Cinnabar, Quartz, Mica Group
Cerreto Piano, Scansano, Grosseto Province, Tuscany, Italy
Typical of the locality, this specimen is composed of a nodular aggregate of massive, botryoidal Cinnabar formed as a floater within a granular Quartz and Mica group matrix. The black massive mineral may be one of the hydrocarbons sometimes associated with mercury-bearing mineral deposits.
