1-ACEG Walking Tour
Walking tour of Brisbane Geology
This half day walking tour of Brisbane City will explore the two principle geological units within which much of the Brisbane is constructed. Lunch will be provided as part of the tour fee.
The Neranleigh Fernvale beds underlie much of the Brisbane CBD and therefore form the bedrock to almost all the high-rise development we see today. During the walk we will discuss how the geological history of these rocks has impacted the engineering of the city buildings.
The Brisbane tuff will be examined during the walk along the Kangaroo Point cliffs and perhaps some cliffs on the north side of the river toward New Farm. These cliffs preserve more than 20 metres of hard rock which was used extensively as a building stone for much of Brisbane’s history. Its impact on the development of Brisbane will be discussed on the walk.
As we will be walking beside the Brisbane River, we will also comment on the effects of the river on the city’s development. We can also observe some recent sediments and discuss how we as geologists use these deposits to interpret older depositional settings.
