Brief statement of problem and remarks (from collector):
Brachiopods, crinoids and snails occur in ferruginous sandstone and ferruginous shaly limestone that are probably the oldest unmetamorphosed rocks in the quad. Devonian(?) limestones (see collection Be21, Request A) 1/2 mile downstream on same creek are recrystallized. Statigraphic position of rocks of Be22 is uncertain because of poor exposures, but it is probably above the phyllite and subgraywacke units that are marginal to the schists, and may therefore set a limit to the age of the phyllite.
