Geologic setting

Geologic description

This occurrence consists of magnetite layers and lenses up to several inches thick in banded chert and argillite that is interbedded with a pyroxene-bearing flow or dike (Sainsbury, 1961). Deformed limestone, banded chert, and calcareous argillite crop out to the south. The rocks are probably part of the Descon Formation of Silurian and Ordovician age (Eberlein and others, 1983; Brew, 1996). Several samples collected by Maas and others (1992, 1995) contained up to 72.13 percent iron but insignificant amounts of other metals.
