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
  • New Mexico Geological Society Foundation
  • Friends of Mineralogy
  • City of Socorro
  • Grant County Rolling Stones
  • Friends of Mineralogy–Colorado Chapter

Featured Speaker: Dr. Brad L. Cross

An Overview of the Agates of northern Mexico and southern New Mexico

Brad's mineral interest is primarily focused on the agates of northern Mexico where he has travelled extensively, studying, and collecting from the various deposits in Chihuahua, Sonora, and Durango. As a young teenager, it was his collecting of agates in southern New Mexico that spurred a life-long devotion to the colorful agates of New Mexico and its sister states across the border in Mexico. Brad's extensive collection of agates has been featured in various gem and mineral shows throughout the U.S. as well as shows and museums throughout Europe.

Brad is author of “The Agates of Northern Mexico,” “Geodes: Nature's Treasures,” and “Gem Trails of Texas.” He is also currently working on an update and revision to “Gem Trails of New Mexico” as well as “Majestic Treasures: The Colorful Agates of Mexico,” both of which are scheduled to be released in 2020.

Brad received his geological sciences degree from the University of Texas at El Paso. He is currently a Supervising Hydrogeologist with WSP in Austin, Texas.
