Regional Three-Dimensional Geological Model for the Beetaloo Sub-basin

\n## **Abstract** \nThis dataset contains the integrated surfaces form a three-dimensional geological model that was used as a visualisation tool in assessing the structural and stratigraphic framework of the Beetaloo GBA region and assisted in assessing the unconventional gas resource prospectivity and potential impacts associated with their development. These surfaces and can be accessed using most 3D-software packages.\n\n\n## **Attribution** \nGeological and Bioregional Assessment Program\n\n\n## **History** \nOrr et al. (2020) published regional three-dimensional depth and isochore maps for key stratigraphic horizons of the Beetaloo Sub-basin and overlying Paleozoic (Georgina/Wise/Daly) and Mesozoic (Carpentaria) basins. These maps are based on: published depth maps of Frogtech Geoscience (2018a; 2018b), Department of Environment and Natural Resources (NT) (2018a; 2018b), Randal (1973), Hutchinson et al. (2008); seismic interpretation of Williams (2019), and; additional modelled surfaces based on formation top picks contained in well completion reports (Northern Territory Government, 2018). For full details on the inputs and methods used to compile the three-dimensional model refer to Orr et al. (2020).

## **摘要**
本数据集包含源自一套三维地质模型的整合曲面。该模型曾作为可视化工具，用于评估比塔卢GBA（Beetaloo GBA）区域的构造与地层格架，并辅助评估非常规天然气资源的勘探潜力，以及其开发活动相关的潜在影响。此类曲面可通过绝大多数三维软件包读取与访问。

## **编制历程**
Orr等人（2020年）发布了比塔卢次盆地以及上覆古生界（乔治娜/怀斯/戴利盆地）和中生界（卡彭塔里亚盆地）关键地层层面的区域三维深度图与等厚线图。上述地图的编制依据包括：Frogtech Geoscience（2018a；2018b）、北领地环境与自然资源部（2018a；2018b）、Randal（1973）、Hutchinson等（2008）发布的深度图；Williams（2019）的地震解释成果；以及基于北领地政府（2018）发布的完井报告中地层顶界拾取数据生成的额外建模曲面。若需了解该三维模型编制所用的输入数据与方法的完整细节，请参阅Orr等人（2020年）的相关研究。
