Drilling has detected sand of early Tertiary age overlain by younger loam, kunkar and clay. The sand is lying unconformably on weathered Precambrian bedrock or on Permian glacial clay. Drilling on Section 140, Hundred Willunga has failed to locate a...

Two unsuccessful bores on the property of K.L. Blythman, Hundred of Willunga Section 596, and, one successful bore for L.L. Moritz, Hundred of Willunga, Section 8 were examined. Water was obtained in Moritz. Bore in the North Maslin Sands about 120...

Boring has proved 1½ million cubic yards of basal Tertiary sand under 600,000 cubic yards of overburden to an average depth of 12 feet. The sands lie on an uneven basement of Permian and Proterozoic sediment which shallows to the north. The sand has a...

Thirty eight samples collected during a soil survey of the Hundreds of Noarlunga and Willunga belong to Tertiary formations ranging in age from Eocene to Pliocene and to Quaternary clays, sands and gritty sand. A bore on private property on Section...

Croydon Bore no. 2 was drilled during 1892-93 to a total depth of 2296 feet, and penetrated a sedimentary sequence of Tertiary rocks to 2035 feet before bottoming in sediments believed to be Permian glacigenes. Pleistocene to Recent sandy clays and...

Further boring has confirmed the presence of 2½ million cubic yards of sand covered by 2 million cubic yards of overburden. The mean clay content of all samples tested from section 142 is 7.6% by weight. Unwashed sand has a slightly higher proportion...

A programme of auger drilling was devised to test an area of Maslin Beach to prove sand suitable for general concrete aggregate. Reserves of sand in the area drilled are estimated to be 700,000 cubic yards. Overburden accounts to 200,000 cubic...

Boring has proved a maximum thickness of 32 feet of Upper Tertiary sand underlain by Port Willunga Beds. These vari-coloured sands which are too fine for use as concrete fine aggregate require washing to conform to standard specifications. Although...

Boring has intersected basal Tertiary North Maslin Sands under Tortachilla Limestone. The age of the underlying clays is tentatively regarded as Permian. An estimated 60 000 cubic yards of overburden covers 220 000 cubic yards of sand within the...

Microfloras from Eocene marine and non-marine sediments, intersected in two deep bores in the Adelaide Plains Basin, can be placed within two distinct assemblage units. The correlative value of these as time-stratigraphic units is discussed.

Three relatively deep bores, drilled recently on the northern Adelaide Plains in the Hundred of Port Gawler, about 20 miles north of Adelaide, have intersected useful complementary sections of the Cainozoic succession, ranging from 560 feet to 1148...

Reconnaissance sampling of coastal and inland exposures of the Tertiary succession in the Willunga and Noarlunga sub-basins of the Saint Vincent Basin indicates that the P205 content of the sediments is below the average of normal marine carbonates. A...

Auger drilling has been undertaken on behalf of Monier Besser Pty Ltd on section 364, Hundred of Willunga, to determine the availability of sand suitable for the manufacture of roof tiles. The property adjoins the Main South Road near Pedlar Creek,...

The area tested contains sands of Tertiary age overlain by a thin veneer of Recent material. The probable reserves within this area are a quarter million cubic yards; the possible reserves are three-quarter million cubic yards. The sands are finer...

The North Maslin sand of Miocene age forms the base of the coastal Tertiary section of the Willunga Basin about 26 miles south of Adelaide. This sand is exposed in the Maslin Bay quarry where it is suitable for concrete fine aggregate. Recently it has...
