    Atlas of Igneous Rocks and Their Textures

    PUBLISHER: Wiley ; AUTHORS: W S MacKenzie, C H Donaldson, C Guilford

    Atlas of igneous rocks and their textures A companion volume to the Atlas of Rock-forming Minerals in Thin Section, this full-colour handbook is designed to be used as a laboratory manual both by elementary students of earth sciences undertaking a study of igneous rocks in thin section under the microscope, and by more advanced students and teachers as a reference work. The book is divided into two parts — Part One is devoted to photographs of many of the common textures found in igneous rocks with brief descriptions accompanying each photograph. Part Two illustrates the appearance of examples of some sixty of the commonest (and a few not so common) igneous rock types; each photograph is accompanied by a brief description of the field of view shown. Nearly 300 full-colour photographs are included, and in many cases the same view is shown both in plane-polarized light and under crossed polars. A brief account of how thin sections can be prepared is included as an appendix. It is believed that the amateur geologist using these instructions will be able to make his own thin sections and, with the aid of a relatively simple microscope, enjoy the study of rocks in thin section.

    Igneous Rocks and Processes: A Practical Guide

    Publisher: Wiley-Blackwell ; Writer: Robin Gill

    Posted Image



    This book is for geoscience students taking introductory or intermediate-level courses in igneous petrology, to help develop key skills (and confidence) in identifying igneous minerals, interpreting and allocating appropriate names to unknown rocks presented to them. The book thus serves, uniquely, both as a conventional course text and as a practical laboratory manual.
    Following an introduction reviewing igneous nomenclature, each chapter addresses a specific compositional category of magmatic rocks, covering definition, mineralogy, eruption/ emplacement processes, textures and crystallization processes, geotectonic distribution, geochemistry, and aspects of magma genesis. One chapter is devoted to phase equilibrium experiments and magma evolution; another introduces pyroclastic volcanology. Each chapter concludes with exercises, with the answers being provided at the end of the book.
    Appendices provide a summary of techniques and optical data for microscope mineral identification, an introduction to petrographic calculations, a glossary of petrological terms, and a list of symbols and units. The book is richly illustrated with line drawings, monochrome pictures and colour plates.

    Volcanic Textures: a guide to the interpretation of textures in volcanic rocks

    Authors: J.McPhie, M. Doyle and R. Allen

    Posted Image



    Volcanic Textures provides a practical guide to the description and interpretation of important textures in lavas, syn-volcanic intrusions and a wide variety of volcaniclastic deposits. Many examples come from the Cambrian Mount Read Volcanics, the submarine volcanic host sequence to several world-class polymetallic massive sulfide ore deposits in western Tasmania. These are compared with younger analogues and contrasting subaerial sequences in the USA, Japan, New Zealand, Italy, Central America and South America.

    The book contains 46 thematic plates comprising 330 colour photographs, each accompanied by a description and, where appropriate, an interpretation. The plates are complemented by text that reviews relevant genetic processes and facies relationships. Part 1 gives an introduction to terminology, field identification techniques and classification. Part 2 describes selected textures, components and structures in volcanic deposits. Part 3 focuses on lavas, shallow intrusions and related autoclastic deposits. Part 4 covers pyroclastic and other volcaniclastic deposits with emphasis on transport and depositional processes. Part 5 outlines the textual effects of hydrothermal alteration, especially in the vicinity of massive sulfide ore deposits, using examples from the Mount Read Volcanics.

    Volcanic Textures is designed for use by exploration geologists, graduate students and other earth scientists with an interest in physical volcanology, especially those engaged in mapping and interpreting volcanic sequences.

    DK-Experience-Volcano

    Author: Anne Rooney ; Publisher: Dorling Kindersley

    Posted Image


    A completely unique approach to illustrated reference, DK s new Experience series uses panoramic storyboard sequences to help readers dive into the printed page and learn in a whole new way as the action unfolds.

    Most of the world��s volcanoes can be found on the Ring of Fire, a fringe of volcanoes erupting around the edge of the Pacific Ocean.
    Wherever the Pacific plate meets continental plates or other, younger oceanic plates, subduction feeds volcanoes. Some form arcs of volcanic islands, such as Japan. Others are in mountain ranges formed where the Pacific plate collides with a continent, such as the high peaks of the Andes on the west coast of South America.
