Abstract

A visit recently paid to Port Cygnet has resulted in a discovery
which is not without interest from a scientific point of
view, if nothing more. Having had to traverse the Huon
district in all directions for several years past, in the discharge
of official duties, I had become tolerably familiar with its
principal geological features, which present few variations
from those that prevail in the neighbourhood of Hobart Town,
and the greater part of the Derwent basin. If a line be drawn
from the East Coast through Campbell Town to the Great
Lake, and thence southwards to Recherche Bay in a direction
nearly corresponding with the course of the 147th meridian,
the area included between this and the coastline is the only
large section of Tasmania in which there is no ground for
expecting discoveries of gold or other valuable metals. The
sedimentary rocks of the whole of this area may be described
in general terms as Upper Palaeozoic. They comprise the
carboniferous series, and probably pass upwards into the
counterparts of rocks now established in Victoria as Mesozoic,
and they are here and there overlaid by Tertiary and Post-tertiary
deposits. The whole series, to the Tertiary inclusive,
has been penetrated and intersected to an extraordinary extent
by trappean and basaltic rocks, which frequently hide the
sedimentary strata altogether from view over extensive tracts
of country.
