The underlying geology is a gray shaly metamorphosed limestone, perhaps turbidite, interbedded with sandstone; sands and gravels fill the valleys.
Episodic growth of local fold structures is documented by significant changes in the thickness of turbidite systems.
The fieldwork is focussed on investigation of a wide range of remobilisation features in turbidite sequences.
The turbidite deposits have well-developed normal grading, evident from both visual observations in the field and from sieve analysis.
These mapping techniques have been applied to a Permian turbidite fan complex in the Tanqua Karoo Basin, South Africa.
