Comments on the geologic information

  • Geologic Description = Martin and others, (1915) examined hand samples from this occurrence and described them as quartz containing fragments of diabase, pyrite, and a little chalcopyrite. They then went on to speculate that this occurrence is similar to the Fairview and Iron Mask prospects (Martin and others, 1915). Tysdal and Case (1979) described the bedrock geology in this area as Cretaceous, pale to dark green aphyric to porphyritic pillow basalts with subordinate pillow breccia, tuff, and siltstones. Along the west shore of Resurrection Bay the pillows are right side up, dip 30 to 50W, and the long axes of the pillows and pillow bifurcation plung westward down dip.
  • Age = Cretaceous.
