Compilation of geological and bore hole data from south-western Victoria and the contiguous part of South Australia with particular reference to the Portland - Nelson - Mt Gambier area

The area under review in this report comprises a large territory located in south-western Victoria and south-eastern South Australia. The scope of direct geological information in the areas underlain by marine Tertiary rocks is severely limited, by very poor exposure of the underlying rocks at the surface. Under such conditions, once the scattered exposures have been examined and recorded on the map, little more can be done by surface work; the geologist is thrown back on a study of well and bore records and of the results of geophysical measurements. Considerable literature has been read and records of the principal bores in the area have been examined in detail. It has been recommended that a geophysical survey of the area be conducted, to determine, if possible, any structural features which might exist at depth in this southern-most extension of the Murray River Artesian Basin, which is made up of Tertiary to Recent formations, resting, in the area under review, on a basement of Pre-Cambrian or Jurassic Rocks. This report comprises an overview of the general geology, geological history, stratigraphy and topography of the area under consideration. Geological, bore-hole and well data has been compiled and tabulated. A geological sketch map is included.
