Private land. Grazed and cropped, large planted windbreaks, outcrop in road cutting shows scoria and bombs. | ||
Type 9: | Composite lava and scoria volcano | |
Wheeler Hill is a large composite volcano being a well-defined scoria cone with a crater open towards the northwest and lava flows to the north contributing to the Deadmans lead at Daylesford. A small summit flow has been analysed as limburgite - a dense ultrabasic lava consisting of olivine and augite. Cuttings on Wheeler Hill Road expose pyroclastic deposits and lava bombs. | ||
791 m; 75 m. | ||
Regional: | This is a good example of limburgite which is an uncommon rock in the Newer Volcanics Province. This is also one of the few exposures of pyroclastic rock in the Central Highlands. | |
CLass 3: | The current agricultural land use is compatible with maintaining the geological and geomorphological values of the site. The site would be threatened by smaller farm development or subdivision. | |
