The dataset was derived by the Bioregional Assessment Programme from the Hunter RMS geological model. You can find a link to the parent dataset in the Lineage Field in this metadata statement. The History Field in this metadata statement describes how this dataset was derived.


The data set contains the ESRI grid versions of the depth structure exported from the folded and eroded RMS geological model for the Hunter subregion. RMS geomodelling was used to construct the geological model for the Hunter subregion. The model was built using data extracted from well completion reports published by mining companies and consultants which record the depth of various formations encountered during drilling works. These data were compiled into model input files (See data set: Hunter deep well completion reports - f2df86d5-6749-48c7-a445-d60067109f08) used to build the RMS model.


Nine geological formations and their depths from the surface are included covering a grid across the Basin. The geological model is based on measured depths recorded in Well completion reports published by mining companies and consultancies.


The naming convention refers to the geological age and depth (TVD ss = total vertical depth subsea reported to the Australian Height Datum) of the various formations as follows:

## **Purpose** 

The grids were used in ArcGIS maps to show the depth structure for the RMS model.

## **Dataset History** 

The data set contains the ESRI grids exported from the Hunter RMS geological model. There is a separate image for the legend. The grids were used in ArcGIS to show the depth structure for the RMS model. Depth values were recorded in the well completion reports for the Hunter subregion, then compiled into text files and surfaces built in the RMS model.
