ABSTRACT The Waddikee Rocks are located on northern Eyre Peninsula. They are unusual because of their migmatitic composition. They are also associated with the fate of the early explorer of the region, J.C. Darke. The hills are upstanding because of the massive character of the country rock, by contrast with the gneiss that underlies the adjacent areas and which has been weathered to produce a ferruginised (possibly lateritic) regolith. The possible correlation of the latter and the laterite of the Gulfs region is discussed, as is its implication for the age of the Waddikee Rocks, for the age of duricrust can be extrapolated to indicate the likely age of the upland.

南澳大利亚艾尔半岛北部 Koongawa Waddikee Rocks 的推定前新生代年龄

摘要 Waddikee Rocks 位于艾尔半岛北部。由于它们的混合成分,它们是不寻常的。它们还与该地区早期探险家 JC Darke 的命运有关。由于乡村岩石的巨大特征,山丘是直立的,与位于相邻地区下方的片麻岩形成鲜明对比,片麻岩已经风化产生了铁锈化(可能是红土)风化层。讨论了后者与海湾地区红土的可能相关性,以及它对 Waddikee 岩石年龄的影响,因为可以外推硬壳层的年龄来表明高地的可能年龄。
