Mineral deposits have supplied useful or valuable material for human consumption long before they became objects of scientific curiosity or commercial exploitation. 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.

Commentaire
`However, it should serve as an excellent information resource for professional economic geologists, and for others wishing to become acquainted with a particular deposit type, or method of interpretation.'

`The diverse geological settings of metallic ore deposits and the varied methods used in assessing their genesis make writing a comprehensive textbook on ore deposits a formidable challenge. Kula Misra has met that challenge and produced a first-rate book that reviews the techniques employed in ore deposit research and summarize the geological and geochemical characteristics and origins of selected classes of metallic ore deposits. In a field that generates new data daily, Understanding Mineral Deposits is up-to-date useful. With this book he has succeeded in high-lighting the multidimensional nature of economic geology. It is also an excellent reference for professional geologists and a useful txt for senior-or graduate level course in metallic mineral deposits.'
