Sills and dikes of qtz monzonite up to 20' thick extend out into the sediments. Aplite dikes cut the sills & sediments and appear to be late stage differentiates from the qtz monz. Stock. The sediments have been pyrometamorphosed in a zone 50- to 100-ft. Along the contact of the stock. Scheelite occurs in tactite along the contacts of the stocks, dikes, and sills. Both as large masses and as disseminated grains most of the scheelite is concentrated within 20 ft. Of the stock and within 5 feet of dikes and sills. Scheelite is also present in calcite veinlets which are locally abundant enough to form stockworks.
