Comments on the geologic information

  • Geologic Description = Kanagunut Island is underlain by intensely folded and faulted pelitic schist, granulite, and marble of Mesozoic or Paleozoic age (Sainsbury, 1957, p. 152-153; Berg and others, 1988). Red garnets as much as an inch in diameter, and smaller, dark red to black garnets, are abundant in a wide belt of pelitic schist and granulite on the western part of Kanagunut Island. Locally, the garnet-bearing layers are estimated to contain as much as 30 to 40% garnet. Garnet sands along the west coast of the island are beach placers derived from the schist.
