...Anton R. Chakhmouradian; Mark A. Cooper; Ekaterina P. Reguir; Meghan A. Moore Abstract Zoned crystals of carbocernaite occur in hydrothermally reworked burbankite-fluorapatite-bearing calcite carbonatite at Bear Lodge, Wyoming. The mineral is paragenetically associated with pyrite, strontianite...
