Abstract
Hyolithids and other Lower Cambrian fossils occur within marbles in low-stage metamorphic rocks (Forktree Limestone and Heatherdale Shale) forming the core of a north-east plunging regional anticline, overturned to the south-east. A great thickness of partially bioturbated Kanmantoo Group metasediments, dominantly clastics, but including sulphide-rich calc-phyllites of the Talisker Calc-siltstone, conformably overlie the Heatherdale Shale. The rapidly deposited elastics, including numerous thin conglomerates, are interpreted as products of the Kangarooian Movements known to have affected the region now occupied by Investigator Strait and Gulf St. Vincent. The newly proposed stratigraphic subdivision for that part of the Group discussed should lead to a more reliable picture of the occurrence and the relationships of these rocks to other sequences within the Mt. Lofty Ranges and Kangaroo Island.
