Mount Quincan, Volcanic summit near Yungaburra, Australia

Mount Quincan is an extinct cinder cone near Yungaburra on the Atherton Tableland in Far North Queensland. Its crater is about 500 m across, with the main cone to the northwest, and the summit stands 862 m above sea level, roughly 159 m above the surrounding terrain.

This mountain was formed through volcanic activity, and deposits within its crater have been scientifically dated to approximately 7,250 years ago. These findings help researchers understand the environmental history and changes that occurred in northeast Queensland.

The mountain belongs to the Atherton Tableland region, where geological studies of its deposits contribute to understanding prehistoric ecological conditions in northeast Queensland.

Mount Quincan lies about 11 km east of Atherton and close to Yungaburra, reached from the Tablelands road network. Quincan scoria is quarried from the southwest quadrant of the mountain, so that side carries extraction workings rather than walking country. The crater rim is roughly 500 m across, with the main cone to the northwest.

The scoria mined from the mountain's southwest quadrant is a local building and garden material called quincan, and the name of the mountain comes from it. The same deposits carry abundant mantle xenoliths of peridotite, rock torn from below and brought up by the eruption.
