Geology

Alteration processes:The limestone is commonly dolomitized but the relation of this alteration to sulfide and fluorite mineralization is not clear. Lamprophere dikes are kaolinized and locally contain disseminated tourmaline and fluorite. Fluorite veining and replacement is in effect a type of alteration here that can be thought of as distal alteration to more intense, tin metallization at depth. Mass balance calculations show significant SiO2, Al22O3, alkali, and fluorine enrichment with this type of alteration (Sainsbury, 1968, p. 1567).
