Abstract
In consequence of planning, by the South Australian Government, to develop and mine the coal seams it was considered that the outer limits of the seams should be known with reasonable accuracy so that neither railway lines nor other permanent structures should be built over coal-bearing ground. An accurate knowledge of these limits was desirable for another reason, namely that in the peripheral zone the ratio of overburden to coal was more favourable than elsewhere. At the request of the South Australian Director of Mines the Commonwealth Government agreed to carry out a routine survey of the periphery of the basin, following the completion of preliminary trial surveys. These were carried out between January and April, 1946. Magnet, earth resistivity and gravity methods were used, of which only the gravity methods proved useful. The history of the field, geophysical problem, gravity instruments, testing, and results are discussed in detail in this report. Accompanying geological plans are included.
