Lake-filled Tower Hill maar is part of the voluminous Newer Volcanics Province, which covers a broad 15,000 km2 area of SE Australia. The volcanic field contains nearly 400 vents, with late-Pleistocene to Holocene eruptions producing scoria cones, maars, tuff rings, and valley-filling lava flows. The most recent eruptions took place at Mount Schank and Mount Gambier.

Sintesi geologica

The voluminous Newer Volcanics Province covers a broad 15,000 km2 area of SE Australia with nearly 400 small shield volcanoes and explosive vents of Tertiary-to-Holocene age. Volumetrically the vast proportion of volcanic products consist of flat-lying lava flows, although the most prominent features of the volcanic field are the numerous small scoria cones, tuff rings, and maars that rise above the lava plain. Several vents were active during the Holocene; another vent (Mount Tower) is now considered to be of late-Pleistocene age. Late-Pleistocene to Holocene eruptions are characterized by small volume and low explosivity. The youngest dated eruptions took place at Mount Schank and Mount Gambier about 5,000 years ago, when explosive activity formed several maars and associated lava flows.
