A PDF version of this announcement is also available.

The New Mexico Mineral Symposium provides a forum for both professionals and amateurs interested in mineralogy. The meeting allows all to share their cumulative knowledge of mineral occurrences and provides stimulus for mineralogical studies and new mineral discoveries. In addition, the informal atmosphere encourages intimate discussions among all interested in mineralogy and associated fields.

This year’s symposium will consist of a day and a half of formal papers presented in 30-minute time blocks. Papers will focus on mineral occurrences from New Mexico and adjacent states, as well as Mexico. A few selected papers may be presented from other parts of the world.

The Mineral Symposium is organized each year by the Mineral Museum at the New Mexico Bureau of Geology and Mineral Resources.

Sponsors this year include:

  • Albuquerque Gem and Mineral Club
  • Chaparral Rockhounds
  • Los Alamos Geological Society
  • Grant County Rolling Stones
  • Friends of Mineralogy
  • White Mountain Gem and Mineral Club
  • Friends of Minerology – Colorado Chapter
  • City of Socorro

Featured Speaker: Dr. Peter K.M. Megaw

The Santa Eulalia Mining District, Chihuahua, Mexico

Dr. Peter K.M. Megaw, Consulting Geologist President of IMDEX/ Cascabel and co-founder of Minera Cascabel and MAG Silver, has 40 years involvement in Mexican geology and is a frequent speaker at international academic and technical symposia. His Ph.D. work at the University of Arizona was an exploration-focused geological/ geochemical study of the Santa Eulalia Ag-Pb-Zn District, Chihuahua and Carbonate Replacement Deposits (CRDs) in general. He has published extensively on CRDs in geological and mineralogical journals and books. He and his team are credited with several significant discoveries for which Peter was awarded the Society of Mining Engineers 2012 Robert M. Dreyer Award for excellence in Applied Economic Geology and the 2017 Prospectors and Developers of Canada's Thayer Lindsley Award for significant international discoveries.

Peter has been a passionate mineral collector since first setting foot in Santa Eulalia in 1977. He moved to Tucson in 1979 and quickly joined the Tucson Gem and Mineral Society™, serving in most roles (except Treasurer) over the years. He took on the job of Exhibits Chair for the Tucson Show in 1984, a job he has kept for most of the last 34 years, giving him the opportunity to visit most of the world's major mineral museums with a special eye out for what they should bring to Tucson. A combination of the above led him to be awarded the Carnegie Mineralogical Award for 2009. Peter has published a number of award-winning papers in popular mineralogy publications. Peter's latest publication is the Jan-Feb, 2018 issue of Mineralogical Record, devoted to the Mineralogy of the Santa Eulalia District in Chihuahua Mexico.

Mineral Symposium Field Trip — Friday, November 9th, Chupadera Copper Mine

The Chupadera copper mine is located east of Socorro in the Quebrada s area. The mine is classified as a red bed copper deposit with azurite, malachite, and chalcocite the main ore minerals. Associated with the mineralization are some large calcite veins that display multi-colored fluorescence. In addition, orange, dog tooth crystals that fluoresce red have also been collected. A large variety of fossils can also be found in the area around the mine. Meet in the Macey Center parking lot at 9:00 a.m. for escort to the mine by Philip Simmons. The last portion of the access road is rough and 4WD vehicles are recommended. As the symposium date approaches contact for more information.
