Arizona Geological Society

Welcome to the Arizona Geological Society

Three Members Recognized for their 50-year Membership in Arizona Geological Society

James Briscoe

James Brisco

James Briscoe has a BS and MS in Geology from the University of Arizona. He is a Registered Professional Geologist in the States of California and Arizona since 1969 and 1972 respectively. James is one of the founders of Liberty Star Uranium & Metals Corp. He has been involved in mineral exploration and discoveries for the past 50 years. He is credited with expanding porphyry copper ore reserves at Silver Bell, Arizona and identifying major gold deposits in the Randsburg District in California. He also aided in the discovery of the McDermitt open-pit mercury mine in Nevada. Mr. Briscoe co-discovered and co-owned the Wind Mountain gold-silver mine in Nevada. In Alaska, he identified the Big Chunk caldera and the copper-gold-moly potential continuation from the Pebble mine and alteration zone. James Briscoe also identified the Tombstone Caldera in 1988. He has served as either an officer and or director of three other publicly trading exploration and development companies.

Ted Eyde

Ted Eyde

Ted Eyde is an Engineering Geologist for Pedregosa Basin Resources LLC. He also owns the Gadsden Sonora Holdings Company LLC with his wife. Ted grew up in Butte, Montana, where he received an MS in Geological Engineering from Montana Tech. Afterwards, he worked for the Union Carbide Corporation on specialty and performance industrial minerals. Ted moved to Arizona in 1959 to assist the company with locating natural zeolite deposits. He eventually discov-ered a large cabazite deposit, which is still being used today. He was the presi-dent of the Society for Mining, Metallurgy & Exploration (SME) national chap-ter in 1991. He is also the cofounder of the Mining Foundation of the Southwest. The Foundation promotes public understanding and education related to mineral resources and the mining industry, and funds educational projects each year in the southwest and Mexico.

Peter Kirwin received his BA in Geology at Dartmouth College in 1957, and his MS in Geology and Geophysics at the University of Minnesota in 1963. He started his career in Tucson in the summer of 1960, following two summers in the Canadian bush. He lived in Arizona towns such as Tucson, Wickenburg, Kingman, and Cottonwood. He worked for 40 years in metals exploration in ten U.S. states, 3 Canadian provinces, all Australian states but Tasmania, Sinaloa, and New Guinea. He worked for many companies, including Kennecott (BCMC), NJ Standard (Exxon/Humble), Inco, Cy-prus, Copper Range, Lac, and Siskon, in management positions up to district manager and U.S. exploration manag-er prospecting for various deposits (copper, molybdenum, gold, poly metallic, etc.). His last consulting job in Arizona was in the Globe-Miami District for Cyprus Mines, which led to a new recognition of the structural setting and mode of emplacement of the Miami-Inspiration deposits.


Arizona Mining Review March 26, 2018


On 26 March 2018, Arizona Mining’s Don Taylor, discoverer of the world-class Taylor zinc-lead-silver deposit in the Patagonia Mountains of southeastern Arizona, spoke with AZGS for the 44th episode of the Arizona Mining Review e-Video Magazine. You can view that 11-minute interview at our AZGS Youtube channel.


AGS By-Laws Change Effective March 6, 2018

Effective March 6, 2018, the AGS membership has voted to change Article IX, paragraph 2(d) of the AGS Bylaws from:

TO:

(d) 50-Year Members – members in good standing who have maintained membership for a minimum of 50 years shall have the privileges of a full member of the Society and will be excused from further payment of dues.


Arizona Mining Review February 15, 2018


Michael Conway of the Arizona Geological Survey interviews Bob Comer, President of the American Exploration and Mining Association at the AEMA's Winter Reception at the Double Tree Tucson.  I recommend viewing this interesting video about Arizona's mining industry.


USGS 2019 Budget takes a Shellacking


If President Trump's 2019 budget becomes law, the U.S. Geological Survey budget will fall 20% to $859.7 million.  Full-time employees in turn, will be reduced from the current 4,876 to 3,677; a diminution of about 25%.

Peter Ward Presented an Alternative View on Climate Change at January 2018 Meeting


On Tuesday, January 2, 2018, Peter L. Ward presented "Bringing Peace to the Climate Wars."   In the linked video, he presents an alternate view on what controls climate change. Ozone depletion theory provides a better explanation of scientific observations than the Greenhouse Gas model.  Depletion of the ozone layer by gases released by volcanic activity provides a clear, direct and comprehensive explanation for climate changes during recent years and throughout earth's history.

Anyone who wishes to learn more about Peter Ward's research on climate change may visit his web site at What Really Causes Global Warming?  Greenhouse Gases or Ozone Depletion. It you have any comments or questions about this presentation or his research, you can contact Peter at peward@wyoming.com.

Future of the AGS is Uncertain by David F. Briggs, AGS President


Since its inception in 1948, the Arizona Geological Society (AGS) has been an organization run by members, who have volunteered their time to conduct its business.  Over the years, older members have been succeeded by younger professionals providing an unbroken chain of experienced leadership that has allowed the Society to flourish.  The efforts of many who have volunteered their services have made it possible for the AGS to  accomplish its mission to promote and encourage interest in the geology of the State of Arizona.

The Arizona Geological Society has sponsored field trips and symposia and published numerous field trip guidebooks and digests at irregular intervals.  Monthly dinner meetings with presentations on a wide variety of interesting topics have provided a forum for stimulating discussions, valuable networking opportunities, and camaraderie among colleagues and others with similar interests.  The AGS has supported the next generation of geosciences professionals through academic scholarships to students at the University of Arizona, Arizona State University and Northern Arizona University.  It has also helped educate government officials and the public about the importance of geology.

I have heard some members question the relevancy of the AGS.  To be sure, our level of activity has waxed and waned over the years, but I believe it is misguided to consider the AGS irrelevant.  All of the activities, mentioned above, are relevant to the Society's mission.  However, there is one thing that is certain, none of its accomplishments would have been possible had members not volunteered their time to make it a reality. 

In recent years it has become increasingly difficult to find volunteers, who are willing to make a commitment to serve on the Society's governing board and other supporting activities.  Unfilled positions and recent resignations from the Executive Committee now seriously threaten the viability of the organization itself.  The AGS currently needs volunteers to serve as Treasurer, Vice Treasurer, Secretary and Vice Secretary during 2018.  Unless these positions are filled, AGS's ability to conduct business is in question.

The Arizona Geological Society cannot function without membership participation.  Take a moment to consider what you can do to help the Society.  Whether it prospers and finds new and innovative ways to serve the geological community or becomes extinct; its future is in your hands.  The Society's success in carrying out its mission depends on you and the amount of work you are willing to contribute to this endeavor.  In addition to the satisfaction of knowing your efforts make a difference in our local world, you will gain a wider group of friends and colleagues and the appreciation of all AGS members.
