Abstract

This dry hole, on the east flank of the Wills Mountain anticline, in Circleville district, was completed in the repeated basal member of the Lurich formation, at a total depth of 13,000 feet. The borehole penetrated Ordovician and Cambrian formations in normal sequence to near the base of the Elbrook dolomite where a thrust fault was met, below which was an overturned complexly deformed section of Middle Ordovician limestones. The last 1,529 feet of Middle Ordovician limestones were in normal sequence. Twelve metabentonite beds were used as an aid in correlating the repeated formations below the thrust.
