Available in PDF, EPUB and Kindle. Book excerpt: The present study has been directed towards investigating quantitative measurements of colours in minerals, which might serve as a readily accessible means of identification and understanding related properties. A review of the concepts of colour measurement is described in the first part of the thesis. Attention has been paid to the improvement and application of methods of colour measurement,- in mineralogy and gemmology. Computational procedures and all the necessary computer programmes for calculating colour values are given with examples. For this purpose appropriate measurements of spectral reflectivity for opaque minerals, and spectral transmittance for non-opaque minerals and facetted gemstones are described. Quantitative measurements of other colour properties - colour constancy, bireflectance and reflection pleochroism - are described and defined. A study of some colour problems in ore minerals is made. Tables of colour values and spectral reflectivity data for 130 ore minerals are given, and these values are also presented in colour diagrams. The uses of quantitative colour values and colour diagrams are explained with examples.

Available in PDF, EPUB and Kindle. Book excerpt: This book is the successor to A practical introduction to optical mineralogy, which was written in the early 1980s, and published by George Allen & Unwin in 1985. Our intention, once again, is to introduce the student of geology to the microscopic examination of minerals, by both transmitted and reflected light. These techniques should be mastered by students early in their careers, and this text has been proposed in the full awareness that it will be used as a laboratory handbook, serving as a quick reference to the properties of minerals. However, care has been taken to present a systematic explanation of the use of the microscope, as well as to include an extended explanation of the theoretical aspects of optical crystallography in transmitted light. The book is therefore intended as a serious text that introduces the study of minerals under the microscope to the intending honours student of geology, as well as providing information for the novice or interested layman.

Book excerpt: Provides an up-to-date introduction to the subject of ore microscopy, emphasizing the basic skills required for the study of opaque minerals in polished sections. Describes the modern ore microscope, the preparation of polished and polished-thin sections of opaque minerals and ores, and the identification of these minerals using both qualitative techniques and the quantitative methods of reflectance and microhardness measurement. Later sections discuss the interpretation of textural intergrowths of ore minerals and the determination of their paragenesis, along with the examination of coexisting minerals for determining their physio-chemical conditions of formation. Appendices contain the data necessary to identify approximately 100 of the more common ore minerals and those frequently encountered by the professional scientist.

Book excerpt: Colour is the most obvious property that the ore microscopist uses in the identification of opaque minerals. This book sets out to answer the question: Why do particular opaque minerals have colours we see? This includes not only the colour seen in plane polarized light, but also the colours of anisotropic minerals viewed between crossed or slightly uncrossed polars. Beginning with an explanation of the physiological aspects of colour perception and the CIE (Commission Internationale de L'Eclairage) numerical colour specification, the text goes on to examine in detail the physics of the interaction of light with minerals and how the optical properties of sections can be explained in terms of the dispersion of the relative permittivity tensor.

Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Ore Microscopy is a brief introduction to the science of Ore Minerals. It is designed to help undergraduate and postgraduate students of Geology and Earth Science for their practical course. The book gives a comprehensive, handy and scientific description of ores which form a part of Ore Geology and Economic Geology. Illustrated with a wealth of full-colour and black-and-white polished section photographs, the book explains how to observe ores under the microscope in the reflected light. Besides dealing with the texture, structures, and paragenesis of ore minerals, it also deals with the methodology to study physical and optical characters of important ore minerals, such as Sulphides, Arsenides, Antimonides, Molybdenites, Tungstate, and Oxides ores. A brief description mineral paragenesis, paragenetic diagrams, and some important ore-deposits of India and other parts of the world are also given. The book will also prove to be useful for those working in the mineral industry.

Available in PDF, EPUB and Kindle. Book excerpt: Measurements of the optical properties of opaque minerals using a reflected-light polarizing microscope are difficult because they require demanding and exacting techniques. Unlike transparent minerals, which can be easily identified by tests using a transmitted-light petrographic microscope, opaque minerals have few optical properties that can lead to unambiguous identification. The principal properties used to identify opaque minerals are colour and colour intensity. The tables given here are designed to serve as a rapid and efficient way of identifying the common opaque minerals.

Download or read book A Practical Introduction to Optical Mineralogy written by Colin Gribble and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microscopy is a servant of all the sciences, and the microscopic examina tion of minerals is an important technique which should be mastered by all students of geology early in their careers. Advanced modern text books on both optics and mineralogy are available, and our intention is not that this new textbook should replace these but that it should serve as an introductory text or a first stepping-stone to the study of optical mineralogy. The present text has been written with full awareness that it will probably be used as a laboratory handbook, serving as a quick reference to the properties of minerals, but nevertheless care has been taken to present a systematic explanation of the use of the microscope as well as theoretical aspects of optical mineralogy. The book is therefore suitable for the novice either studying as an individual or participating in classwork. Both transmitted-light microscopy and reflected-light microscopy are dealt with, the former involving examination of transparent minerals in thin section and the latter involving examination of opaque minerals in polished section. Reflected-light microscopy is increasing in importance in undergraduate courses on ore mineralisation, but the main reason for combining the two aspects of microscopy is that it is no longer acceptable to neglect opaque minerals in the systematic petrographic study of rocks. Dual purpose microscopes incorporating transmitted- and reflected-light modes are readily available, and these are ideal for the study of polished thin sections.

Book excerpt: Covering theory and practice, this wide-ranging introductory textbook covers the main optical properties of rock-forming minerals that can be recognized under the polarizing microscope. The authors elucidate the basic elements of microscopy, the theory of light transmission through translucent minerals, and the properties of light reflected from opaque minerals. They discuss properties of the main silicate and non-silicate minerals, both translucent and opaque and how the optical properties may be used to identify a mineral. The book features many diagrams, summary tables, and four pages of color illustrations, making it an ideal textbook as well as an authoritative reference.

Download or read book Quantitative Textural Measurements in Igneous and Metamorphic Petrology written by Michael Denis Higgins and published by Cambridge University Press. This book was released on 2006-08-03 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Processes involved in the development of igneous and metamorphic rocks involve some combination of crystal growth, solution, movement and deformation, which is expressed as changes in texture (microstructure). Advances in the quantification of aspects of crystalline rock textures, such as crystal size, shape, orientation and position, have opened fresh avenues of research that extend and complement the more dominant chemical and isotopic studies. This book discusses the aspects of petrological theory necessary to understand the development of crystalline rock texture. It develops the methodological basis of quantitative textural measurements and shows how much can be achieved with limited resources. Typical applications to petrological problems are discussed for each type of measurement. This book will be of great interest to all researchers and graduate students in petrology.
