Cooper Formations Merged Isopach Grids v01

## **Abstract** \n\nThis dataset was derived by the Bioregional Assessment Programme. The parent 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 dataset merges formation isopach grids for the Nappamerri Group, Patchawarra Formation and Toolachee Formation in the Cooper Basin from South Australia and Queensland datasets, to produce a single, whole of formation isopach grid for each formation.\n\n## **Purpose** \n\nCombines formation isopach grid data from different states into a single, whole of formation isopach grid for each formation. Created to standardise Cooper Formation isopach values for visualisation across QLD and SA.\n\n## **Dataset History** \n\nSouth Australia - SA Cooper Basin Seismic Mapping Grids datasets (GUID: cdd1625e-64e1-41da-bff4-2e26d0fd4ad1) - and Queensland - QLD GSQ Cooper formation thickness grids v01 (GUID: 2cabb0d5-1d99-494b-9497-2bf107bf2bdd) - formation thickness grids for the Nappamerri Group, Patchawarra Formation and Toolachee Formation were merged together in ArcGIS using the Mosaic (Data Management) tool. A single grid output was created for each formation. The following combinations of inputs created each corresponding output:\n\n\n\n1.

## 摘要

本数据集由生物区域评估计划（Bioregional Assessment Programme）衍生生成。其源数据集已在本元数据声明的“谱系（Lineage）”字段中列明，制备该衍生数据集的具体流程则记载于本元数据声明的“历史（History）”字段中。

本数据集整合了来自南澳大利亚州与昆士兰州的库珀盆地（Cooper Basin）内纳帕默里群（Nappamerri Group）、帕奇沃拉地层（Patchawarra Formation）及图拉切地层（Toolachee Formation）的地层等厚网格（isopach grid）数据，为每个地层生成一套完整的全域等厚网格。

## 用途

将来自不同州的地层等厚网格数据整合为单套完整的地层全域等厚网格，旨在统一库珀盆地各地层的等厚数值，以支撑昆士兰州与南澳大利亚州范围内的可视化工作。

## 数据集历史

南澳大利亚州库珀盆地地震填图网格数据集（GUID: cdd1625e-64e1-41da-bff4-2e26d0fd4ad1）与昆士兰州GSQ库珀盆地地层厚度网格v01数据集（GUID: 2cabb0d5-1d99-494b-9497-2bf107bf2bdd）中，纳帕默里群、帕奇沃拉地层及图拉切地层的地层厚度网格数据，通过ArcGIS的镶嵌（数据管理）工具（Mosaic (Data Management)）完成合并，最终为每个地层生成一套独立的网格输出成果。各输出成果对应的输入组合如下：
