Description
The Daisy Fault was named for the Daisy fluorspar vein, which in turn took its name from the abandoned Daisy Mine. The fault and vein are part of a complex system of fractures along the southeast margin of the Rock Creek Graben. The Daisy Fault strikes N20°E, dips 70° to 80°W, and has as much as 350 feet (106 m) of normal displacement. Bastin (1931) reported that slickensides on the fault plane varied in plunge from 10°S to 80° , indicating a component of strike-slip. He also stated that the western or hanging wall of the vein is a postrnineralization fault plane, whereas the ore is "frozen" to the east wall.
