Washington Rocks

Active volcanoes, like Rainier and Baker, dominate Washington�s western half, and Columbia flood basalt covers much of the eastern half, but scattered here and there are other equally amazing rocks and features that make the Evergreen State one of the most geologically interesting places in the entire country. With this book as your guide, you can find limestone caves, billion-year-old gneiss, glacial moraines, petrified forests, fossilized palm leaves, upside-down sandstone beds, and ancient landslides. Or you can explore the mind-boggling canyons, waterfalls, and scabland carved by the torrential Missoula Floods, check out the glacially carved granite of the North Cascades, or watch sea stacks erode in the pounding surf of the Pacific Ocean. Washington Rocks! is part of the state-by-state Geology Rocks! series that introduces readers to some of the most compelling and accessible geologic sites in each state. The 57 sites in this book are scattered throughout the state, from Steptoe Butte in the southeast, the namesake of the steptoe geologic feature, to trilobite-bearing limestone in Box Canyon in the northeast, and from glacial gouges on Iceberg Point in the San Juan Islands to ghost forests in Willapa Bay, trees killed during the last great earthquake. Colorful photographs and instructive diagrams make this book a must-have for rockhounds, students, tourists, and residents alike.

Report which combines results obtained by U.S. Geological Survey parties with information derived from study of specimens of tin ores and associated minerals from York region of Seward Peninsula, Alaska. Presents information about occurrences and value of tin of interest to prospectors.

Decades of field and microscope studies, and more recent quantitative geochemical analyses have resulted in a vast, and sometimes overwhelming, array of nomenclature and terminology associated with igneous rocks. This book presents a complete classification of igneous rocks based on all the recommendations of the International Union of Geological Sciences (IUGS) Subcommission on the Systematics of Igneous Rocks. The glossary of igneous terms has been fully updated since the first edition and now includes 1637 entries, of which 316 are recommended by the Subcommission. Incorporating a comprehensive bibliography of source references for all the terms included in the glossary, this book is an indispensable reference guide for all geologists studying igneous rocks, either in the field or the laboratory. It presents a standardised and widely accepted naming scheme that will allow geologists to interpret terminology in the primary literature and provide formal names for rock samples based on petrographic analyses. It is also supported by a website with downloadable code for chemical classifications.

The origin of different kinds of igneous rocks can be understood in terms of their tectonic setting, and by way of the isotope compositions of strontium, neodymium, and lead. This book explains the petrogenesis of igneous rocks as a consequence of tectonic processes resulting from interactions between asthenopheric plumes and the overlying lithospheric mantle. The relevant principles of isotope geochemistry are explained in the first chapter, making it accessible for university students as well as professionals. The relevant isotopic data is presented in diagrammatic form. The book contains more than 400 original drawings.

Through the sage advice of one of the world's foremost female climbers and the lens of an internationally acclaimed photographer, women learn that climbing is more fun than dangerous, that overcoming fear can boost self-esteem, and that the fitness benefits for women are tremendous. Most women learn climbing from men, but the sport is different fora woman, both physically and psychologically—and it is empowering for women to learn about climbing from “girls” who've been on the rocks themselves. The numerous photos in this full-color guide do wonders to clearly explain the various techniques, equipment, and styles of climbing for women. Further bringing the sport to life, author Katie Brown presents her interviews with numerous female climbers—from a young girl to a sixty-something professional climber—to learn what the sport has done for them.
