Comments on the geologic information

  • Geologic Description = Red-brown concretions in Kayak Shale are confined to an approximately 6 m-thick section of black shale. They range from 4 cm rounded forms to 7.5 x 38 cm flattened, elongate forms. The concretions contain quartz, calcite, barite, siderite, and pyrite as septarian fracture fillings along with minor sphalerite and trace galena. At the base of the shale, a 10 cm-thick red-brown cherty ironstone bed contains minor sphalerite. The ironstone bed is exposed along strike for 6 m.
  • Age = Mississippian
