The Lamington National Park is located on the northern side of the [[Tweed volcano]]. This large [[shield volcano]] is over 100 kilometres in diameter, and extends from [[Tamborine Mountain]] in the north to [[Lismore, New South Wales|Lismore]] in the south. The volcanic plug of [[Mount Warning]] marks the centre of the volcano. This volcano was active around 23 million years ago<ref>Knesel K. M., Cohen B.E., Vasconcelos P. M., and Thiede D.S.

Both [[basaltic]] and [[rhyolitic]] lavas were erupted, and erosion of these lavas from rain and running water has formed the many spectacular landforms including cliffs, now observed in the park. Under these layers is a layer of [[tuff]] made from volcanic ash and fine rock which is up to {{convert|60|m|ft}} thick in some places.<ref name="lackner"/> The basalts of the Lamington Plateau originate from the Focal Point volcano.<ref name="tgoa">{{cite book |title=The Geology of Australia |last=Johnson |first=David |year=2009 |publisher=Cambridge University Press |isbn=978-0521767415 |page=196 |url=https://books.google.com/books?id=RSIbLENyT2wC |access-date=25 August 2014 |url-status=live |archive-url=https://web.archive.org/web/20180228095751/https://books.google.com/books?id=RSIbLENyT2wC |archive-date=28 February 2018  }}</ref> Near Binna Burra the maximum thickness of the basalt layer is estimated to be {{convert|700|m|ft}}.<ref name="naq"/>
