HUN Geological Model Eroded Horizons Masks v01

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 shapefiles (MGA94 coordinates) are masks used to constrain the extent of interpolations for the various horizons in the RMS geological model. The masks define where the formations outcrop on the surface and thus define the eroded surface in the current topography. 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

P000 Top Changhsingian Base Narrabeen Group Base Narrabeen Group Base Narrabeen Group Base Narrabeen Group

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

P500 Mid Capitanian Base Tomago Coal Measures Base Wittingham Coal Measures Base Illawarra Coal Measures Base Illawarra Coal Measures

P550 Top Wordian Base Mulbring Siltstone Base Mulbring Siltstone Base Berry Siltstone Base Berry Siltstone

P600 Mid Roadian Base Maitland Group Base Maitland Group Base Shoalhaven Group Base Shoalhaven Group

P700 Upper Kungurian Top Base Greta Coal Measures Top Base Greta Coal Measures

P900 Base Serpukhovian Base Seaham Formation Base Seaham Formation

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

Data was originally sourced from 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 shapefiles.
