Abstract
Unique feldspar porphyries, syenitic in appearance, and granitic in composition, form an unusually thick sill intruding pre-Cambrian Belt graywacke about eight miles south of Whitehall in southwestern Montana. Commercial deposits of gold and silver ores occur nearby, and may possibly be genetically related to the porphyry, although direct association is not evident. The geologic age is believed to be late Cretaceous or early Tertiary, and the sill may be related to the Tobacco Root batholith.
