Hallett Cove is one of South Australia’s foremost natural science treasures. Exposed examples for prime geological concepts of superposition of strata, depositional unconformities (representing time breaks), and folding and faulting of sedimentary...

Shallow Precambrian crystalline basement underlies the greater part of the BARTON 1:250 000 map area. Thicker Neoproterozoic, Cambrian and Carboniferous Permian sediments occur in the northwest, with the southern margin bounded by the Karari Fault...

The OOLDEA 1:250 000 map area, in the far west of SA, includes portions of the Maralinga Tjarutja Aboriginal Lands, Maralinga Prohibited Area, and Nullarbor Regional Reserve. It is traversed by the Trans-Australian Railway. There is no significant...

Palaeoclimate is discussed, particularly in the central and southern parts of the continent, based on an overview of wide range of data. The oceanic record has provided the means for obtaining a refined chronological framework in which to place events...

Exploration for possible marine placer heavy mineral sands deposits within Recent sediments laid down across a large part of east-central Kangaroo Island, due south of Kingscote, has comprised a literature survey, limited field geological...

An area centred ~65 km north-east of Hawker in the Central Flinders Ranges, and located adjacent to the eastern side of the Oraparinna Diapir, has been explored for possible buried economic epigenetic copper, gold and uranium mineralisation. During...

Since the first edition of this map was released in May 2007, the collection by the Department's Geological Survey of much new geoscientific data and interpretations arising from South Australian regional surveys and exploration activities has...

Exploration for a range of mineral commodities over relinquished parts of a licence area situated 80 km north-east of Orroroo has mainly targeted the Cainozoic to Mesozoic cover rocks for possible sedimentary gold, uranium, mineral sands and...

An extensive area of Tertiary Lake Eyre Basin and Mesozoic Eromanga Basin sediments lying immediately to the north of the uranium-rich Mount Babbage and Mount Painter inliers is being explored for possible economic roll-front style palaeochannel...

During 2005, consultant geomorphologist Richard Russell was contracted by FDL to undertake a study of existing 'unsourced’ kimberlite indicator mineral (KIM) anomalies that occur in the northern part of the Springfield Project area. The initial aim of...

In the reporting period to 30th June 1995 for Exploration Licence 1944, Heathgate Pty Ltd completed no fieldwork, however geological evaluation work was undertaken. This work consisted of laboratory testing of drill core from a 1991 drilling program...

A small area located on the southern Lake Torrens Plains immediately west of the ABC Range was taken up to allow evaluation of its potential for having buried economic sedimentary coal and/or uranium mineralisation occurrences. There are no...

During the 2008-2009 licence year, most of the new work done consisted of appraisal rotary mud drilling at Four Mile East (112 holes for 24,460 m) and Four Mile West (113 holes for 19,120 m), with the addition of one NQ diamond cored hole (AKC093) for...

Work undertaken on EL 4378 during the 2009-2010 reporting year included the drilling of 478 vertical rotary mud holes totalling 132,960 m, and core drilling totalling 4117 m performed in 16 of these holes for stratigraphic unit / resource...

Digging of exploratory shallow costeans into lithified Tertiary arenaceous sedimentary units on the eastern bank of the River Murray, 2 km south-west of Taylorville, to search for inferred workable deposits of decorative fossiliferous sandstone, did...

Hallett Cove is one of South Australia’s foremost natural science treasures. Exposed examples for prime geological concepts of superposition of strata, depositional unconformities (representing time breaks), and folding and faulting of sedimentary...

During the period 1745–1700 Ma, felsic and mafic rocks were intruded throughout the Gawler Craton, broadly coeval with the 1740–1690 Ma Kimban Orogeny. These rocks were previously considered part of the Lincoln Complex, a stratigraphic term defined by...

Drill core samples from Polda 2,9,13 indicate Eocene and Pliocene ages.

The Cenozoic Eucla Basin is located on the southern margin of the Australian continent, with a present-day basin onshore edge which extends for over 2,000 km from Western Australia into South Australia. The basin’s sediment fill comprises a thin...
