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.

USGS also offers a free product announcement, #*207471, *describing the
map to anyone needing copies for shows, conferences, etc. Copies are
limited. The same ordering procedures apply.

*New Geologic Map of North America Illustrates Discoveries and Advances
in Geoscience*

Boulder, Colo. – The last definitive geologic map of North America was
published before the theory of plate tectonics was widely accepted, back
in the days when impact craters were known simply as "anomalies" and
knowledge of ocean floor geology was in its infancy. 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."
