Comments on the geologic information

  • Geologic Description = Chalcopyrite is present in quartz veins in mafic volcanic rocks.??These observations where likely made in rocks mapped as Precambrian volcaniclastic rocks of Redwacke Creek (Reiser and others, 1980). Potassium-argon dating of these rocks indicates Early Jurassic to Late Triassic ages which are not consistent with mapped field relations (Reiser and others, 1980).??Marker beds used in detailed mapping along the U.S.-Canada border consist of volcanicastic rocks that are Ordovician or Cambrian in age and likely stratigraphically equivalent to the Whale Mountain volcanics that contain a Late Cambrian fauna in their basal part (Kelley and others, 1992). Although the age of the volcaniclastic rocks of Redwacke Creek is uncertain and presumed to be Precambrian by Reiser and others (1980), work by Lane and others (1995) and Kelley and others (1992) raises the possibility that the volcaniclastic rocks that have reported to be mineralized are Cambrian to Ordovician in age: if so, the mineralization in them is not akin to mineralization in Precambrain volcanics in the Sadlerochit and Shublik Mountains.
