## **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.
RMS geomodelling was used to construct the geological model for the Hunter subregion. The data set contains the eroded horizons extracted from the completed geological model in ESRI grid format. The model was built using data extracted from well completions 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.
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:
Regional horizon name Age (geological stage) Newcastle Coalfield Hunter Coalfield Western Coalfield Central or Southern coalfields
M600 Top Anisian Top Hawkesbury Sandstone Top Hawkesbury Sandstone Top Hawkesbury Sandstone Base Wianamatta Group
M700 Top Olenekian Base Hawkesbury Sandstone Base Hawkesbury Sandstone Base Hawkesbury Sandstone Base Hawkesbury Sandstone

P100 Upper Wuchiapingian Base Newcastle Coal Measures Base Newcastle Coal Measures Top Watts Sandstone Top Bargo Claystone

with 'M' referring to Mesozoic and 'P' to Paleozoic
## **Purpose**
For display on HUN 2.12 geological figures (at the time of this metadata Figure 009)
## **Dataset History**
This model was then eroded using the present-day surface topography. The final eroded model has a horizontal resolution of 2000 x 2000 m (x y), with 109 vertical layers for a total of 511,118 cells. The depth ranges between 1185m above sea level and 5062 m below sea level.
Data originally sourced from 44 well completion reports and incorporated into the geological model. The final eroded model horizons were exported from RMS software as .dat files and converted to ESRI grids.
