Uranium ore-forming systems of the Lake Frome regionLocality 1 (343230E ; 6643250N) - Arkaroola Homestead “Helicopter Pad” —A boudinaged section of the Opaminda Formation (calcsilicate) can be seen in the wall of a cutpad approximately 100m south of the Arkaroola Homestead. The Adelaidean sequence here,and in most other parts of the Flinders Ranges, shows very little evidence of metamorphismassociated with the Delamerian Orogeny (~490 Ma). The Opaminda Formation overlays theBlue Mine Conglomerate and is overlain by the Wortupa Quartzite which has a transitional andconformable contact.The boudinaged section, with subsequent faulting, may be a result of the Delamerian Orogenyor due to subsequent movement of the nearby Paralana Fault. Metamorphic grade is uppergreenshist facies.Page 125 of 151
Uranium ore-forming systems of the Lake Frome regionLocality 2 (340250E ; 6645550N) - Wywyana Creek to the east of the villageImmediately east of Arkaroola Village (approx. 100m) where the main road crosses WywyanaCreek, is another exposure of the Opaminda Formation at the base of Griselda Hill (named afterGriselda Sprigg, wife of Reg Sprigg, founder of the Arkaroola Tourist Resort).Here again the low grade metamorphism (greenshist facies) of the Opaminda Formation isevident.Page 126 of 151
