s geologic map of north america compiled by john c reed jr john o wheeler and brian e tucholke the new geologic map of north america covers ~15 of earth s surface and differs from previous maps in several important respects it is the first such map to depict the geology of the seafloor the first compiled since the general acceptance of plate-tectonic theory and the first since radiometric dates for plutonic and volcanic rocks became widely available it also reflects enormous advances in conventional geologic mapping advances that have led to a significant increase in the complexity of the map the new map printed in 11 colors distinguishes more than 900 rock units 110 of which are offshore it depicts more than seven times the number of on-land units as are shown on its immediate predecessor as well as many more faults and additional features such as volcanoes calderas impact structures small bodies of unusual igneous rocks and diapirs when displayed at earth science institutions and libraries this map is sure to impress viewers with the grand design of the continent and may inspire some to pursue the science of geology the new geologic map of north america is also a thinking map a source for new interpretations of the geology of north america insights into the evolution of the continent new exploration strategies for the discovery of mineral and energy resources and the development of better ways to assess and mitigate environmental risks and geologic hazards 3 sheets 74 × 39 scale 1:5,000,000 28 p text cia pe comprehensive fer of landstate o f t h e a r t al price rigin o csm001f 3 folded sheets $150.00 member price $120.00 csm001r 3 rolled sheets $155.00 member price $125.00 ow n csm001f folded list price $75.00 new member price $52.50 csm001r rolled list price $80.00 new member price $57.50 gsa sales and service p.o box 9140 boulder co 80301-9140 usa 303-357-1000 option 3 · toll-free 1-888-443-4472 · fax 303-357-1071 www.geosociety.org al eci er ff o
