With more than 400 quality color images and photographs this book, published by the Colorado Geological Survey, is a celebration of the world-class geology found in the state.
The book is aimed at the general public, but will also be of interest to professional earth scientists and students. The book not only displays Colorado’s fantastic geologic features, but also serves as a primer on geologic principles and concepts. The book discusses and illustrates three broad categories: Colorado’s rocks and structures, Colorado’s Geologic History, and the impact of Colorado’s Geology on humans which includes water, economic resources, and geologic hazards.
Dr. Vince Matthews, senior editor for the publication, stated, “This heavily illustrated book exposes the breadth and depth of Colorado’s rich geologic resources. I knew that Colorado’s geology was special. But, researching this book made me aware of many new and exciting facets of the state’s well-displayed, diverse geology. We were fortunate to have so many talented people contribute their knowledge, photographs, and time to making this a publication that all can enjoy and learn from.”
The Deluxe Moh's Hardness Pick Set now comes in two case types. The wooden case is small enough to carry and the top screws into the base to make a perfect desk stand. The plastic case is longer but the thinner size makes it easier to carry in your field tool set.Hardness is an important and quantifiable physical characteristic of a mineral and in your effort to identify an unknown mineral, the hardness, if known, combined with other properties, can narrow your search to just a handful of possibilities. Simply scratch a smooth surface of your unknown mineral with the picks of various indicated hardness. As an example, if a No. 5 pick scratches the mineral, but a No. 4 pick does not, then your mineral hardness is 4.5. Then compare this against a table of minerals listing hardness values to aid in identifying the unknown mineral.
