CLM - Koukandowie FM bedrock

## **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 Koukandowie Formation in the CLM bioregion. It is compiled from several sources, including Qld and NSW surface geological maps and well data. In many areas, the exact extent is not well constrained, as this bedrock unit is covered by younger rocks or sediments. Where this is the case, the hard data have been combined with geological expert knowledge. The final shapefile has been created from all sources and expert knowledge in GoCAD.\n\n## **Dataset History** \n\nThis shapefile is compiled from several sources: the digital 1:100000 surface geology map sheet (Qld Geological Survey) and 1:250000 surface geological map obtained from the Clarence-Moreton SEEBASE project in NSW (see lineage).\n\n\n\nIn some areas, the exact extent of the Koukandowie Formation is not well constrained, as this bedrock unit is covered by younger rocks (e.g. volcanic rocks) or allvuium. Where this is the case, the original maps which only show the presence of the Koukandowie Formation 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 - Koukandowie FM bedrock.

## **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。本元数据声明中的谱系（Lineage）字段已标注所用源数据集的相关信息，而该衍生数据集的制作流程则见本元数据声明中的历史（History）字段。

本形状文件展示了CLM生物区域内库坎道伊组（Koukandowie Formation）的分布范围，其整合了多类数据源，包括昆士兰州（Qld）与新南威尔士州（NSW）的地表地质图及钻井数据。由于该基岩单元常被更年轻的岩石或沉积物覆盖，多数区域内其精确分布范围难以精准限定。针对此类情况，研究团队将实测数据与地质专家经验知识相结合，最终依托GoCAD软件整合所有数据源及专家知识生成本形状文件。

## **数据集历史**

本形状文件整合自多类数据源：昆士兰州地质调查局（Qld Geological Survey）发布的数字化1:100000比例尺地表地质图幅，以及从新南威尔士州克拉伦斯-莫顿SEEBASE项目获取的1:250000比例尺地表地质图（详见谱系字段）。

部分区域内，库坎道伊组的精确分布范围仍难以精准限定，因该基岩单元被更年轻的岩石（如火山岩）或冲积层覆盖。针对此类场景，研究团队将仅标注地表出露库坎道伊组的原始图件，与地质专家经验知识相结合，并依托Paradigm Geophysical Pty Ltd开发的GoCAD™三维地质建模软件进行人工插值（数字化）处理，以补充该单元未在地表出露区域的分布范围。最终本形状文件即通过整合所有数据源与专家知识，在GoCAD环境中生成。
