Notes on the section at One Tree Point, near Hobart

More than thirty years ago Mr. R. M. Johnston, in a paper read before this Society, pointed out the great geological interest of a section exposed on the western side of Brown's River Road, near One Tree Point.
Mr. Johnston has shown that we have here a volcanic rock of the Basalt-group overlying sedimentary rocks, which contain an abundance of plant remains.
Many years later Messrs. McLeod and White examined the Basalt, and came to the conclusion that it is a basalt in which Fayalite, the red variety of Olivine, has replaced the Augite and Olivine.
