CLM - Gatton Sandstone extent

## **Abstract** \n\nThe 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. \n\n\n\nThis shapefile shows the extent of the Gatton Sandstone in the CLM bioregion.\n\n## **Dataset History** \n\nIt is compiled from combined NSW and QLD geology map (see lineage).\n\n\n\nIn some areas, the exact extent of the Gatton Sandstone is not well constrained, as this bedrock unit is covered by younger rocks (e.g. volcanic rocks) or alluvium. Where this is the case, the original maps which only show the presence of the Gatton Sandstone at the surface have been combined with geological expert knowledge and manual interpolation (digitizing) using GoCAD™ (Paradigm Geophysical Pty Ltd) 3D geological modelling software to also include the extent of this unit where it is not present at the surface. The final shapefile has been created from all sources and expert knowledge in GoCAD.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2014) CLM - Gatton Sandstone extent.

## **摘要**

本数据集由生物区域评估计划（Bioregional Assessment Programme）基于多源数据集衍生而来。本元数据声明的**谱系（Lineage）**字段中列明了所用源数据集的信息，而制作该衍生数据集所采用的流程则记录于本元数据声明的**历史（History）**字段中。

本形状文件展示了CLM（克拉伦斯-莫顿，Clarence-Moreton）生物区内盖顿砂岩（Gatton Sandstone）的分布范围。

## **数据集历史**

本数据集整合了新南威尔士州（NSW）与昆士兰州（QLD）的地质图数据（详见谱系字段）。

在部分区域，由于该基岩单元被后期岩层（如火山岩）或冲积层覆盖，盖顿砂岩的确切分布范围难以精准界定。针对此类区域，研究团队将仅标注地表出露盖顿砂岩的原始地质图，与地质专家经验及使用GoCAD™（Paradigm Geophysical Pty Ltd）三维地质建模软件完成的人工插值（数字化）工作相结合，补充了地表未出露的该地层的分布范围。最终的形状文件正是基于所有源数据与专家经验，通过GoCAD软件生成的。
