New Mexico Mineral Symposium — Abstracts

Minerals found in the carbonate rocks of the American Midwest are well crystallized, beautiful, and abundant. Spectacular crystals occur in a wide range of habits, color, and association with other minerals. Collectible minerals from the Midwest occur at mines located in Mississippi Valley-Type deposits, at limestone quarries, and within quartz geodes occurring only in rocks of Mississippian age.

The presentation will feature a great number of photos of the mineral species found at three important geode fields.
