Abstract

During the period 1991-94 the Australian Geological Survey Organisation (AGSO) participated ina co-operative study of the early development of the Otway Basin as part of a National Geoscience Mapping Accord project. The other partners in the project were the Geological Survey of Victoria(GSV), the Department of Mines and Energy, South Australia (MESA), and the Victorian Institute of Earth and Planetary Sciences (V1EPS) at Monash and La Trobe Universities. As part of the project, four subsurface horizons were mapped at 1:250000 scale across the onshore parts of thebasin using exploration industry and AGSO seismic data. This is the first time such mapping has been undertaken on a basin-wide scale in the Otway Basin. MESA undertook mapping in the SouthAustralian sector of the basin, GSV in the central (western Victorian) part of the basin, and AGSO and V1EPS in the eastern part of the basin. This Record accompanies a folio of nine 1:250000 scale maps compiled by AGSO and V1EPS from the onshore eastern part of the basin centred on the Port Campbell Embayment, Colac Trough andOtway Ranges. Four of these maps are presented as two-way times (milliseconds) to four mega-sequence boundaries together with interpreted structural information. The four mega-sequenceboundaries are, 1) - base Wangerrip Group, 2) - top Eumeralla Formation, 3) - top Crayfish Group, and 4) - top Palaeozoic basement. Also included in this Record are four associated isoehron and seismic line information maps at 1:250 000 scale and geophysical maps (gravity and magnetic data)at 1:250 000 and 1:1000 000 scales. The maps are designed to improve the general uderstanding of subsurface basin geometry as a guide to possible hydrocarbon resources both onshore andoffshore.
