Likely excavation conditions during the proposed deepening of the boat channel at St. Kilda were investigated by drilling and seismic refraction surveys. Results showed 2 to 3 m of St. Kilda Formation (loose shelly sand) overlying up to 0.2 m of...

Interprets Bridge Oil / Target Exploration seismic data and shipborne magnetic data.

At the request of the Highways Department, a shallow refraction seismic survey was carried out near Delamere to test the rippability of the material to be removed. The material to be excavated consists of marble with varying degrees of fracturing due...

During September-December 1976, Murnaroo 1 was drilled by the SA Department of Mines to TD 627.5 m near Observatory Hill in the central southern part of the Officer Basin, to investigate the local subsurface stratigraphy and economic potential, and...

Survey between Nectar Brook reservoir and Redcliff Point over the proposed Redcliff petrochemical plant indicates that a narrow valley, filled with up to 200 metres of low density sediments, occurs beneath the western portion of the site. Subsidence...

Results of a seismic refraction and gravity survey conducted in the southern portion of the Walloway Basin suggest that its western margin is influenced by faulting. The survey has also indicated the position of a fault which controls groundwater...

Gravity data from a new major helicopter gravity survey and aeromagnetic and seismic data from TALLARINGA and adjoining map sheets is interpreted. The view that the positive gravity anomaly in the Tallaringa Trough is due to dense dolomitic rocks is...

The Duntroon Basin is an ESE-trending Mesozoic to Tertiary sedimentary embayment in the continental shelf, located SE of the Great Australian Bight Basin and west of Kangaroo Island. The report includes a discussion of the stratigraphy based on...

This report is based on groundwater data and description of the Seaford stratigraphic bore. Basement high was delineated by drill hole logs and seismic results.

27 shallow refraction spreads, totalling 2835 metres of traverse, were part of the feasibility study. Principal objectives were to confirm depth of soil / completely weathered rock, provide an indication of excavation conditions and detect geological...

Known and inferred geological characteristics and age relationships of the rocks infilling the wholly deeply buried Palaeozoic Warburton Basin are described. Depositional, structural and alteration aspects of the rocks are also mentioned, as they may...

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...

Edeowie 1 (TD 984 metres), which aimed to identify a series of seismic reflectors mapped by SADME beneath the eastern Lake Torrens piedmont plain, has intersected a stratigraphic sequence with features indicating that complex structural changes occur...

In the construction of marina, the results suggest that, apart from small areas, blasting should not be required if the material to be excavated is similar to that removed for the deepening of the cove at Cape Jervis.

Investigates rippability of near surface material at edge of the South Para Reservoir, and along proposed channel joining South Para and Warren reservoirs. 13 shallow drill holes are recommended.

An interpretation of all seismic data in SA part of the Otway Basin is part of a joint geological and geophysical study with the Victorian and Tasmanian Department of Mines and the BMR to produce a basin - wide interpretation. The geometry and...

Geophysical surveys at the City Council Depot site, delineated the extent of large depression, used as rubbish dump. Abrupt lateral terminations of volcanic ash and tuff sequence were correlated with the boundary of the depression. No solution...

A high resolution seismic reflection survey was completed by SADME on the SW margin of the Great Artesian Basin near Lake Eyre South. 38.9 line km of data was recorded from 17.9.85 to 14.12.85. Geophysical Service Inc. (Adelaide) were contracted for...
