The glacial beds of Little Peppermint Bay, Tasmania

Little Peppermint Bay is a small arm of the sea on the western side of D'Entrecasteaux Channel, abont 27 miles south of Hobart. The nearest point at which the Channel steamers call is Woodbridge, or Peppermint Bay, about half a mile south of the beds described in this paper.The prevailing beds in the locality belong to thePermo- Carboniferous series, and have, over a large area, a fairly uniform dip to the S.E., at about an angle of 30C. They are intruded into by two distinct types of igneous rocks, viz., the Oyster Cove porphyries and the diabase greenstone, and, near the contacts, are disturbed to a considerable extent.
