Geologic setting

Geologic description

The rocks in the vicinity of Lowrey's Ledge are Paleozoic greenschist-facies metamorphic rocks of the Nasina Series (Szumigala and others, 2002). Spurr (1898) observed quartz veins in schist that contain free gold and minute specks of iron and copper pyrites (chalcopyrite?). Free gold occurs in nearly horizontal quartz veins that are 10 to 12 inches thick (Eberlein and others, 1977). The quartz veins are parallel to the foliation of the schist. One specimen of quartz contained a gold flake that was about 0.003 inch in diameter. There is no record of any mining.
