Richmond river basin 3D geological model layers

Abstract

The dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.

These layers are the binding surfaces (= formation tops or interfaces between different stratigraphic units). These form the basis for the development of the volumetric three-dimensional geological model.

Dataset History

These layers are the binding surfaces (= formation tops or interfaces between different stratigraphic units). These form the basis for the development of the volumetric three-dimensional geological model. The workflow for the model development is described in detail in Clarence-Moreton bioregional assessment product 2.1-2.2 (Raiber et al., 2016).

The source for the binding surfaces are all geological data and digital elevation models.

These include:

Shuttle Radar Topography Mission (SRTM) digital elevation model

Coal seam gas, petroleum and stratigraphic wells

Groundwater bores

Shapefiles of the extent of different stratigraphic units

A table of revised formation tops provided by Metgasco Limited

Grids of key formation tops (Richmond coal seams, Kangaroo Creek Sandstone, Gatton Sandstone and Koukandowie Formation) provided by Metgasco Limited

Grids of formation tops provided by the NSW Department of Trade and Investment for stratigraphic units including the Walloon Coal Measures, Koukandowie Formation and other deeper layers.

From these data sources, the 3D geological model was developed in GoCAD and SKUA (Paradigm

Prior to use, all data were subjected to considerable data quality check. Interfaces such as those between the alluvium and the underlying volcanic or sedimentary bedrock are based primarily on data from groundwater bores. The data cleaning process and the steps involved in creating these interfaces is described in detail in Clarence-Moreton bioregional assessment product 2.1-2.2 (Raiber et al., 2016).
