The Thursday, 13 November 2014, Friends of Mineralogy, Colorado Chapter meeting will have Gary Zito present the "Geology and Minerals of the Stove Mountain-Fairview-Cheyenne Canyon are, near Pikes Peak, Colorado Springs."
The meeting will be held in the Bighorn Room, formerly the Africa Station room, on the third floor of the Denver Museum of Nature and Science starting at 7.30 PM. Members and guests can attend the meeting by entering the museum from the north volunteers and employee entrance door. Ask the evening guard for direction to the third floor elevators or escalator.
Gary L Zito received his B. S. Geology and Chemistry from the University of Colorado, Boulder. After starting out with Barringer Laboratories, as an Analytical Chemist of Mine Ore and Effluents, he finished his career after 25 years as the Vice President of Barringer Laboratories. Currently he is the Electron Microscope Laboratory Manager, Department of Metallurgical and Materials Engineering at the Colorado School of Mines, a position he has had for 12 years. He has been a co-author in several mineralogical and biological technical papers. He has been an active collector of Colorado minerals for more than thirty years. Rocks & Minerals published his most recent article with Sarah Hanson on the Stove Mountain area in the May-June issue this year (2014).
Geology and Minerals of the
Stove Mountain/Fairview/Cheyenne Canyon Area,
near Pikes Peak, Colorado Springs.
The miarolitic pegmatites in the Stove Mountain area of Colorado have provided numerous attractive specimens of quartz, microcline, albite, and fluorite, as well as rare accessory minerals. In total, forty-seven different minerals have been found in this area. This area contains so many different minerals due to the presence of both the Pikes Peak Granite and the peralkaline Mount Rosa Granite and the secondary processes that are unique to this area. These secondary processes are responsible for many of the later accessory minerals.
Attractive specimens of smoky quartz, microcline, albite, muscovite and fluorite which compose the major minerals in these cavities, have been intensive searched for by collectors since the 1880s. Some of these will be illustrated.
The later formed, secondary minerals, are of special interest to collectors due to their rarity. These are fluocerite and bastnaesite, which are often found in association, columbite and pyrochlore, also often associated, genthelvite, danalite and kainosite. A discussion of these minerals will form the majority of the presentation.
