Field Notes

This field guide covers four sites in the vincinity of Bells Line of Road from Richmond to Kurrajong Heights. This field trip is suitable for a family, a school class or a youth group and would take about 3–4 hours to complete. This field trip will help you 1. know how to read geological maps; 2. understand how geologists work; 3. learn some common geological terms; 4. understand how to work out a geological cross-section; 5. understand how to work out a geological history of an area.
Geological Histories

The Brisbane area is a very interesting area because there is a large variety of different rocks exposed and these can be inspected without a lot of travel. The geological formations exposed in the Brisbane area extend for many hundreds of kilometres, covering other states of Australia. Thus, a knowledge of the local geology of an area has a much wider application beyond that area.

The oldest rocks in the Carnarvon Gorge area occur at considerable depth and are only known from drilling and geophysical investigations. However, it is likely that the deepest rocks are related to the exposed fold belts of eastern Australia. These were deposited rapidly early during the global Flood. |
