This information has been obtained from the report: Eruption Points of the Newer Volcanic Province of Victoria by Neville Rosengren. This report was published in 1994 and was prepared for the National Trust of Australia (Victoria) and the Geological Society of Australia (Victorian Division). The review of eruption points was based on an earlier unpublished manuscript Catalogue of the post-Miocene volcanoes of Victoria compiled by O P Singleton and E B Joyce (Geology Department, University of Melbourne 1970). |

Type 4: | Lava hill. | |
Melbourne Hill is an elongated lava mound with at least two points of eruption. Several lavas of differing composition were erupted. From the northern end a flow of limburgitic basalt has been partly covered by a later flow of olivine basalt. A radiometric date (K-Ar) or the lower lava gave an age of eruption of 4.21 (+/-) 0.05 million years ago. | ||

Regional: | The site is important for the variety of lava types rather than the morphology of the eruption point. | |
