Lockyer Valley GW bores stratigraphy

## **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 dataset contains two EXCEL spreadsheets:\n\n\n\n1) a spreadsheet showing the location (easting and northing) of groundwater bores in the Lockyer Valley, the elevation of the bore location and the depth of the bore\n\n2) a shreadsheet that contains the cleaned stratigraphic data of groundwater bores (in many cases converted from lithological logs in the QLD DNRM groundwater database).\n\n## **Dataset History** \n\nThis dataset contains two EXCEL spreadsheets:\n\n\n\n1) a spreadsheet showing the location (easting and northing) of groundwater bores in the Lockyer Valley, the elevation of the bore location and the depth of the bore\n\n2) a shreadsheet that contains the cleaned stratigraphic data of groundwater bores (in many cases converted from lithological logs in the QLD DNRM groundwater database).\n\n\n\nThe following steps were involved in deriving the stratigraphic logs of the groundwater bores:\n\n\n\n1) Ensure consistent use of terminology and spelling. \n\n2) Identification of geological inconsistencies or geological errors\n\n3) Verification of bore elevation data. \n\n4) Simplification of lithological logs. \n\n5) Conversion of lithological logs into stratigraphic logs. \n\n\n\nThe procedure is described in detail in Clarence-Moreton bioregional assessment product 2.1 (Raiber et al., 2016).\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (XXXX) Lockyer Valley GW bores stratigraphy.

**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所得。元数据声明中的“谱系（Lineage）”字段已标注所用源数据集，元数据声明中的“历史（History）”字段则详述了本衍生数据集的生成流程。

本数据集包含两份Excel电子表格：
1. 记录洛克耶谷（Lockyer Valley）地下水钻孔位置（东距与北距，easting and northing）、钻孔位置高程及钻孔深度的电子表格；
2. 包含经清理的地下水钻孔地层数据（stratigraphic data）（多数由昆士兰州自然资源与矿业部（QLD DNRM）地下水数据库中的岩性测井曲线（lithological logs）转换而来）的电子表格。

**数据集历史**
本数据集包含两份Excel电子表格：
1. 记录洛克耶谷地下水钻孔位置（东距与北距）、钻孔位置高程及钻孔深度的电子表格；
2. 包含经清理的地下水钻孔地层数据（多数由昆士兰州自然资源与矿业部地下水数据库中的岩性测井曲线转换而来）的电子表格。

生成地下水钻孔地层测井曲线（stratigraphic logs）的流程如下：
1. 统一术语使用与拼写规范；
2. 识别地质不一致性与地质错误；
3. 校验钻孔高程数据；
4. 简化岩性测井曲线；
5. 将岩性测井曲线转换为地层测井曲线。

该流程的详细说明见于《克拉伦斯-莫顿生物区域评估产品2.1》（Raiber等，2016）。
