Abstract

In 1928 (Lewis, 1928) one of the present authors reported Silurian
quartzite conglomerates in the valley of the D'Entrecasteaux River-Recherche
Bay area-South-Western Tasmania. In so doing he was
influenced by Twelvetrees (1915). Considering the matter more
recently, it appeared that this occurrence might be of glacial origin.
If this proved to be correct, the original site of these rocks must
be westward of the La Perouse Range. An opportunity to visit
this difficult locality has now presented itself. The rocks in question
are undoubtedly of glacial origin, but they are Triassic grits,
and not of Silurian age. No one can now be sure whether the series
is the same as that reported by Twelvetrees, but from his very
brief description this may be so. In any case, some further
observations were made which are worth recording. This paper
must he cconsidered merely as an amplification of the previous
account (Lewis, 1928).
