Contains a description of the biostratigraphic determinations made on drill cuttings samples recovered from below 1047 feet depth in the subject drillhole. Metamorphic basement rocks were encountered at 1191 feet depth, and drilling ceased at 1260...

From 850 to 1020 feet depth the boring has continued in Eocene carbonaceous silty sands and clays of the Knight Group. The sands in this interval are less uniform in grain size than those above 835 feet, and are markedly coarser below 995 feet....

The stratigraphic succession from the surface to 600 feet depth in Pinnaroo bore is: - Pleistocene to Recent terrestrial sands and clayey sands, thickness 34 feet; - Loxton Sands (Cheltenhamian - Upper Miocene), thickness 107 feet; - ?continental...

The interpreted stratigraphic succession is as follows: 0-61 feet: terrestrial sands (Pleistocene-Recent); 61-180 feet: yellow-brown sands, clayey sands and grits (Loxton Sands, Upper Miocene); 180-195 feet: light grey-buff sands (? continental ?...
