BHP mineral exploration wells 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 simple stratigraphic logs (i.e. differentiation of alluvium versus sedimentary bedrock) in .csv format.\n\n## **Purpose** \n\nThe data were used in the Clarence-Moreton bioregional assessment to help define the contact between alluvium and bedrock.\n\n## **Dataset History** \n\nThe stratigraphic logs were derived from two company reports downloaded from NSW Trade and Investment DIGS database. The bore logs were part of a mineral sand exploration programme in the Richmond river basin.\n\n\n\nReferences:\n\n\n\nDarby P (1993) CR 7942 Exploration Licence 4430 Bungawalbin Creek NSW.

**摘要**

本数据集由生物区域评估计划（Bioregional Assessment Programme）基于多份源数据集衍生而来。源数据集的相关信息已在本元数据声明的“谱系（Lineage）”字段中列明，本衍生数据集的制作流程则详见本元数据声明的“历史（History）”字段。

本数据集以逗号分隔值（.csv）格式存储简易地层测井数据，即用于区分冲积层与沉积基岩的相关内容。

## **用途**

该数据集曾应用于克拉伦斯-莫尔顿（Clarence-Moreton）生物区域评估工作，用于辅助确定冲积层与基岩的接触界面。

## **数据集历史**

本地层测井数据源自从新南威尔士州贸易与投资局（NSW Trade and Investment）DIGS数据库下载的两份企业报告。上述钻孔测井数据为里士满河流域矿物砂勘探项目的组成部分。
