-------- Original Message -------- Subject: SILS Bulletin 08-01 Geology of the United States (National Atlas Sheet) Date: Tue, 8 Jan 2008 13:21:16 -0700 From: Sheryle J Jackson <[log in to unmask]> To: maps-l Happy New Year to the group. Following is the latest bulletin. Please let me know if you are able to receive attachments from USGS throught your email. If so, I can attach a version of these bulletins. Several years ago when some of you were put on this mailing list, we could not do attachments to you. I have a feeling some of this has changed. I'm also sending a copy of the bulletin that covers information for the previous map that this map generalizes. Sherry *SILS Information Bulletin * *Number: 08-01 Geology of the United States* * National Atlas Sheet * *Date: January 8, 2008* *Stock #: 207470 (map) and 207471 (product announcement)* *Price: $7.00 plus, $5.00 handling per order* The National Atlas of the United States has released a new map illustrating the Geology of the United States. It shows: · the age, distribution, and character of rocks at or near the land surface; · the ages of sedimentary, volcanic, plutonic, and metamorphic rocks; · bedrock immediately beneath soils or thin surficial deposits; · the thick deposits along the lower Mississippi River, on the Atlantic and Gulf Coastal Plains, and in the deep basins of the western Cordillera; · the limits of continental glaciation; · major faults, impact structures, large volcanic calderas, and many other significant and interesting geologic features. This map measures approximately 27” by 31” and is a generalization of a geologic map of North America that was published in 2005 by the Geological Society of America. The original compilation was prepared at a scale of 1:2,500,000 for publication at a scale of 1:5,000,000. This generalized version is intended for viewing at scales between about 1:10,000,000 and 1:7,500,000. The majority of the map covers the conterminous portion of the U.S. with insets covering Alaska, Hawaii, and Puerto Rico and the Virgin Islands.

The Geological Society of America (GSA) has recently introduced the 2005 Geologic Map of North America. A work of beauty as well as science, the map is printed in 11 colors with approximately 700 shades and patterns. It distinguishes more than 900 rock units, 110 of which are off-shore. It depicts more than seven times as many on-land units as the 1965 map. Perhaps the most significant additions are detailed features of the seafloor, including spreading centers, seamount chains, and subduction zones. "Our knowledge of the Earth and how it works has grown exponentially over the last 40 years," said Jack Hess, Executive Director of GSA. "We are pleased and excited to offer this great mapping achievement to the scientific community." This map is the result of a cooperative effort by GSA, the U.S. Geological Survey (USGS), the Geological Survey of Canada (GSC), and the Woods Hole Oceanographic Institution (WHOI). John C. Reed Jr. (USGS) and John O. Wheeler (GSC) compiled the on-land geology, while Brian E. Tucholke (WHOI) mapped and compiled the seafloors. The Pikes Peak Lithographing Company, Colorado Springs, Colorado, printed the map. More than twenty years in the making, this 3-sheet map which measures 74”x39” and is at a scale of 1:5,000,000, illustrates approximately 15% of Earth's surface. It spans an area from the North Pole to Venezuela and from Ireland to Siberia. Unlike its predecessor, the map is not a static end-product. Because it was produced with digital technology, a digital database is planned by David Soller of the U.S. Geological Survey. According to Soller, "Geoscientists for years to come will be able to access and analyze the data behind the map. This will stimulate additional research, expanding our body of knowledge at an increasingly rapid rate." ### *The map is available for purchase through the Geological Society of America.* For additional information visit: www.geosociety.org/bookstore or contact GSA Sales and Service, [log in to unmask], 1-888-443-4472. This product comes rolled or folded. The non-member price of the rolled version is $155.00. Sheryle Girk-Jackson 303 202 4176, FAX 303 202 4633, email: [log in to unmask] Sheryle J.
