Te learning process has been slow and is still incomplete. Te bemusement began directly upon leaving the academic confnes, which in retrospect lef one keen young geologist very ill-equipped to interpret the mineralising process via feld or hand lens style observation of the rocks. Enlightenment has proceeded via a series of events:- 1. Te slow process of feld observation as an industry-based mine and exploration geologist. 2. Te opportunity to visit numerous diferent styles of ore deposit both as an academic and consultant. 3. Te need to answer questions from several generations of enquiring students. 4. Te privilege of being able to conduct research. 5. Te good fortune to be associated with a few top class economic geologists who actually knew what they were doing! Professor Willard C. Lacy deserves the most credit for quietly demonstrating the value of frst principles concerning fuid channelways, combined with an ability to look properly at the t- tures. Despite rapid technological advances this skill remains fundamental both to the practi- ing exploration geologist and to the academic researcher who is interested in understanding ore forming processes. Te fve volumes comprising this presentation were originally compiled individually over a period of eleven years, and aimed to progressively guide the observer though the principles of recogn-i tion concerning infll, alteration, overprinting, and fnally to ore-related breccias.

DOWNLOAD EBOOK →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.

In fact, the earliest human interest in rocks was probably because of the easily accessible, useful (e. g. , red pigment in the form of earthy hematite) or valuable (e. g. , native gold and gemstones) materials they contained at places. In modem times, the study of mineral deposits has evolved into an applied science employing detailed field observations, sophisticated laboratory techniques for additional information, and computer modeling to build complex hypotheses. Understanding concepts that would someday help geologists to find new mineral deposits or exploit the known ones more efficiently have always been, and will continue to be, at the core of any course on mineral deposits, but it is a fascinating subject in its own right, even for students who do not intend to be professional economic geologists. I believe that a course on mineral deposits should be designed as a "capstone course" that illustrates a comprehensive application of concepts from many other disciplines in geology (mineralogy, stratigraphy and sedimentation, structure and tectonics, petrology, geochemistry, paleontology, geomorphology, etc. ). This book is intended as a text for such an introductory course in economic geology, primarily for senior undergraduate and graduate students in colleges and universities. It should also serve as a useful information resource for professional economic geologists.
