Middle Miocene limestone from Cape Barren Island, Furneaux Group, Bass Strait

Abstract

In 1935 Mr. F. Blake of the Geological Survey of Tasmania visited Cape Barren Island in connexion with the underground water supply at Franklin Village, which is situated on Sandford Bay in the north-west part of the Island. He collected a small sample of fossiliferous limestone which he forwarded to the late Mr. F. Chapman, who was then Commonwealth Palaeontologist. No examination of the material was made at the time. Recently it came under the notice of the writer, who has made a detailed microscopic examination of it, with the following results:- The rock is a hard to friable, cream coloured, bryozoal limestone. The residue after washing contains numerous foraminifera and bryozoa, but the majority of the specimens are poorly preserved.
