Usage: Briefly described (p5, p6.) Comments: Re-named the Eumeralla Formation by VandenBerg et al. (2006) and VandenBerg (2008); it has identical mineralogical and radiometric RGB image characteristics across southern Victoria. Because of its entrenched use in the petroleum industry, the Wonthaggi Formation name is retained for Eumeralla Formation-equivalent rocks in the Gippsland Basin. , Is overlain unconformably by the Thorpdale and Neerim Volcanic Groups.
