Editing Minerva Hills National Park (section)

== Geology ==
The Minerva Hills National Park sits on the [[Oligocene]] Minerva Hills Volcanics. These volcanics have been broadly divided into a basal series of [[Mafic|mafic lavas]] (some 70 m thick) overlain by a series of intercalated mafic volcanics, felsic volcanics ranging from [[trachyte]] to [[rhyolite]] and trachytic [[Pyroclastic rock|pyroclastics]].  The pyroclastics are related to plugs and domes. The lower sequence has been dated at approximately 33 -34 Ma (million years) and the upper sequence 28.5–27.5 Ma.<ref>{{Cite journal|last=Ewart|first=A.|date=1981-11-10|title=The mineralogy and chemistry of the anorogenic tertiary silicic volcanics of S.E.

The Minerva Hills Volcanics is a remnant of Oligocene [[Hotspot (geology)|hot spot]] volcanism known as the Cosgrove Hot Spot. This hot spot forms the longest continental hot spot track on earth.<ref>{{Cite journal|last1=Hansma|first1=Jeroen|last2=Tohver|first2=Eric|date=2019-06-13|title=Paleomagnetism of Oligocene Hot Spot Volcanics in Central Queensland, Australia|url=https://www.researchgate.net/publication/333781244|journal=Journal of Geophysical Research: Solid Earth|volume=124|issue=7 |pages=6280–6296 |doi=10.1029/2019JB017639|s2cid=197566315 }}</ref>
