Great book - it was particularly interesting because I just read John McPhee's Assembling California, which has much of the same information presented in entirely different ways. The various sections of the SF Bay Area (or Region, as it should properly be called in a geological context) are discussed, with their various characteristic rocks and what the faults and geologic action have done to the rocks. The same sets of rocks appear everywhere, from North Bay to South, in the Central Valley and on the peninsula - but in differing amounts, structures, and relationships. The bits where a unique formation shows up in two widely separated areas on either side of a fault are fascinating - illustrating just how far the Pacific Plate has slid up along the side of the North American Plate (hundreds of miles, definitely, possibly more over time). The book inspires me to go want to take a look at various areas, now that I understand something of their structures, too. I saw the red soil just east of the Caldecott Tunnel, for instance - and now I know that's where lava flowed (centuries ago) and baked the soil, turning it red. Absolutely fascinating - I got this from the library, and I think I'd like to own it and take it with me around the Bay Area. ( ) A very satisfying introduction to the geology of the Bay Area. It includes a good introduction to basic geology, which I certainly needed. The book looks and feels like a field guide and I actually went on several trips that were suggested by the book. A plethora of pictures helps in the learning process. At times, it's a bit too heavy on the individual types of rocks at any given geographic location. I would have liked to have that balanced with a good description of why the particular areas look as they do. However, that being said, the book gives a strong general overview of the larger geologic processes that shaped the Bay Area. I know I'll never again look at a rock in the Bay Area the same way. nessuna recensione | aggiungi una recensione

Why does a bit of ocean floor lie on top of Mt. Diablo? Why is Red Rock, that small, knobby island in San Francisco Bay, red? Why is Loma Prieta high? This book is for San Francisco Bay Area residents and visitors who want to explore the geologic world of this spectacular area, to learn about its shapes, colors, and rocky foundations. Doris Sloan illuminates the colorful geologic mosaic that surrounds San Francisco Bay and lucidly explains the complex and fascinating processes that have forged it over millions of years. In a lively and engaging style, Sloan describes forces such as the movement of tectonic plates, erosion, the waves on the coast, and human activity. She provides background information on the processes, time frame, and rocks that are the key to understanding the Bay Area landscape and geologic history, then turns to distinct regions of the Bay Area and to San Francisco Bay itself. * Superbly illustrated with 139 color photographs, 41 drawings, and 29 maps * Covers Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano, and Sonoma counties * Gives clear, nontechnical explanations of complex topics including plate tectonics and the Bay Area's fault systems * Suggests locales in parks and open space preserves to view Bay Area geology in action Non sono state trovate descrizioni di biblioteche |
