Richmond River basin GW bores stratigraphy

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.

This datsets contains inferred stratigraphy logs from groundwater bores in the Clarence-Moreton bioregion in NSW. In the original groundwater database, only very few stratigraphic records existed.

Dataset History

This datsets contains inferred stratigraphy logs from groundwater bores in the Clarence-Moreton bioregion in NSW. In the original groundwater database, only very few stratigraphic records existed.

To compensate for this lack of stratigraphic data, an attempt was made to convert lithological logs into stratigraphic logs. This was done in an iterative process, whereby the lithological logs were imported into a 3D geological modelling software, and then gradually the stratigraphy was inferred from the lithologcial logs.

The detailed method is described in Raiber et al. (2016). It is important to note that despite our best efforts to derive stratigraphic logs for all bores, there continues to be considerable uncertainty due to the poor quality of lithological data.
