A summary of the geology, seismicity, geomorphology, and hydrogeology of the Okavango Delta, by D. G. Hutchins, L. G. Hutton, S. M. Hutton, C.R. Jones and E. P. Loenhert (1976)

The bulletin summarises what is known of the solid geology in the region surrounding the delta and inference is made from geophysical investigations on the extension of the different bedrock units under swamps. The structure, seismicity and geomorphology are elucidated from the results of remote-sensing surveys, and there is a summary of the limited information available on the hydrogeology and water chemistry of the delta.
