Overview of the Geology of Cosmetic Talc Formation and Morphology of Amphiboles

Source

Two cosmetic talc districts located in Val Chisone and Southern Vermont will be described regarding geologic formation and accessory mineral assemblages. Cosmetic talc is currently defined as having 98% or greater talc content. While uncommon in cosmetic talc ore, amphibole minerals, such as tremolite, may be found in rock assemblages adjacent to the talc. Classification of amphibole morphological features will be described for two categories: asbestiform and nonasbestiform.
