Geological Basin Structural Elements
dataset:
GEOL_BASIN_STRUCT_ELE
Executive summary:
As part of the Victorian Gas Program (VGP), the Geological Survey of Victoria (GSV) is studying the Otway Basin's petroleum
systems components (reservoir, seal and source), to assess its petroleum prospectivity and to estimate the potential for further
conventional gas discoveries onshore and offshore within Victoria's jurisdiction.
Reference to geological structural elements (e.g. the Penola Trough or Port Campbell Embayment) enable geologists to convey
ideas about geological features in specific locations. Throughout the VGP, geological structural elements such as troughs
or depocentres, platforms, basement and topographic highs have been referenced. As the studies progressed, it was evident
that a standard set of names and boundaries for structural elements in the Victorian Otway Basin needed to be defined.
New data and interpretations arising from VGP studies, such as the airborne gravity data (Carter et al., 2019) and the 3D
geological framework model (Romine et al., 2020), were used in this study to accurately define the boundaries of structural
elements. Existing interpretations and literature were also consulted and combined with the boundary definitions to develop
a set of georeferenced polygons or shapefiles, defining the major structural elements of the Victorian Otway Basin: Early
Cretaceous depocentres, Late Cretaceous depocentres and platforms, and basement and topographic highs.
From previous publications, consistent naming had been established for most structural elements; however, some elements had
multiple names. Most previously identified structural elements were ill-defined with only small-scale illustrations available.
The names used to define the structural elements in this study were resolved by considering the evolution of the understanding
of the Otway Basin, along with historical precedence and common usage in the literature.
This review of Victorian Otway Basin structural elements provides a detailed set of output files (Attachment A1). These can
be used as a consistent reference for future mapping and modelling studies. The structural elements defined in this study
are not considered a definitive list. Further refinements should be possible if new data is acquired over areas where data
availability limited the interpretation in this study.
