In the Triassic coal measures of Telford Basin occurring 1000 + (?) feet stratigraphically above the main (Telfod) seam are a number of coal seams - the "Upper coal series" - which further add to the opencut coal reserves at Leigh Creek Coalfield....

The area under review is situated in the south-eastern section of Telford Basin between co-ordinates 8,000 and 34,000, and is a southern extension of the main (Telford) coal seam proved previously on the eastern margin. Coal has been proved by close...

The Telford Basin is an asymmetrically shaped synclinal basin containing sediments of upper Triassic-Jurassic age, which cover a 25 square km area. Sub-bituminous coal occurs in three major series of seams which are informally termed the Leigh Creek...

Existing drill hole data (1100 holes) is unsuitable for interpreting the geological sequences for hydrological modelling or basin studies unless geophysically logged (114 holes). A proposed interpretation of gamma and neutron logs uses numeric cut -...

Palynological analysis was undertaken on two coal samples and a shale sample from within and just above the Lower Series Coal Seams of the Telford Basin, Leigh Creek.- The lowermost coal was dominated by monolete spores and the upper coal by...

Borehole drilled in 1952 to 247.8 metres in centre of the Telford Coal Basin intersected gently infolded sediments of Rhaetian (latest Triassic) to Bajocian (Middle Jurassic) which overlie the coal measures of Carnian (Late Triassic) age. Surficial...

Attempts have been made previously to correlate coal seams and interpret depositional environments and tectonics relative to the four Triassic coal deposits at Leigh Creek (Parkin 1953; Taylor 1954; Johns 1970, 1975; Johns and Townsend 1975). This...

A data review undertaken by MESA to assess the prospectivity of the northern Flinders Ranges intramontane basins for concealed Triassic coal, highlighted four main areas as having the best potential for a discovery. Of these, the alluvium-covered...

In 1993 an exploration drilling program was undertaken jointly by The Department of Mines and Energy (MESA) and ETSA Corporation (ETSA) over areas considered prospective for coal within the vicinity of the existing infrastructure of the Leigh Creek...

An airborne TEM survey, followed by ground magnetics and geochemical sampling, defined two areas in the vicinity of Lyndhurst considered to be prospective for supergene enriched copper oxide/sulphide mineralisation hosted within Neoproterozoic rocks...

Coal reserves in Copley (Lobe A), Telford (Lobe B) and at Northfield (Lobe C and D) in terms of previous drilling and mining operations. Discusses sediments, thickness and quality characteristics of seams. Proven, indicated and inferred reserves and...

The COPLEY 1:250 000 map area includes the northern Flinders Ranges and the southern part of the Willouran Ranges. It is bounded to the west by the Lake Torrens Sunkland and, to the east, by the Lake Frome Plains. A thick sequence of older Precambrian...

Four selected drill cuttings samples spanning a 12-metre depth interval within BHP Minerals' BR 97001 drillhole, located 26 km west of Lyndhurst, have been palynologically analysed and dated. Their contained palynoflora are correlative with the...

Three scout holes totalling 1245 feet were rotary drilled in Lobe B of the Leigh Creek Coalfield to test for any subsurface extension to a previously identified radioactively anomalous surface area. Although the Late Triassic clastic sediments...
