Field Geology Illustrated, 2n Edition 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 Illustrated 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.
Enjoy the map of 1910 issued by the State Mining Bureau featuring the many mineral deposits of Southern California. This map is divided into four easy to read sections.
The details of Inyo County are outstanding as shown on the map of 1883. The interesting text accompanying this map has been included.
The gemstone site locations have been compiled from many sources and detailed on a modern USGS planometric map. Many sites are may be found east of Owens Lake. The desert area of Southeastern California should be a rockhounds delight.
Map identifies locations of: gold and silver, actinolite, agate, amethyst, andesite, apatite, autunite, aragonite, azurite, anglesite, barite, beryl, bornite, bloodstone, calcite, chalcopyrite, chalcedony, chert, chrysocolla, dumortierite, epidote, feldspar, flourite, fossils, garnet, geodes, hematite, ilmenite, kyanite, jade, jadeite, jasper, limonite, magnetite, malachite, obsidian, olivine, onyx, opal, opalite, petrified palm, petrified wood, psilomelane, quartz, realgar, rhodochrosite, rhodonite, rhyolite, siderite, scheelite, schist, serpentine, stibnite, sphalerite, sphalerite, wollastone, wulfenite, travertine, tourmaline, and turquoise.
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.
