A mesoproterozoic continental flood rhyolite province, the Gawler Ranges, Australia: the end member example of the Large Igneous Province clan.

The article discusses the mesoproterozoic continental flood rhyolite province, the Gawler Range Volcanics (GRV) in South Australia. It presents a viable mechanism for sustaining a large volume felsic igneous province and suggests that the GRV province represents an end member of the Large Igneous Province clan. It notes that the low viscosity of the felsic magmas has produced a unique igneous system on a scale which is either not present or poorly preserved elsewhere on the planet.
