The Energy Minerals Division celebrated its 25th Anniversary in 2002. The Division emphasized to the AAPG membership that it was AAPG’s center of activity on energy minerals and unconventional energy resources. EMD originally focused primarily on coal, uranium, geothermal energy, oil shales and tar sands. However, its focus expanded and in 2002, EMD’s most active unconventional resource areas were coalbed methane, gas hydrates, and unconventional energy economics.

In early August, we learned that a Texas Sunset Review Board had recommended the elimination of the Texas Board of Professional Geoscientists. Our local AAPG-affiliated societies quickly organized an information campaign and defense for the TBPG. This shows the importance of strong, well organized local affiliates. This situation also raises several questions about the professional status of geologists in our society and how we view ourselves.

The famous phrase “I a geologist” is one from a young man 29 years of age named Charles Darwin. After his introduction to geology at the age of 21 by Adam Sedgwick, Darwin would eventually embark on the famous voyage of the Beagle which lasted from 1831 to 1836.
