A hatchured weathering pattern is produced on the dolomite beds of the Ordovician Newala Formation near White Pine, Jefferson County, Tenn., distinguishing the dolomite from the limestone sequence. The hatchures are more abundant near an exposed small fault. Stained thin sections show many small fractures filled with calcite; the hatchures are localized where the calcite veinlets intersect the weathered surface. As the calcite was apparently introduced into tectonic fractures, abundance of hatchures may be useful as a guide to locate tectonic structures in areas with exposures of dolomite.
