Professional Organizations
The
USGS (United States Geological Survey, www.usgs.gov)
is a very good source for all matters concerning geology. The
organization not only has extensive databases on every known aspect of geology,
but also has educational programs for geology students.
Another professional organization is the AAPG (American Association of
Petroleum Geologists, www.aapg.org).
This organization is centered around energy exploration but also gives
the student vast databases on a great variety of subjects in the geological
sciences.
