Geological Structures is an easy-to-use, highly informative photographic field guide that introduces the great variety of geological structures to be found all around us. Put another way, a geologic map is a cross-section of dipping and plunging structures projected on a horizontal plane. More information Geologic Map Symbolization. Geologic structures influence the shape of the landscape, determine the degree of landslide hazard, bring old rocks to the surface, bury young rocks, trap petroleum and natural gas, shift during earthquakes, and channel fluids that create economic deposits of metals such as gold and silver. The authors' beautiful photography, extended captions and accessible text make interpreting and understanding geological structures simple, whether you're an amateur enthusiast keen to learn or a more experienced geologist. 112 0 obj <>stream endstream endobj 101 0 obj <>stream
