Field Trip Details

Porphyry and Skarn Systems of the Southwest U.S.

Pre-Conference Field Trip departing from Phoenix, AZ, USA returning to Phoenix, AZ, USA

September 21-27, 2014

Field Trip Leaders

William X. Chávez, Jr. (SEG 1990 F) | wxchavez@nmt.edu | Professor of Geological Engineering, New Mexico Institute of Mining and Technology

Erich U. Petersen (SEG 1986 F) | eupetersen@gmail.com | Professor, The University of Utah

Description

Beginning in Phoenix, Arizona, this field-based course will examine the geologic settings and geochemical characteristics of large hydrothermal systems, with emphasis on porphyry, porphyry-related breccia "pipes," and skarn-style ore deposits. Starting in Phoenix, participants will visit porphyry systems showing well developed supergene profiles and deeper, K-silicate assemblages characteristic of well-developed hydrothermal alteration-mineralization. Exposures in the Globe-Miami District and those near San Manuél, Arizona, offer the opportunity to examine early alteration-related veining styles and vein paragenesis assemblages. Skarn-type systems and their relationships to porphyry ores will be discussed at several ore deposits, allowing participants to compare and contrast porphyry and skarn geochemical features. Visits to key outcrops will reinforce discussions dealing with the importance of regional and local geologic settings for southwestern USA hydrothermal systems.

In-the-field and evening presentations will complement field observations and include discussions of the applications of activity and Eh-pH diagrams to exploration, mining, and geometallurgical considerations. As such, this course is designed for exploration and mining professionals who are involved with exploration and ore targeting; this course is also appropriate for graduate students and upper-division undergraduate students with interest in economic geology and the application of geochemistry to minerals exploration. This course will be given in English and Spanish.

Departure on September 21 is 12:00 pm and participants need to arrive in Phoenix no later than 10:00 am. Departure on September 27 is any time in the morning.

Attendee Maximum: 20

Non-Ferrous Mineralization Associated with the Wawa-Abitibi Terrane and Duluth Complex Cu-Ni-PGM Deposits, Northeastern Minnesota

Pre-Conference Field Trip departing from and returning to Duluth International Airport, MN, USA

September 22-25, 2014

Field Trip Leaders

George Hudak (SEG 2011 F) | ghudak@nrri.umn.edu | Director, Minerals Division, NRRI, University of Minnesota Duluth

Dean Peterson | dpeterson@duluthmetals.com | Senior Vice President, Exploration, Duluth Metals Limited

Description

After more than 100 years of iron mining, Minnesota is on the cusp of developing a new, non-ferrous mining industry. The world-class Duluth Complex mineral district ranks second in contained copper, third in contained nickel, and second in contained PGM (i.e., platinum, palladium, and gold) worldwide. Successful resource development has the potential to result in an entirely non-ferrous mining district that may be similar in scale to the region's existing taconite mining and processing industry. Additionally, recent studies indicate that Minnesota's Wawa-Abitibi Terrane may hold considerable potential for hosting additional non-ferrous and/or precious metals resources, including copper, zinc, and gold.
