The Field Guide to Geology, Updated Edition tells the fascinating story of the Earth in a vivid, engaging fashion. Covering a variety of topics, the book includes information on how matter, stars, and the solar system evolved; how the Earth acquired its shape and surface; the structures of the Earth's crust; the major forms of igneous rock and the processes by which all rocks are created; the relationship between soil and rock erosion and the flow of rivers; and the effect of ice and wind on the Earth's surface
Featuring more than 500 two-color maps, charts, and other illustrations, comprehensive appendixes on geologists and their accomplishments, a worldwide listing of geologic displays, and a bibliography, the gook is a fine introduction for readers to understand the course of the Earth's evolution.
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:
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.
