Formation of the breccias and associated hydrothermal alteration was likely due to multiple episodes of explosive brecciation related to magmatic fluid overpressures developed in a crystallizing, fluidsaturated granitic magma (Kooiman et a!. 1986; Sinclair et a!. 1988). The subvolcanic porphyry-type tungsten-molybdenum deposits and the younger tinpolymetallic vein-type or replacement bodies are genetically related to the granites, which have been dated to 330-340 Ma (K-Ar and Rb-Sr methods; Kooiman et a!.
