Welcome to the Arizona Geological Society

2019 AGS Slate of Officers

Good Day All:

The Arizona Geological Society (AGS) is searching for volunteers to serve on the 2019 AGS Executive Committee. 

All officers, with the exception of councilors, serve for one (1) calendar year.  Councilors serve for three (3) years.  Don't be shy, self-nominations are common and acceptable.

The following offices require candidates:

  • President
  • Vice President of Programs
  • Vice President of Field Trips
  • Vice President of Marketing
  • Treasurer
  • Vice Treasurer
  • Secretary
  • Vice Secretary
  • Two (2) Councilors

In addition to the executive committee, the Arizona Geological Society is seeking someone to take charge of the AGS website.

During the coming year, the AGS will be involved in two new exciting projects, the University of Arizona's Gem and Mineral Museum in downtown Tucson and the Geological Society of America's Annual Meeting in Phoenix, Arizona.  The Society's success in carrying out its mission depends on  its members' willingness to contribute to these and other endeavors.  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.

Take a moment to consider what you can do to help the Society accomplish its mission.  You can self-nominate and you can nominate others, but you should contact that person prior to nominating them to gauge their interest in serving.

AZGS Hires an
Economic Geologist

We are delighted to announce that the AZGS offered the position of Research Scientist in Economic Geology to Carson Richardson this week, and he has accepted the offer. Carson is a Ph.D. candidate in the Dept. of Geosciences, University of Arizona. He is finalizing his Ph.D. research and will join our staff in January 2019.

 

We received ~35 applications, interviewed 7 candidates, and brought in 4 finalists for presentations and interviews. Each of the finalists has strong qualifications for this position, and we appreciate their willingness to share their ideas with us.

 

Carson’s chief task will be to build an economic geology program to support our mission to ‘provide technical advice and assistance to industry while encouraging the wise and prudent use of Arizona lands and mineral resources.’ He will join our geologic mapping efforts, focusing on mapping and assessing mineralized zones. He will also track mining trends in Arizona and will be the Survey’s primary liaison to the mineral exploration and mining community.



Carson on Outcrop of Breccia

 

Bio. Carson Richardson grew up near Peru, Indiana – the amateur circus capital of the world. He received his BS in Geology and Anthropology from Ball State University in 2012, and his MS in Geosciences from the University of Arizona in 2014. He has continued at UA working on a PhD, with an anticipated graduation date of Spring 2019. Carson’s research interests span economic and structural geology, but with particular emphasis on understanding the magnitude and timing of post-ore extensional faulting and its implications for the modern distribution of mineral resources.


U of A Gem & Mineral Museum


Bob Downs, Univ. of Arizona Mineral Museum Curator & Prof. of Geosciences, is leading the effort to build out a University of Arizona Gem & Mineral Museum (UAGMM) at the former Pima County Courthouse in downtown Tucson. Building renovation is well underway with the museum scheduled for a soft opening at the Courthouse in Jan. 2020.

Two of the museum’s chief organizers, Eric Fritz (Mgr.) and Les Presmyk (Mining Engineer & mineralogist), approached AGS’s Jan Rasmussen (former Curator of the Arizona Mining and Mineral Museum in Phoenix) and AZGS’s Mike Conway about helping design an exhibit focusing on the geology of Arizona.

Jan and Mike have begun pulling together ideas for an Arizona geology narrative – one idea involves building a digital display showcasing Ron Blakey’s marvelous paleogeographic reconstructions of the Colorado Plateau and environs, complemented by geologic scenes, lithologies, and interviews as the cornerstone of the exhibit. 

HELP! But we want your help in gathering ideas on the elements of narrative (with visuals) expounding on Arizona’s geologic history. In short, we want your ideas, sketches, brainstorms, and musings to help us rough out a draft design by mid-July 2018 – 3 weeks away!  This is an important opportunity for you to influence a future wide audience about Arizona geology.

LOGISTICS

Arizona Geology Exhibit. Approximately 75 square feet is set aside for an Arizona Geology exhibit. An additional 15 square feet is provided for a porphyry copper display. (Will Wilkinson. FMI retired, is taking the lead here.)  

Audience. UAG&MM organizers anticipate a largely non-science audience of considerable age range and with limited knowledge of geologic concepts.

Timeframe. Time is short. AGS & AZGS representatives meet with the UAG&MM design team in mid-July, so the sooner you share your ideas the sooner we can begin evaluating them.  

Financial Resources.  Bob Downs, Eric Fritz and others in the management will pursue the financial resources for final exhibit design and construction.

How to help! Please send your ideas, sketches, and experiences gleaned from other mineral or natural history museums to Mike and Jan at the e-mail addresses below. We can meet to brainstorm ideas before the July 3 AGS meeting to discuss ideas.

2018 AGS Spring Field Trip to Jerome

Overview of the United Verde Pit

On Saturday, April 21, 2018, the weather was excellent as approximately 60 members and guests of the Arizona Geological Society visited Freeport-McMoRan's United Verde volcanogenic massive sulfide deposit, located in Jerome, Arizona.   Participants included a number of professionals; both active and retired, as well as university facility and students.

Participants listen to Presentation on the History of the Verde Mining District

Following a brief orientation by our hosts, David Briggs gave a brief presentation on the history of the Verde mining district from an elevated area near the General Office, where attendees could view many of the important historical landmarks in and around the United Verde pit.   For those who wish  to learn more about Jerome, a comprehensive article on the history of the Verde Mining District, can be downloaded from the Arizona Geological Survey's web site.


Paul Lindberg Presentation at United Verde Pit Overlook

Participants hiked from the General Office to an overlook at the United Verde open pit, where Paul Lindberg discussed the volcanogenic massive sulfide model that describes how the United Verde ore deposit formed.  He also employed a block model to describe the structural evolution of the Verde mining district and its impact on the development of supergene enriched zones at the United Verde and United Verde Extension deposits.

Dave Briggs presents Honorary Life Membership to Paul Lindberg

At the conclusion of Paul's presentation, the Arizona Geological Society awarded Paul with a Honorary Life Membership in recognition of his exceptional contributions to Arizona Geology over nearly five decades.

Particpants Enjoy Lunch at United Verde Pit Overlook

The field trip participants enjoyed lunch at the overlook of the open pit, where many examined the altered Cleopatra Rhyolite in the footwall of the massive sulfide ore body and collected representative samples.

Jerry Waegli and Ralph Stegen Discuss Geology of the United Verde Ore Body

After lunch, participants hiked back to the General Office, where Jerry Waegli and Barbara Neilsen made their presentations.  Jerry Waegli discussed various aspects of the United Verde massive sulfide ore body and various exploration programs that have occurred since the mine's closure in 1953, while an interesting presentation on Freeport-McMoRan's reclamation activities in the district was made by Barbara Neilsen. 


Museum at Jerome State Historic Park

The formal field trip ended around 1:30 PM, giving those participants who wished learn more about the area an opportunity to visit the museum at the Jerome State Historic Park and the Jerome community.

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.


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.
