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. Many papers will focus on mineral occurrences from New Mexico and adjacent states, as well as Mexico. Other selected papers may be presented from other parts of the world. An informal pre-symposium social and tailgating session will be held at local motels beginning on Friday, and will last through the weekend.

Field Trip: Lake Valley Mining District — Friday, November 7

The Los Alamos Geological Society is hosting a field trip to the historic Lake Valley Mining District on Friday, November 7th, in conjunction with the 44th Annual New Mexico Mineral Symposium.

Lake Valley was a silver-manganese mining district. Silver was discovered in 1876, and the area was extensively mined until the silver crash in 1893 (Donegan et al., 1965; McLemore and Nutt, 2002). The Lake Valley district includes the famed Bridal Chamber, which was found in 1881. The Bridal Chamber was among the richest silver deposits ever mined (Eveleth, 1986). The spectacular Bridal Chamber ore body composed of silver chlorides and silver bromides was nearly two hundred feet long and 25 feet thick (Clark, 1895; MacDonald, 1909: McLemore and Nutt, 2002). Chlorargyrite (cerargyrite; AgCl), the main high-grade ore taken from the Bridal Chamber, was mined out by the late 1880s. Manganese minerals, mainly manganite and pyrolusite, were mined in the Lake Valley district during and after World War II (Creasey and Granger, 1953). No significant mining activity has occurred in the area since 1959 (McLemore and Nutt, 2002).

Micromineral Aficionados Gathering — Friday, November 7

For the third time we are holding a new feature to the symposium, The Micromineral Aficionados Gathering. The Micromineral Group of the Albuquerque Gem and Mineral Club will host a gathering for all interested in the small but glorious world of microminerals, i.e. specimens that require magnification to be truly appreciated. The gathering will be held in the Mineral Museum on NM Tech campus, Rm. from 9am - 4pm.

There will be two talks presented during this year's gathering:

  • Scott Braley on minerals of the Bullfrog No.2 mine, North Magdalena District
  • Mike Gobla on the Sherman Mine in Leadville, Colorado.

This will be an informal gathering to look at and talk about (some exaggeration is expected) microminerals and their localities. Bring material you are willing to trade with other aficionados. We will provide many flats of giveaway material and are looking forward to seeing what you bring to share. We will provide a few extra microscopes and are happy to share ours but if you have your own it would be a good idea to bring it. The event is free and open to all. Questions? jaypenn246@gmail.com
