This book is intended for use in an introductory optical mineralogy course. The objective in preparing the book was to present in a single volume of reasonable size both a thorough treatment of optical theory as it pertains to mineral identification with the petrographic microscope, and detailed mineral descriptions of the common rock-forming minerais. The first seven chapters <leal with optical theory and provide an introduction to the properties oflight, a description of the petrographic microscope, and a discussion of the optical properties of isotropic and anisotropic materiais. Detailed step-by-step procedures have been included to guide students through the measurement of optical properties in both thin section and grain mount. Selected spindle stage techniques also are included. <...>

This book is for undergraduates, postgraduates and research workers who wish to gain an insight into present ideas and speculations on the origin of granite batholiths. It is a summary of the proceedings of a one-day meeting of the Geochemistry Group of the Mineralogical Society held at the University of liverpool on the 2nd May 1979, entitled The Origin of Granite Batholiths: Geochemical Evidence. <...>

Petrography (from the Greek petra meaning rock and graphus meaning writing or a record) originated over 150 years ago as a technique employed primarily by geologists, who used microscopes to examine rock samples to identify their mineralogical and chemical characteristics. Petrographic techniques have since been applied to a wide range of materials used in construction including building stone, aggregate, soil, cement, concrete, mortar, brick, and bituminous mixtures. The polarising microscope has been used for the examination of cementitious materials since 1887. Almost one hundred years ago a series of six articles'1' in Concrete and Concrete Construction, the forerunner of today's CONCRETE, described the possibilities of using a microscope for examining concrete. In the last 40 years, petrography has become widely used for both research and commercial investigation of concrete structures. Petrographic examination is a laboratory procedure that is unique in that it relies highly on visual inspection of the samples. It requires specialist sample preparation and microscopical equipment and operators with appropriate qualifications and experience. Using the microscope the petrographer can determine the composition of concrete, assess its quality, and investigate the causes and extent of any deterioration. Photographs taken through the microscope (photomicrographs) record petrographic features of concrete samples. <...>

The initial concept of a photographic atlas on fault rocks was developed  during informal discussions at the Geological Society of America Penrose  Conference "Significance and Petrogenesis of Mylonitic Rocks" held at San  Diego, California, in spring 1981, and coconvened by the editors of this  book. Many participants felt that a new consensus about mylonites and ductile shear zones had been achieved at the conference, based largely upon the  contributions of geoscientists who brought perspectives from the laboratory  as well as from the field. In part motivated by the publication (1982) of the  Atlas of Deformational and Metamorphic Rock Fabrics (and its predecessor,  the Atlas of Rock Cleavage) both edited by G. J. Borradaile, Μ. B. Bayly, and  C. McA. Powell, we felt that a collection of photographs of features characteristic of faults and shear zones, ranging in scale from mesoscopic to microscopic to even submicroscopic, together with carefully documented locations  and regional (or experimental) information, would provide a valuable reference as well as a teaching device <...>

Concrete is an essential and irreplaceable constructional material in the modern world. In  recent times, technological advances in the manufacture of cements and the expansion of  the use of concretes and related materials in civil engineering have led to a need for a practical, science-based understanding of these materials and the relationships between their  compositions and properties.
