Of  Curnamona Province Distribution: Large domal outcrops at Binberrie Hill, Olary Domain. Outcropping granite bodies commonly occur as plutons up to several kilometres across, ranging down to small masses within migmatite. Relationships: Granite bodies commonly have broad, diffuse migmatitic aureoles within host Willyama Supergroup metasediments. These granites appear to have intruded across folds of the Olarian Orogeny (~1620-1580 Ma) but are affected by later events such as the Cambro-Ordovician Delamerian deformation.

Volcanogenic breccias, conglomerates, sandstones and siltstones exposed on Hiltaba Station in the southwestern Gawler Ranges. The Mount Friday Formation forms part of the upper Gawler Range Volcanics. It is underlain by the Eucarro Rhyolite and overlain by the Yardea Dacite. It is a correlative of the Mount Double Ignimbrite and unnamed sandstones from the same stratigraphic level exposed at Nonning (Allen et al., 2003  2008). In contrast to the pyroclastic origin of the Mount Double Ignimbrite, the Mount Friday Formation is entirely of (volcanogenic) sedimentary origin. The combined Mount Friday Formation and Mount Double Ignimbrite form an important stratigraphic marker horizon within the Upper Gawler Range Volcanics.

Re-instated as Murray Group discussed by Rogers, P.A.  "Discussion and Reply" (AJES 46, p485-486). Lithostratigraphy has now been overhauled and revised by Cowley and Barnett (2007) - see RefID: 64237 where a detailed nomenclatural history and evolution is presented. The Ludbrook (1961) strat.scheme included all units between base of Bookpurnong Beds (top) and top of Ettrick Formation (basal), namely, Mannum Fm., Finniss Clay, Morgan Limestone and Pata Limestone - with the basal Ettrick Fm being incorporated with Compton Conglomerate into the Glenelg Group which underlay the Mannum Fm (Murray Group). Lawrence (1969) then expanded the group to include all Tertiary marine units above the underlying Knight Group - namely, Netherby Marl, Geera Clay, Duddo Limestone and Winnambool Formation, as well as Bookpurnong Beds and Diapur Sandstone above; in 1975 Lawrence excluded the latter from a revised scheme. Another revision in 1988 removed Bookpurnong Beds from the Murray Group. Rogers (1995) then incorporated Mannum Formation, Morgan Limestone and Pata Limestone into one single unit, Mannum Limestone.  There then followed a comprehensive lithological and palaeontological study by Lukasik and James whereby Murray Group was elevated to Murray Supergroup (including Ettrick Fm., Geera Clay and Winnambool Fm. but not Duddo Limestone - with Mannum Fm, Finnis Fm. and Pata Fm. reinstated (as formations) but Morgan Limestone became Morgan Group. This became controversial and was met with resistance. The outcome of this debate is that Murray Supergroup has not been accepted and Murray Group has been reinstated, but the Morgan Group is retained at the subgroup level as Morgan Subgroup with the original members, namely, Woolpunda Marl, Portee Carbonate and Cowirra Clay Members.|Consolidated well bedded pale grey, yellow, white and cream, highly fossiliferous skeletal calcarenite, calcareous cemented quartz sandstone, bioclastic limestone; minor weakly consolidated calcareous clay; abundant skeletal debris.|carbonate sedimentary rock|siliciclastic sedimentary rock||N||17-JAN-23
