Excerpt from Outlines of Mineralogy, Geology, and Mineral Analysis, Vol. 1 of 2 Mohs has arranged all minerals in what he calls a natural history order. The object of his arrangement is to enable a beginner to discover the name of any mineral contained in the system by its characters, precisely in the same way as in botany or entomology, any plant, or insect, contained in the system may be discovered by attending to its characters. And M. Mohs considers it as a vast advantage to mineralogy to be thus freed from the trammels of Chemistry, by which it has been hitherto hampered.

Excerpt from Outlines of Mineralogy, Geology, and Mineral Analysis, Vol. 2 of 2 It is evident, that whatever causes gave this oblate figure to the globe, have acted upon the solid as well as the fluid parts. The land, in a general point of view, is as much elevated at the equator as towards the poles. But, since the equatorial regions are 12 miles farther from the centre than the parts at the pole, it is obvious, that if the solid nucleus of the globe were a true sphere, the sea would be accumulated by the centrifugal force in the equatorial regions, which would have been completely submerged while the polar regions would have been left dry and elevated many miles above the level of the waters. The ocean would have formed a broad and deep zone round the equator, separating the two continents encircling the poles.

In this book Rockhound: A Geography of Collecting you will be shown Ontario's incredible history of mineral extraction and as you will see, rockhounds follow in the signature that every industry left. The full Rockhound series tells you how and where to find crystals, minerals, gold, diamonds and all manner of rock and mineral treasure. for the collector this book is an absolute gem and an essential guide to Ontario geology as it relates to mineral collecting.

Introduction to Mineralogy and Petrology, second edition, presents the essentials of both disciplines through an approach accessible to industry professionals, academic researchers, and students alike. This new edition emphasizes the relationship between rocks and minerals, right from the structures created during rock formation through the economics of mineral deposits. While petrology is classified on the lines of geological evolution and rock formation, mineralogy speaks to the physical and chemical properties, uses, and global occurrences for each mineral, emphasizing the need for the growth of human development. The primary goal is for the reader to identify minerals in all respects, including host-rocks, and mineral deposits, with additional knowledge of mineral-exploration, resource, extraction, process, and ultimate use. To help provide a comprehensive analysis across ethical and socio-economic dimensions, a separate chapter describes the hazards associated with minerals, rocks, and mineral industries, and the consequences to humanity along with remedies and case studies. New to the second edition: includes coverage of minerals and petrology in extra-terrestrial environments as well as case studies on the hazards of the mining industry. Addresses the full scope of core concepts of mineralogy and petrology, including crystal structure, formation and grouping of minerals and soils, definition, origin, structure and classification of igneous, sedimentary and metamorphic rocks Features more than 250 figures, illustrations and color photographs to vividly explore the fundamental principles of mineralogy and petrology Offers a holistic approach to both subjects, beginning with the formation of geologic structures that is followed by the hosting of mineral deposits and the exploration and extraction of lucrative, usable products that improve the health of global economies Includes new content on minerals and petrology in extraterrestrial environments and case studies on hazards in the mining industry
