Derived from the world-renowned McGraw-Hill Dictionary of Scientific and
Technical Terms, Sixth Edition, this vital reference offers a wealth
of essential information in a portable, convenient, quick-find format. Whether
you're a professional, a student, a writer, or a general reader with an interest
in science, there is no better or more authoritative way to stay up-to-speed
with the current language of geology and mineralogy or gain an understanding
of its key ideas and concepts.
Written in clear, simple language understandable to the general reader, yet
in-depth enough for scientists, educators, and advanced students, The McGraw-Hill
Dictionary of Geology & Mineralogy, Second Edition:
Here are minerals from the United States, including mines in New Jersey, New York, Arizona, and California as well as beautiful and unusual minerals from Canada, Mexico, Greenland, Italy, Sweden, and other places. Included are values, a comprehensive resources section, plus helpful advice on caring for, collecting, and displaying minerals. The field of collecting fluorescent minerals is relatively new and this is one of the most complete references available.
The Mineral Hardness Ruler is a stimulating visual aid, educates in one phase of mineralogy, and provides the standard ruler measurement scales needed in classes.
Rockhounds, mineral enthusiasts, students, teachers, geologists, and any one interested in rocks and minerals will find the Mineral Hardness Ruler a handy visual aid for quick information on mineral hardness.
The two-sided, flexible, glossy, vinyl ruler consists of five scales: three measurement scales and two mineral hardness scales. The measurement scales are in standard ruler measurements of tenths of inches, sixteenths of inches, and millimeters. Mohs' relative hardness numbers are integrated into the inch scales, while a separate scale exists for an absolute mineral hardness scale by Rosiwal.
On one side of the ruler are pictures of the ten common minerals, in full color, selected by Mohs for his relative hardness scale. On the reverse side of the ruler are six common items with their relative hardnesses. These items, along with known minerals, can be used as a handy field kit to test the relative hardness of an unknown mineral.
Hardness is one property of a mineral that can be used to distinguish among similar minerals. A given mineral can scratch any other mineral of the same or softer hardness. Over a hundred years ago, the German mineralogist Frederick Mohs devised the relative hardness scale that has found favor with mineralogists for over a century. Others, such as Rosiwal, formed absolute hardness scales using the same minerals as Mohs. For example, diamond, the hardest substance in Nature is not twice as hard as apatite, 10 versus 5, but over twenty thousand times as hard, 140,000 versus 6.5.
Field Geology was designed to serve as a field reference to aid in recognizing, interpreting, and describing geologic features at the outcrop. Emphasis is on the study of mesocopic features that can be viewed at outcrop scale rather than large structures or landscapes. This book is not an exhaustive or comprehensive treatise on the subject of field geology, but instead cover the information necessary to understand and describe most outcrops...
Field Geology should be useful as a complementary text for any field-related geoscience course such as physical geology, field geology, petrology, and structural geology. The detailed descriptions, illustrations and photographs of geologic features in their field setting will be particularly useful (AG: on a field trip, vacation, or) where field trips are not feasible.
This book is also intended for anyone who needs a good basic review of field geology including graduate students preparing for field mapping, professional geologists who wish to bring their skill up to date quickly and easily and even serious amateur geologists (AG: We believe this is useful to anyone interested in geology in the field!)Self study will be particularly rewarding because an interpretative sketch and detailed description is included with each photograph.
Minerals of the World is an attractive and up-to-date guide to more than 500 minerals from around the world. The succinct text--covering crystallography, properties, names and varieties, structure, diagnostic features, and occurrence--and the discussion of less common minerals not found in other guides make this an invaluable resource. With over 600 exquisite color photographs and crystallographic diagrams, this book is unequalled. It is set to become the field guide of choice for mineral collectors and students of mineralogy.
