Abstract:

The Miocene Caversham Sandstone and Goodwood Limestone represent a 200m+ thick sheet of mixed terrigenous and bioclastic sand to silt grade marine sediments.
The Caversham facies is typified by steady sedimentation end life assemblages of outer shelf character. In contrast the Goodwood facies is typified by episodic sedimentation, featuring both hardground and channel fill sequences with death assemblages representing an inner shelf depositional environment.
South of Shag River Pleistocene terraces and raised beach deposits are unconformable on the marine sequence. These facies relationships may be explained by several episodes of eustatic sea-level fluctuations during an overall marine regression.
