## **Abstract** \n\nThis dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied. The polygons in this dataset are a digital representation of the distribution or extent of geological units within the area. Polygons have a range of attributes including unit name, age, lithological description and an abbreviated symbol for use in labelling the polygons. These have been extracted from the Rock Units Table held in the Department of Natural Resources, Mines and Energy Merlin Database.\n\n## **Purpose** \n\nTo display the geology polygons which define the extent of rock units.\n\n## **Dataset History** \n\nData captured at 1:25 000 scale. The data set is sourced from the Department's Geoscience and Resources Database (GRDB), a component of the Mineral and Energy Resources Location and Information Network (MERLIN) corporate database.(GRDB), a component of the Mineral and Energy Resources Location and Information Network (MERLIN) corporate database. NOTE: GEOLDATA was in most cases compiled based on Datum AGD66. The map tile coverages so compiled have now been projected to geographics based on Datum GDA94. Consequently the boundaries for these map tiles will not conform to the Latitude and Longitude graticule based on Datum GDA94.\n\n## **Dataset Citation** \n\n"Queensland Department of Natural Resources, Mines and Energy" (2014) Qld 100K mapsheets - Caboolture.

## **摘要**

本数据集及其元数据声明由第三方提交至生物区域评估计划（Bioregional Assessment Programme），此处按原始提交版本原样呈现。本数据集内的多边形为研究区域内地质单元分布与范围的数字化表征。多边形附带多类属性项，包括单元名称、形成年代、岩性描述以及用于多边形标注的缩写符号。所有数据均源自昆士兰州自然资源、矿产与能源部（Department of Natural Resources, Mines and Energy）默林数据库（Merlin Database）中存储的岩石单元表。

## **用途**

用于展示划定岩石单元范围的地质多边形。

## **数据集历史**

数据以1:25000比例尺采集。本数据集源自该部门的地球科学与资源数据库（Geoscience and Resources Database, 缩写GRDB），其隶属于矿产与能源资源定位与信息网络（Mineral and Energy Resources Location and Information Network, 缩写MERLIN）企业级数据库。注：GEOLDATA数据集多数情况下基于AGD66大地基准面编绘。目前上述编绘的地图瓦片覆盖范围已被投影至基于GDA94大地基准面的地理坐标系中，因此这些地图瓦片的边界将与基于GDA94大地基准面的经纬网格不完全重合。
