Geology
AlterationFluorite and beryllium-bearing mineralization is thought to be a type of distal alteration to tin metallizing sytems in this area. Mass balance calculations show significant SiO2, Al2O3, alkali, and fluorine enrichment with mineralization (Sainsbury, 1968, p. 1567). The limestone is commonly dolomitized but the relation of this alteration to sulfide and fluorite mineralization is not clear.
