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.\n\n\n\nThe dataset contains the ESRI grid versions of the reference horizons extracted from the structural 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 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 (DAT files from HUN RMS Output Dat Files v01 - c975d250-b699-4585-b32f-cbfde4d8d436) which draw information from the well completion reports (See data set: Hunter deep well completion reports - f2df86d5-6749-48c7-a445-d60067109f08 & South Sydney Deep Well Completion Reports V02 - 110bca9d-c0c1-49e9-888c-2b3a8ae706f7) used to build the RMS model.\n\n\n\nNine 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.\n\n\n\nThe 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:\n\n\n\nRegional horizon name \tAge (geological stage)\tNewcastle Coalfield\t                                Hunter Coalfield\t                    Western Coalfield\t                        Central or Southern coalfields \n\n\n\nM600\t                       Top Anisian\t                Top Hawkesbury Sandstone\t                Top Hawkesbury Sandstone\t    Top Hawkesbury Sandstone\tBase Wianamatta Group\n\nM700\t                       Top Olenekian\t                Base Hawkesbury Sandstone\t                Base Hawkesbury Sandstone\t    Base Hawkesbury Sandstone\tBase Hawkesbury Sandstone\n\nP000\t                       Top Changhsingian\t        Base Narrabeen Group\t                        Base Narrabeen Group\t            Base Narrabeen Group\t                Base Narrabeen Group\n\nP100\t                       Upper Wuchiapingian\tBase Newcastle Coal Measures\t        Base Newcastle Coal Measures   Top Watts Sandstone\t                Top Bargo Claystone\n\nP500\t                       Mid Capitanian\t                Base Tomago Coal Measures\t                Base Wittingham Coal Measures  Base Illawarra Coal Measures\tBase Illawarra Coal Measures\n\nP550\t                       Top Wordian\t                Base Mulbring Siltstone\t                        Base Mulbring Siltstone\t            Base Berry Siltstone\t                Base Berry Siltstone\n\nP600\t                       Mid Roadian\t                Base Maitland Group\t                        Base Maitland Group\t            Base Shoalhaven Group\t        Base Shoalhaven Group\n\nP700\t                       Upper Kungurian\t        Top Base Greta Coal Measures\t       Top Base Greta Coal Measures\t\t\n\nP900\t                       Base Serpukhovian\t        Base Seaham Formation\t                       Base Seaham Formation\t\t\n\n\n\nwith 'M' referring to Mesozoic and 'P' to Paleozoic\n\n\n\nCoordonate system: GDA_1994_MGA_Zone_56\n\n## **Purpose** \n\nThe grids were used in ArcGIS maps to show the  reference horizons for the RMS model.\n\n## **Dataset History** \n\nRMS geomodelling was used to construct the geological model for the Hunter subregion. The dataset contains the layers extracted from the completed geological model (DAT files) processed into ESRI grid format using ArcGIS. 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 (DAT files from HUN RMS Output Dat Files v01 - c975d250-b699-4585-b32f-cbfde4d8d436) which draw information from the well completion reports (See data set: Hunter deep well completion reports - f2df86d5-6749-48c7-a445-d60067109f08 & South Sydney Deep Well Completion Reports V02 - 110bca9d-c0c1-49e9-888c-2b3a8ae706f7) used to build the RMS model.\n\n\n\nThis 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.\n\n\n\nData originally sourced from 44 well completion reports and incorporated into the geological model. The reference horizons were exported from RMS software as .dat files and converted to ESRI grids.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (XXXX) HUN RMS Model Reference Horizons Grids V01.
