Australia: The Land Where Time Began

A biography of the Australian continent 

Glass House Mountains

Comprising 13 volcanic peaks in the Sunshine Coast hinterland. 4 of the peaks, Beerwah, Tibrogargan, Ngungun and Coonowrin are protected by separate national parks.

The Glass House Mountains are the lava plugs that remain after the volcano which formed them has eroded away. The volcano that formed them occurred as the continent passed over a hot spot that punched its way through the crust at this point.

A series of domes and peaks, of trachytic material, each of which represents an eruption centre that dates to 28-24 Ma.
