Download or read book Transmitted Light Microscopy of Rock Forming Minerals written by Susanne Theodora Schmidt and published by Springer Nature. This book was released on 2023-06-09 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a guide of optical mineralogy for beginners and microscopists who need to brush up their knowledge. It allows the fast identification of common rock-forming minerals in a thin section using a polarized light microscope and transmitted plane and cross polarized light. The book summarizes essential principles of optical mineralogy in numerous schemes. It explains, with the aid of more than 1000 microscopic images, how to determine the diagnostic optical characteristics of a mineral in a thin section. Seventy-two mineral plates of sixty-five common rock-forming minerals comprising typical microscopic images in plane and cross polarized light illustrate the most important optical and crystallographic parameters and their diagnostic characteristics and typical appearance in various geological settings. The original approach of the book is to facilitate mineral identification by mineral plates organized according to color in transmitted plane polarized light and, in each color category, according to decreasing maximum birefringence in cross polarized light. In addition, two chapters are devoted to the classification of magmatic and metamorphic rocks and their common mineral parageneses and textures. The book reflects the author’s experience of teaching optical mineralogy in the most efficient way possible to generations of students at the Universities of Heidelberg (Germany), Basel (Switzerland), and Geneva (Switzerland).

INTRODUCTION - To Optical Mineralogy and Petrography The Practical Methods of Identifying Minerals in Thin Section With the Microscope and The Principles Involved in The Classification of Rocks - PREFACE: IN THE preparation of this volume the writer has attempted to gather together and systematize in a manner accessible for ready reference those facts which are essential to a field geologist or to a mining engineer in an understanding of the fundamental principles involved in the classification and identification of rocks. In the field, a preliminary classification is usually made by macroscopic means. However, it is often necessary to make a more careful classification by a microscopic examination of a thin section of the minerals comprising the rock mass. To do this successfully requires a knowledge of the application of light to crystalline substances. This volume differs from most of the reference and text books relating to this subject in that it incorporates in one volume the elements of optical mineralogy and the elements of petrography. In Part One, eight general operations for the determination of unknown minerals in thin section are described, prefaced by a short summary of the principles of optics which apply to the transmission of polarized light through minerals. Descriptions of fiftyeight of the most common of the rock-making minerals are given, special attention being given to the criteria for the determination of these minerals in thin section. Their form, cleavage, twinning, color, refringence, bi refringence, extinction angles, pleochroism, absorption, optical character, inclusions, alterations, occurrences, uses, and differentiation from similar minerals, are all discussed whenever applicable. An elementary knowledge of crystallography and descriptive mineralogy is assumed. In Part Two, the principles of petrography are discussed briefly. Attention is given to the classification and description of the more important igneous rock types. Following Iddings, Winchell, and other American petrographers, the symbols X, Y, and Z, are here employed in referring to the axes of ether elasticity, instead of the German a, b, and c, used in many text and reference books. This is done to avoid confusion, especially in conversation or discussion, with the crystallographic axes. 2 The writer is indebted to Professor Frank R. Van Horn for suggestions. Among the reference and text books most frequently consulted the writer wishes to acknowledge Winchells Elements of Optical Mineralogy, Johannsens Manual of Petrographic Methods, Luquers Minerals in Rock Sections, Rogerss Study of Minerals, Findlays Igneous Rocks, Kemps Handbook of Rocks, Ries and Watsons Engineering Geology, and Farrells Practical Field Geology.

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.

Book excerpt: Excerpt from A Key for the Determination of Rock-Forming Minerals in Thin Sections Tables for the determination of minerals have heretofore been made of secondary importance in text books. In this volume the reverse method has been adopted and the de scriptive tables make up the greater portion of the book. Theoretical discussions in optics have been avoided so far as possible, and only enough has been given to make clear that which is necessary for the practical determination of the minerals. The material has been condensed as much as is consistent with clearness, and all of the descriptions are given in as concise a form as possible. Owing to the difficulty of having the pages of the index indented by machinery, it was found necessary to extend the leaves to the full width of the book, and to indicate the lines along which the student should cut the pages. After trim ming along the lines shown, it will be found convenient to form another index guide by cutting off about one-half inch from the upper right hand corners of the pages descriptive of negative minerals.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Tables for the Determination of the Rock-Forming Minerals: With a Chapter on the Petrological Microscope There is probably no branch of geology in which an unaided student has more difficulty in making a start than in the microscopic study of rocks. This is especially to be regretted, as it is now recognised that this method of research is indispensable for any accurate work on the igneous rocks. Many a resident on the great volcanic plateaux of India, Africa, or America, or on the vast tracts of gneiss and schists which form such a large proportion of the earth's crust, is debarred from geological work by the difficulty of identifying minerals under the microscope. Thus our knowledge of many of these areas is very deficient, for they are only known by occasional rapid traverses; and the problems they present are so complex that they can only be fully worked out by a resident or by a thorough survey. Elementary students feel the difficulty, though they have the advantage of personal instruction. Probably every one who has tried elementary teaching in geology has felt the need of some simple book of reference. The elaborate tables of Rosenbusch and Michel Levy and Lacroix are, of course, perfect in their way, but they are really summaries of the characters of the minerals rather than guides to their rapid determination. With these, if one knows the name of a mineral, its characters can be at once ascertained; but what the student usually requires is the reverse process. He can recognise the characters of a mineral by the microscope, and from these he wants to know its name. The previous tables afford little assistance in doing this. Professor L winson-Lessing has now supplied this want by a set of tables arranged on what may be called the "dichotomous method."

Download or read book The Preparation of Thin Sections of Rocks Minerals and Ceramics written by D. W. Humphries and published by Oxford University Press, USA. This book was released on 1992 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The microscope is a familiar tool in the biological and medical sciences, and its application to the study of plant and animal tissues is well known. That it can be applied to the study of rocks, minerals, and ceramics may come as a surprise to many people, including experienced microscopists. The principle requirement is that a section or slice, thin enough to be transparent to transmitted light, can be prepared. This is a practical guide to the preparation of thin sections. All that is needed are some simple equipment, a modicum of manual dexterity, and a measure of patience. Above all, thin sections can be made without expensive machinery, although a brief account of mechanical aids is included here. Methods of making polished sections for reflected light microscopy, staining sections, making peels, and extracting heavy mineral suites from sands are covered in later chapters. The book will appreciated as a handy laboratory guide by geologists, earth scientists, materials scientists, ceramicists, and microscopists.
