Arizona Geology e-magazine for summer 2013 now online

The Arizona Geology Survey has just released its summer, 2013, issue of Arizona Geology which features seven articles.  See the whole issue at

Most interesting to me is the article: Ground-Source Geothermal Heating and Cooling: Sustainable and Affordable Energy for Arizona and the U.S.  The article begins:

“This past August 12th was the first day of the new school year for ~ 1,000 students at Lookout Mountain Elementary School in Phoenix, Arizona. The high temperature that day was a torrid 109 degrees Fahrenheit while inside the newly constructed 50,000 square foot wing of the school, temperatures were a balmy 76 degrees Fahrenheit, thanks to a new ground-source geothermal system that exchanges heat with the cooler earth hundreds of feet below the ground surface.”

The other articles:

Arizona Seismic Update – January – July 2013

“The Arizona Broadband Seismic Network documented over 50 earthquakes in Arizona from January to July 2013. The quakes were mostly located in northern Arizona and were at depths ranging from 1.4 to 26 km (0.9 to 16.25 miles depth)”

Earthquake Shakes North Rim Area

“On July 7that 1:38 MST, a magnitude 3.5 earthquake shook the towns of Fredonia, Jacobs Lake, and Havasu . The earthquake was followed by a series of aftershocks, with two registering Md ~ 2.0 and several in the 1.0 range.”

Digitizing, Cataloging, and Publishing Arizona’s Mining Legacy Online: Mine Maps, Reports, and Photographs

“In 2011, the financially troubled Arizona Department of Mines and Mineral Resources (ADMMR) and the Arizona Mining and Minerals Museum shuttered their doors. The Arizona Geological Survey (AZGS) received the Department’s maps, photos and manuscript collections. That year, AZGS began a comprehensive inventory of the 30 archival collections, creating finding aids1 for the more than 10,000 folders, 6,000 maps, and 7,000 photographs.”

Update on the STATEMAP mapping program in Arizona

“The STATEMAP program is a component of the National Geologic Mapping Act of 1992. STATEMAP is a matching fund program whereby State general funds are matched one-to-one by federal funds to support geologic mapping by the states. The Arizona Geological Survey (AZGS) has participated in the STATEMAP program since its inception, and has produced 1:24,000-scale geologic maps of a large fraction of the State with funding from this program.”

Making Geologic Maps with GIS

“Geologic map production begins in the field. Geologists spend several months traversing pre-defined areas of Arizona’s landscape to collect geologic information about that area. Geologists collect qualitative and quantitative information in the form of observations in a field notebook or on a topographic map. Geologists use a GPS (global positioning system receiver) to identify observation locations.”

Summary of oil and gas activity in Arizona – January to June 2013

Besides oil & gas, this article provides brief information on drilling for carbon dioxide, CO2 sequestration, geothermal energy, and potash exploration.
