A geological model based on a plain reading of the Bible suggests that geological processes acting in the past varied in nature and intensity from time to time. Consequently, characteristics such as the physical scale of a rock unit, its degree of disturbance, how the unit responds to disturbance, its texture and fossil content will help classify the rocks within a biblical framework. This concept has been applied to the basement rocks of the Brisbane area, Australia. Following a process of elimination, it is concluded that the basement rocks were deposited early during the Flood event, that is the Eruptive phase as defined by Walker’s biblical geologic model.


One of the important tasks facing Creationists is to relate geological data within a biblical framework. Geological data is interpreted and presented in terms of evolutionary framework. As a result, when a person inspects a geological map or reads a geological text-book it is not obvious how the data could possibly relate to biblical history.

In 1994 Walker1 presented a geologic model based on the Bible at the third International Conference on Creationism in Pittsburgh, Pennsylvania. The model provides a framework to interpret the geology of an area in terms of a biblical understanding. A number of criteria were suggested by which rocks can be classified. Froede has independently proposed the same concept, that creationists use a geological framework based on the Bible, but has not developed the idea to where it can be used for classification purposes.2

This paper examines the basement rocks in the Brisbane area, Australia to see if they can be classified within the framework of Walker’s biblical geologic model.

Relationship between the Bible and geology

The purpose of a biblical geologic model is to successfully link two different sources of information, namely, written biblical history and observed geological data. Whenever different sources of information are encountered, such as field notes and map information, they need to be related together. Unless this is done neither source will be of assistance to the other. Map information, for instance, provides no assistance to navigation until a location on the map can be tied to a physical location on the ground….
