze and North China cratons, following the Triassic closure of the northernmost paleo-Tethys. It hosts 49 Mo deposits formed in seven mineralization events since 1850 Ma, with all the world-class deposits being formed during 160-105 Ma, coeval with collisional orogeny. These deposits are assigned to magmatic and metamorphic hydrothermal classes. The magmatic hydrothermal class includes porphyries, skarns, and intrusion-related veins (carbonatite, fluorite and quartz). The porphyry Mo systems in Qinling Orogen are predominated by Dabie-type formed in continental collision setting, followed by Endako- and Climax-types formed in continental arcs and rifts, respectively. The metamorphic hydrothermal Mo deposits are only reported in Qinling Orogen, and thus a new crustal continuum model for the orogenic class mineral systems is proposed. A scientific linkage between ore geology and fluid inclusions is introduced and verified both by theory and case studies. This is the first research book comprehensively displaying continental collision metallogeny. This literature will benefit both Western and Chinese mineral explorers and miners, as well as research scientists and students.Table of ContentsChapter 1 Geological background Abstract 1.1 Introduction 1.1.1 Tectonic location and framework 1.1.2 Inventory of main ore types and commodities 1.2 Formation and geology of Qinling Orogen 1.2.1 Outline 1.2.2 Formation and geotectonic evolution of the Qinling Orogen 1.2.3 Major geologic events in the Qinling Orogen 1.3 Basement formation in southern North China Craton 1.3.1 Multi-terrane structure of SNCC 1.3.2 Qingyanggou-type greenstone belt and the primitive crust 1.3.3 Beizi-type greenstone belt and Shipaihe Complex: continental nuclei 1.3.4 The Junzhao and Dangzehe greenstone belts 1.3.5 Rhyacian stratigraphic unit and the divergence of Xiaoshan Terrane 1.3.6 Orosirian stratigraphic unit and cratonization 1.4 Tectonic setting of Xiong’er and Xiyanghe groups: application of differentiation index 1.4.1 Preamble 1.4.2 Tectonic models of the Xiong'er and Xiyanghe groups 1.4.3 Linking igneous DI population with tectonic settings 1.4.4 Concluding remarks 1.5 Triassic tectonic setting and Indosinian Orogeny 1.5.1 Sedimentation 1.5.2 Magmatism 1.5.3 Metallogenesis 1.5.4 Concluding remarks 1.6 Yanshanian tectonism and magmatism 1.6.1 Geology and geochemistry of the Yanshanian granitoids 1.6.2 Differences between the mid- and late Yanshanian granitoids 1.6.3 Tectonic implications 1.6.4 Concluding remarks References Chapter 2 Mo mineralization types, in space and time Abstract 2.1 Introduction 2.2 Trichotomy of endogenic processes 2.2.1 Epizonogenism and trichotomy of endogenic processes 2.2.2 Comparison of epizonogenism with other related terms 2.3 Three classes of hydrothermal mineral systems 2.3.1 Trichotomy of hydrothermal mineral systems 2.3.2 Epizonogenic hydrothermal mineral system 2.3.3 Metamorphic-hydrothermal mineral system 2.3.4 Magmatic hydrothermal mineral systems 2.4 Genetic types of Mo deposits in Qinling Orogen 2.5 Mineralization in space and time 2.5.1 Mineralization: spatial relationships 2.5.2 Mineralization: temporal relationships References Chapter 3 Porphyry Mo deposits Abstract 3.1 Introduction 3.1.1 Classification of porphyry Mo deposits 3.1.2 Outline of porphyry Mo deposits in Qinling Orogen 3.2 The Jinduicheng Mo deposit 3.2.1 Introduction 3.2.2 Regional geology 3.2.3 Ore-causative porphyry 3.2.4 Ore geology 3.2.5 Fluid inclusions 3.2.6 Ore deposit geochemistry 3.2.7 Timing of mineralization 3.2.8 Concluding remarks 3.3 The Donggou Mo deposit 3.3.1 Introduction 3.3.2 Local geology 3.3.3 Donggou granite porphyry 3.3.4 Ore geology 3.3.5 Fluid inclusions 3.3.6 Isotope geochemistry 3.3.7 Timing of mineralization 3.3.8 Concluding remarks 3.4 The Yuchiling Mo deposit 3.4.1 Introduction 3.4.2 Regional and deposit geology 3.4.3 Host and ore-causative granitic intrusions 3.4.4 Alteration and mineralization 3.4.5 Fluid inclusion geochemistry 3.4.6 Isotopic geochemistry 3.4.7 Geochronology 3.4.8 Discussion 3.4.9 Concluding remarks 3.5 The Leimengou Mo deposit 3.5.1 Introduction 3.5.2 Regional and deposit geology 3.5.3 The ore-causative porphyry 3.5.4 Ore Geology 3.5.5 Fluid inclusion studies 3.5.6 Isotope studies 3.5.7 Geochronology 3.5.8 Summary and concluding remarks 3.6 The Wenquan Mo deposit 3.6.1 Introduction 3.6.2 Regional and deposit geology 3.6.3 The ore-causative granite 3.6.4 Alteration and mineralization 3.6.5 Fluid inclusions studies 3.6.6 Isotope geochemistry 3.6.7 Timing of mineralization 3.6.8.
