Like the terrain it covers, Annals of the Former World tells a many-layered tale, and the reader may choose one of many paths through it, guided by twenty-five new maps and the "Narrative Table of Contents" (an essay outlining the history and structure of the project). Read sequentially, the book is an organic succession of set pieces, flashbacks, biographical sketches, and histories of the human and lithic kind; approached systematically, it can be a North American geology primer, an exploration of plate tectonics, or a study of geologic time and the development of the time scale. As clearly and succinctly written as it is profoundly informed, this is our finest popular survey of geology, and a masterpiece of modern nonfiction writing.
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.
The BelOMO 10x21mm(.85") triplet loupe magnifier has a viewing area of 0.65 inch (17mm), much larger than the Bausch & Lomb Hastings Triplet Magnifier. The 3 elements making up this achromatic triplet provide a bright and clear view. The 10x power magnification provides the best magnification to depth of field ratio and is the most popular power for a hand held magnifier. The housing and cover are machined metal and coated with a matte black finish and assembled using flathead screws. Belorussian Optical and Mechanical Association (BelOMA), makers of sights for guided weaponry, camera lenses, and other optical components manufacturers these loupes.
We highly recommend this loupe. This is the lens we use all the time.
Each BelOMO loupe we ship is custom treated to prevent the screws from coming loose with usage.
The Estwing Supreme 22 oz Pointed Tip Rock Hammer (E3-22P) is the standard, the rock pick carried by more geologist and rockhounds. Light enough to easily carry but heavy enough to crack some rock. Estwing Supreme quality in a one-piece forged pointed tip rock pick. Fully polished solid steel with the Estwing shock absorbing nylon-vinyl grip which has been tested to reduce shock by 50%.
|Head Width||7 inches|
|Overall Length||12 3/4 inches|

|Total Weight||2 pounds|
Estwing has introduced a new line of tools called Big Face. The Big Face tools have, wait for it, a big head. The head is widen at the end to make is safer and more effective when using the hammer for driving chisels. The extra 2 ounces on the Estwing Supreme Big Face 24 oz Pointed Tip Rock Hammer E6-24PC makes it a better hammer for smashing rocks or driving those chisels.
