BackgroundThe voluminous Newer Volcanics province covers a broad 15,000 sq km 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, forming a series of scoria cones, maars, tuff rings, and major valley filling lava flows. The youngest dated eruptions took place at Mount Schank and Mount Gambier about 5000 years ago, when explosive activity formed several maars and associated lava flows.
