Following investigations at Oliver's phosphate workings, Sections 65 and 66, Hd. Willunga (Callen, 1968), it was decided to map Wait's workings on Section 40, Hd. Noarlunga and those on Section 48 at the same stratigraphic horizon. Reconnaissance...

Diapiric marbles and dolomitic siltstone breccia of presumed Willouran age intrude younger Umberatana Group rocks which have been folded into an elongate domal structure and, in part, rest unconformably on the diapiric core. Within the diapir several...

Mapping of the Winnininnie 1:63,360 mapsheet has been undertaken as part of a programme to complete mapping of the Olary 1:250,000 Sheet. The area lies about 200 miles from Adelaide on the road and railway line to Broken Hill, and includes the...

Large sedimentary phosphorate deposits are unlikely to be found in the Cambrian on Fleurieu Peninsula or the southern part of Yorke Peninsula. Further exploration of the phosphatic Brighton Limestone and Saddleworth Formation type of facies should be...

This investigation was a feasibility study, therefore environmental factors are dealt with in much more detail than would be necessary in a routine geochemical report. Apparently these factors has little significant effect on the results. Spot...

A programme of stratigraphic section measurement is envisaged in order to facilitate rock correlation and help outline the pattern of sedimentation in the Adelaide Geosyncline. In many areas measurement may be made on air photo enlargement, as has...

A deposit of bedded phosphate rock occurs in a siltstone unit 40-50 feet thick within an essentially calcareous sequence 25 miles south of Adelaide. Approximately 8,000 tons of phosphate rock were removed in the period 1907 to 1930. There are possible...

The Parachilna 1:250 000 map area is about 250 road miles north of Adelaide, South Australia, and includes the eastern shore of Lake Torrens, the central Flinders Ranges and part of the Lake Frome Plains. The ranges are composed of folded Adelaidean...

Despite the palaeoecological emphasis of most recent stromatolite research outside the USSR, controversy still exists regarding the environmental restriction of these organosedimentary structures and in some cases, analogies with modern occurrences...

Includes an outline of the Adelaidean stratigraphy, and the underlying igneous and metamorphic rock types, and brief, mainly historical review of the economic geology.

Phosphatized oolitic limestone and sandstone occur within arenaceous carbonates at the top of the Tapley Hill Formation, at or near the Brighton Limestone contact on the Fleurieu Peninsula and in similar stratigraphic, sedimentary setting between...

Stratigraphic sections were measured in the Brighton Limestone and part of the upper transitional beds of the Tapley Hill Formation in quarries and natural outcrops at Brighton, Hallett Cove, Reynella, Noarlunga, Myponga, Orroroo and Tarcowie. Flat...

Pronounced positive and negative geophysical anomalies on EVERARD represent the crystalline Musgrave Block in the north, a basement trough more than 4 km in depth that flanks the Musgrave Block to the south, and the crystalline Ammaroodinna Inlier to...

History The results of previous work carried out on the Tapley Hill Formation shale showed that, while a light weight aggregate could be produced from it, the narrow bloating range made processing difficult, owing to agglomeration of the material in...
