Introduction
This book is
created as a field manual for geologists who work in the mining exploration
industry. It is also envisaged that it would be used as a book and reference
for students in university and college Applied Geology courses. The goal of the
book is to lay out some of the practical abilities that a graduate geologist
needs to become an explorationist. It is not meant to be a textbook on geology
or ore deposit theory, but rather a practical "how-to" guide. An
explorationist is a professional, usually, a geologist, who conducts scientific
and organized searches for ore deposits. Technical assistants, tenement
managers, environmental and safety personnel, drillers, surveyors, IT
specialists, geophysicists and geochemists, ore reserve specialists, and
various types of consultants are among the mineral exploration professionals.
Exploration geologists are typically jacks-of-all-trades who have a broad view
of the team and the project
Even though explorationist is an uncomfortable and unnatural term, it is the only word available to capture the entire set of skills required to identify and classify commercial mineralization. Even the mine geologist is an explorer, aiming to delineate ore blocks ahead of the mining crews. The collecting, recording, and presentation of geological knowledge so that it can be used to predict the presence of ore are the most essential and cost-effective abilities of the explorationist, and these are the skills that this book focuses on. Practical field practices taught at the undergraduate level are frequently lost and, in some cases, are not reinforced by subsequent practice; some abilities that an explorationist requires may never be fully taught in a university setting. Identifying potential ground for acquisition, comprehensive prospect mapping, or logging drill core or cuttings, for example, are rarely included in basic training courses even though no book can replace hands-on experience and demonstration, this handbook strives to overcome some of these shortcomings.
The book does not provide a set of universal laws that must be followed at all times. It describes fundamental skills and approaches that have shown to be useful in the hands of numerous geologists. The author does not want to be prescriptive; each geologist must create their own techniques and will ultimately be assessed on the results, not the process by which they were obtained. The only "correct" method to accomplish anything in mineral exploration is the way that locates ore the quickest and most cost-effectively. However, an individual should build their own style of operation after having tested and learned about those processes that have proven to function effectively in the field and are widely regarded as good exploration practices. New ideas and techniques emerge regularly, therefore no book like this can be considered definitive. Geologists should utilize this document critically to maintain it up to date and relevant.
The book's chapters roughly correspond to the steps that a typical exploration program would take. The generation of new projects and prospects and the nature of the exploration process are discussed in Chap. 1. The approaches for creating geological maps from remote sensing reflectance imaging, surface outcrop, and mine openings are described in Chaps 2 and 3. Trenching, pitting, stripping, and subsurface development are all techniques used by explorations to produce fresh rock exposure in Chapter 4. All components of drilling are covered in Chapters 5, 6, and 7 (along with various appendices). These chapters make up a significant portion of the book, demonstrating the relevance of drilling to the explorationist. A full discussion of the remote sensing images provided by Land observation satellites – a modern-day gift to explorers – may be found in Chap. 8. Although this book is mostly about geological procedures, Chap. 9 provides a quick summary of the more often utilized exploration geophysics and geochemical techniques. Finally, Chap. 10 examines digital exploration databases and describes how to store, manipulate, and show digital exploration and mining data using geographic information systems (GIS) and exploration software.
This second edition has been considerably expanded from the first version published in 1997 to reflect advances in exploration tactics over the last ten years. Basic geological field procedures remain an essential skill for explorations, and they are the focus of a large portion of the book. New technical advancements, on the other hand, have broadened her toolkit. Faster and more reliable technologies for orienting core in diamond drilling have made this procedure nearly commonplace, resulting in a greater awareness of the usefulness of quantitative structural recording. As satellite navigation systems have improved, the role of GPS in providing survey controls for comprehensive geological mapping and the collecting of geochemical and geophysical data has grown significantly. Commercial land observation satellites with very high resolution are progressively offering imagery that rivals the finest of air photography in terms of quality and cost.
Traditional geophysical and geochemical techniques have been revolutionized thanks to an almost exponential increase in processing power, memory capacity, and graphics ability in today's desktop and laptop computers, which, when combined with new powerful software packages and sophisticated instrumentation, has revolutionized traditional geophysical and geochemical techniques. Today's software programmers enable massive volumes of data to be processed and evaluated, leading to a trend among today's explorers to spend more time in front of a monitor than in the field. Digital data that has been processed and presented as multi-color 3-D surfaces can take on a life of its own, apart from the truth it is meant to portray. There is a growing risk that the explorationist will lose sight of the importance of excellent data collecting by focusing on data handling.
Much of this book's underlying theory is that, for geological data to be useful in locating ore deposits, ideas and insights must be applied in an organized manner to manage all stages of data management, from field collecting to final presentation. It's worth remembering the well-known remark in these days of computerized data storage and processing.
The book explains how to acquire knowledge using geological approaches. The reader is in charge of the rest.
