Lamprophyres collected in 1971 from near Radium Hill and dated as Ordovician are very similar petrographically to the alkaline and lamproitic rocks of Ordovician age in the area between Truro and Frankton. A specimen described as of intermediate composition appears petrographically to be a variant within the lamprophyric suite. The province of lamproitic lamprophyres may be of boomerang shape, with a N-S limb along the eastern edge of the Mount Lofty Ranges and a NE-SW limb along the G7 lineament. In New South Wales the G7 lineament extension is called the Darling Lineament, and this feature is also the locus of alkaline, possibly diamondiferous intrusives.
