Nov 03, 2014 (K Kettles) - The area underlying the occurrence is comprised of mafic metavolcanics and metasediments. All of these units strike to the northeast and have nearly vertical dips. The mafic metavolcanics are primarily composed of pillowed and variolitic flows. Stratigraphic tops are to the west-northwest. The metasediments consist of interlayered graphitic-argillite and chert beds and underlie the mafic metavolcanics.
