Regional Significance of Recent Correlations Across the Murphy Tectonic Ridge, Westmoreland Area

Stratigraphic correlations across the Mur- phy Tectonic Ridge are crucial to regional corr. elations between the Mount Isa and McArthur River areas. Recent work in the Westmoreland and surrounding areas has substantiated the earlier general correlations between the Mount Isa and McArthur River sequences. The Mount Isa and McArthur Groups, and their equivalents, remain prime prospecting targets for major lead-zinc deposits of the Mount Isa and R.Y.C. type. A prospective area for Redbank-type copper mineralization is suggested.
