## **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\nSupplemental_Information:\n\n Data captured at 1:40 000 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.\n\n\n\n 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\n\n\n\nEntity_and_Attribute_Information:\n\n\n\n Detailed_Description:\n\n\n\n Entity_Type:\n\n\n\n Entity_Type_Label: 9341_r\n\n Entity_Type_Definition:\n\n Polygons have a range of attributes including unit name, age, lithological description and an abbreviated symbol for use in labelling the polygons. \n\n Entity_Type_Definition_Source:\n\n The Rock Units Table held in the Department of Natural Resources, Mines and Energy Merlin Database. \n\n\n\n Attribute:\n\n\n\n Attribute_Label: FID\n\n Attribute_Definition: Internal feature number.\n\n Attribute_Definition_Source: ESRI\n\n Attribute_Domain_Values:\n\n\n\n Unrepresentable_Domain:\n\n Sequential unique whole numbers that are automatically generated. \n\n\n\n Beginning_Date_of_Attribute_Values: March 2004\n\n\n\n Attribute:\n\n\n\n Attribute_Label: Shape\n\n Attribute_Definition: Feature geometry.\n\n Attribute_Definition_Source: ESRI\n\n Attribute_Domain_Values:\n\n\n\n Unrepresentable_Domain: Coordinates defining the features.\n\n\n\n Attribute:\n\n\n\n Attribute_Label: KEY\n\n Attribute_Definition: Unique polygon identifier and relate item for poygon attributes\n\n\n\n Attribute:\n\n\n\n Attribute_Label: ROCK_U_NAM\n\n Attribute_Definition:\n\n The Map Unit Name of the polygon.

This item will contain one of the following: STRAT- Stratigraphic unit, including sedimentary, volcanic and metamorphic rock units. INTRU- Intrusive rock units; COMPST- Compound unit where the polygon includes two or more rock units, either stratigraphic, intrusive or both; COMPST- Compound unit, as above where the dominant or topmost unit is of the STRAT type; COMPIN- Compound unit, as above, where the dominant unit is of the INTRU type; WATER- Water bodies- Large dams, lakes, waterholes. \n\n\n\n Attribute:\n\n\n\n Attribute_Label: SEQUENCE_N\n\n Attribute_Definition:\n\n A numeric field to allow sorting of the rock units in approximate stratigraphic order as they would appear on a map legend. \n\n\n\n Attribute:\n\n\n\n Attribute_Label: DOMINANT_R\n\n Attribute_Definition:\n\n A simplified lithological description to allow generation of thematic maps based on broad rock types. \n\n\n\n Attribute:\n\n\n\n Attribute_Label: MAP_SYMBOL\n\n Attribute_Definition:\n\n Provides an abbreviated label for polygons. Mostly based on the letter symbols as they appear on published maps or the original hard copy compilation sheets. These are not unique across the State, but should be unique within a single map tile, and usually adjacent tiles. \n\n\n\n Attribute:\n\n\n\n Attribute_Label: NAME_100K\n\n Attribute_Definition: Name of 1:100 000 map sheet coincident with the data extent.\n\n\n\n Overview_Description:\n\n\n\n Entity_and_Attribute_Overview:\n\n Polygon Attribute information includes Polygon Key, Rock Unit Name, Age, Lithology, Rock Unit Type, Map Symbol and 1:100 000 sheet name.\n\n## **Dataset Citation** \n\n"Queensland Department of Natural Resources, Mines and Energy" (2014) Qld 100k mapsheets - Warwick.

## **摘要**

本数据集及其元数据声明由第三方提供给生物区域评估计划（Bioregional Assessment Programme），此处按原始提交内容呈现。本数据集内的多边形为研究区内地质单元分布或范围的数字化表征。多边形包含多种属性，包括单元名称、年代、岩性描述以及用于多边形标注的缩写符号。这些信息提取自自然资源、矿产与能源部默林数据库（Merlin Database）中的岩石单元表。

## **用途**

用于展示划定岩石单元分布范围的地质多边形要素。

## **数据集历史**

补充信息:

数据以1:4万比例尺采集。本数据集源自该部的地质与资源数据库（Geoscience and Resources Database，GRDB），其为矿产与能源资源位置与信息网络（Mineral and Energy Resources Location and Information Network，MERLIN）企业级数据库的组成部分。(GRDB), a component of the Mineral and Energy Resources Location and Information Network (MERLIN) corporate database.

注意：GEOLDATA在大多数情况下基于AGD66基准面（Datum AGD66）编制。由此编制的地图图幅覆盖范围现已投影至基于GDA94基准面（Datum GDA94）的地理坐标系。因此，这些地图图幅的边界将与基于GDA94基准面的经纬格网不重合。
