Otway Basin: Regional Seismic Horizon Maps for the Onshore Areas at the 1:500 000

During the period 1991-94, a co-operative study of the early development of the Otway' Basin was

undertaken as part of a National Geoscience Mapping Accord project. The partners in the project

were the Australian Geological Survey Organisation (AGSO), the Geological Survey of Victoria

(GSV), the Department of Mines and Energy, South Australia (MESA), and the Victorian Institute

of Earth and Planetary Sciences (VIEPS) at Monash and La Trobe Universities. As part of the

project, four subsurface horizons were mapped across the onshore parts of the basin using

exploration industry and AGSO seismic data. MESA undertook mapping in the South Australian

sector of the basin, GSV in the central (western Victorian) part of the basin, and AGSO and VIEPS

in the eastern part of the basin. This is the first time such mapping has been published on a basinwide

scale in the Otway Basin.


This Record accompanies a folio of ten 1:500 000 scale maps compiled by AGSO from the data

provided by NGMA partners from the western, central and eastern parts of the onshore basin. Four

of these maps are presented as two-way times (in milliseconds) to four mega-sequence boundaries

together with interpreted structural information. The four mega-sequence boundaries are: -

1) - base Wangerrip Group,

2) - top Eumeralla Formation,

3) - top Crayfish Group,

and 4) - top Palaeozoic basement.


Time thickness (isochron) maps (in milliseconds two-way time) for the Crayfish Group, the

Eumeralla Formation and the Sherbrook Group, complete the horizon mapping. Also included are

maps of seismic line information and tectonic elements, and geophysical maps of gravity and

magnetic data. The maps are designed to improve the overall understanding of Otway Basin

subsurface geometry and tectonic evolution as a guide to possible hydrocarbon resources.
