Where to Find Chalcedony in New Mexico

New Mexico chalcedony occurs across the southwestern volcanic country. The Apache Creek area in Catron County yields white, blue, and pink chalcedony rosettes in welded tuff, and the Luna County BLM ground near Deming produces small chalcedony nodules in rhyolite. The Bingham fluorite district in Socorro County carries violet-banded chalcedony as a gangue mineral with the fluorite and barite. Pinos Altos and the Burro Mountains add chalcedony with copper staining on old mining-district roadcuts. Most New Mexico chalcedony is dense and translucent; surface specimens are often coated in caliche that flakes off easily with mild acid.
