GSV Report 61 - The Stradbroke Coalfield

| |||||
Product description:Abstract Uplift of the Strzelecki Ranges during the Tertiary resulted in the elevation of associated structures such as the Loy Yang Dome, the Baragwaneth Anticline and other structural units; as a consequence thick brown coal deposits in the overlying Tertiary sediments are now located at economically recoverable depths. A program to investigate structures along the eastern margin of the Strzelecki's and to explore for additional deposits was initiated in 1974. This was successful in delineating a reserve of 700 million tonnes of brown coal; the resource potential of the occurrence, called the Stradbroke Coal Field, is of the order of 1470 million tonnes. The field lies on a separate structural unit referred to as the Stradbroke Block. The brown coal is stratigraphically equivalent to the Eocene, Traralgon Seam of the Latrobe Valley, but has a lower moisture content than most of the coals found there; however, the sulphur content is somewhat higher. This may be due to the influence of the marine transgression which resulted in the deposition of Oligocene to early Miocene sediments over the partly eroded coal-bearing sediments in the eastern part of the Stradbroke Block.
