Queensland geology and structural framework - GIS data July 2012

## **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.\n\n\n\nThis dataset was sourced from the Queensland Department of Natural Resources and Mines in 2012. Information provided by the Department describes the dataset as follows:\n\n\n\nThis data was originally provided on DVD and contains the converted shapefiles, layer files, raster images and project .mxd files used on the Queensland geology and structural framework map. The maps were done in ArcGIS 9.3.1 and the data stored in file geodatabases, topology created and validated. This provides greater data quality by performing topological validation on the feature's spatial relationships. For the purposes of the DVD, shapefiles were created from the file geodatabases and for MapInfo users MapInfo .tab and .wor files. The shapefiles on the DVD are a revision of the 1975 Queensland geology data, and are both are available for display, query and download on the department's online GIS application.\n\n\n\nThe Queensland geology map is a digital representation of the distribution or extent of geological units within Queensland. In the GIS, polygons have a range of attributes including unit name, type of unit, age, lithological description, dominant rock type, and an abbreviated symbol for use in labelling the polygons. The lines in this dataset are a digital representation of the position of the boundaries of geological units and other linear features such as faults and folds. The lines are attributed with a description of the type of line represented. Approximately 2000 rock units were grouped into the 250 map units in this data set. The digital data was generalised and simplified from the Department's detailed geological data and was captured at 1:500 000 scale for output at 1:2 000 000 scale. \n\n\n\nIn the ESRI version, a layer file is provided which presents the units in the colours and patterns used on the printed hard copy map. For Map Info users, a simplified colour palette is provided without patterns. However a georeferenced image of the hard copy map is included and can be displayed as a background in both Arc Map and Map Info.\n\n\n\nThe geological framework of Queensland is classified by structural or tectonic unit (provinces and basins) in which the rocks formed. These are referred to as basins (or in some cases troughs and depressions) where the original form and structure are still apparent. Provinces (and subprovinces) are generally older basins that have been strongly tectonised and/or metamorphosed so that the original basin extent and form are no longer preserved. Note that intrusive and some related volcanic rocks that overlap these provinces and basins have not been included in this classification. The map was compiled using boundaries modified and generalised from the 1:2 000 000 Queensland Geology map (2012). Outlines of subsurface basins are also shown and these are based on data and published interpretations from petroleum exploration and geophysical surveys (seismic, gravity and magnetics).\n\n\n\nFor the structural framework dataset, two versions are provided. In QLD_STRUCTURAL_FRAMEWORK, polygons are tagged with the name of the surface structural unit, and names of underlying units are imbedded in a text string in the HIERARCHY field. In QLD_STRUCTURAL_FRAMEWORK_MULTI_POLYS, the data is structured into a series of overlapping, multi-part polygons, one for each structural unit. Two layer files are provided with the ESRI data, one where units are symbolised by name. Because the dataset has been designed for units display in the order of superposition, this layer file assigns colours to the units that occur at the surface with concealed units being left uncoloured. Another layer file symbolises them by the orogen of which they are part. A similar set of palettes has been provided for Map Info.\n\n## **Dataset History** \n\nDetails on the source data can be found in the xml file associated with data layer.\n\n\n\nData in this release\n\n \\*ESRI.shp and MapInfo .tab files of rock unit polygons and lines with associated layer attributes of Queensland geology\n\n \\*ESRI.shp and MapInfo .tab files of structural unit polygons and lines with associated layer attributes of structural framework\n\n \\*ArcMap .mxd and .lyr files and MapInfo .wor files containing symbology\n\n \\*Georeferenced Queensland geology map, gravity and magnetic images\n\n \\*Queensland geology map, structural framework and schematic diagram PDF files\n\n \\*Data supplied in geographical coordinates (latitude/longitude) based on Geocentric Datum of Australia - GDA94\n\n\n\nAccessing the data\n\n\n\nPrograms exist for the viewing and manipulation of the digital spatial data contained on this DVD.

**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），此处按原始提供的内容呈现。

本数据集于2012年源自昆士兰州自然资源与矿产部（Queensland Department of Natural Resources and Mines）。该部门提供的信息对数据集的描述如下：

本数据最初以DVD形式交付，包含用于昆士兰州地质与构造框架地图的转换后形状文件（shapefiles）、图层文件（layer files）、栅格图像（raster images）以及项目.mxd文件。这些地图基于ArcGIS 9.3.1制作，数据存储于文件地理数据库（file geodatabases）中，并完成了拓扑（topology）创建与验证。通过对要素空间关系开展拓扑验证，可有效提升数据质量。为适配DVD载体，从文件地理数据库中导出了形状文件；针对MapInfo用户，则提供了MapInfo .tab与.wor文件。DVD中的形状文件是1975年昆士兰州地质数据的修订版，二者均可在该部门的在线地理信息系统（GIS）应用中进行查看、查询与下载。

昆士兰州地质地图是昆士兰州境内地质单元分布或范围的数字化表现。在地理信息系统（GIS）中，多边形要素包含一系列属性，包括单元名称、单元类型、形成年代、岩性描述（lithological description）、主导岩石类型，以及用于标注多边形的缩写符号。本数据集中的线条是地质单元边界及断层（faults）、褶皱（folds）等其他线性要素位置的数字化表现，线条附带其所代表的线条类型的描述信息。约2000个岩石单元被归为本次数据集中的250个地图单元。本次数字化数据系由该部门的详细地质数据经概括与简化而成，采集比例尺为1:500 000，输出比例尺为1:2 000 000。

在ESRI版本中，提供了一个图层文件，该文件采用印刷纸质地图所用的颜色与图案来呈现各单元。对于MapInfo用户，提供了无图案的简化调色板（colour palette）。不过，纸质地图的地理配准图像（georeferenced image）已包含在内，可在ArcMap与MapInfo中作为背景图层显示。

昆士兰州的地质框架按照岩石形成所处的构造或构造单元（structural or tectonic unit）进行分类，分为省（provinces）与盆地（basins）。其中，原始形态与结构仍清晰可见的被称为盆地（部分情况下为槽地（troughs）与凹陷（depressions））。省（及亚省（subprovinces））通常是经历了强烈构造作用和/或变质改造（metamorphosed）的古老盆地，其原始盆地范围与形态已无法保留。需注意，覆盖这些省与盆地的侵入岩（intrusive rocks）及部分相关火山岩（volcanic rocks）未纳入本次分类。本地图基于1:2 000 000比例尺昆士兰州地质地图（2012年版）的修改与概括后的边界编制而成。地下盆地（subsurface basins）的轮廓亦一并展示，该类轮廓基于石油勘探（petroleum exploration）与地球物理勘探（geophysical surveys，涵盖地震（seismic）、重力（gravity）与磁法（magnetics）勘探）的数据及已发表的解译成果。

针对构造框架数据集，本次发布提供了两个版本。在QLD_STRUCTURAL_FRAMEWORK中，多边形要素标注有地表构造单元名称，而下伏单元的名称嵌入在层级（HIERARCHY）字段的文本字符串中。在QLD_STRUCTURAL_FRAMEWORK_MULTI_POLYS中，数据被组织为一系列重叠的多部分多边形，每个构造单元对应一个多边形。ESRI数据附带两个图层文件：一个按单元名称进行符号化。由于本数据集旨在按叠置（superposition）顺序展示单元，该图层文件为地表出露的单元分配颜色，隐伏单元则不进行着色。另一个图层文件则依据单元所属的造山带（orogen）进行符号化。MapInfo也提供了一套类似的调色板。
