Oonah formation

WebThe Arthur Lineament of northwestern Tasmania is a Cambrian (510 10 Ma) high-strain metamorphic belt. In the south it is composed of metasedimentary and mafic meta-igneous lithologies of the 'eastern' Ahrberg Group, Bowry Formation and a high-strain part of the Oonah Formation. Regionally, the lineament separates the Rocky Cape Group … WebThe Oonah Formation in the Zeehan-RenisonBell area is overlain, apparently conformably,by a maximum of 10,000 feet of unfossiliferous-purple and green mudstone, greywacke and slate of the Crimson Creek Formation (Blissett and Gulline, 1961a after Taylor, 1954). This passes upwards into the fossiliferous Dundas'-Group, which ranges in
