A volcanic sublimate or fumarolic sublimate is a mineral which forms directly from volcanic gas, by the process of deposition, during an eruption or discharge from a volcanic vent or fumarole.[1] Native sulfur is a common sublimate mineral and various halides, sulfides and sulfates occur in this environment associated with fumaroles and eruptions.
