Geological Provinces - Full Extent

## **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\nThe Australian Geological Provinces Database contains descriptions and spatial extents of the fundamental geological \n\nelements of the Australian continent and immediate surrounds. Captured province types include sedimentary basins, \n\ntectonic provinces such as cratons and orogens, igneous provinces, and metallogenic provinces. Spatial data has \n\nbeen captured largely at approximately 1:1M scale for best use at between 1:2M to 1:5M scale\n\n\n\nWhere possible, provinces have been attributed with their age, contained lithostratigraphic units, relationships \n\nto other provinces, and geological history. The geological definition of some provinces, in particular certain \n\nsedimentary basins and orogens, is contentious. While every effort has been made to achieve a consensus \n\ninterpretation of each province, scientific debate may still occur about the nature and extent of some provinces.\n\n\n\nThe total 2D spatial extent of most provinces in the database has been captured (ie, the full extent of a province \n\nunder any overlying cover). The extent of outcrop of some provinces has also been captured. Where possible, the \n\nfull extent outlines of provinces have been attributed with information about the source, accuracy, and observation \n\nmethod of those lines.\n\n\n\nFeature Classes\n\n\n\nProvinceFullExtent - polygons showing the full 2D spatial extent of a province. This includes non-outcropping \n\nregions of a province that may be concealed by regolith or other overlying provinces. The ProvinceFullExtent\n\nfeature class has two related tables, linked through relationship classes:\n\n\n\n- ProvinceRelations - this table lists relationships between provinces (eg, the Surat Basin overlies the \n\nBowen Basin)\n\n- ProvinceStratigraphy - this table list the stratigraphic units contained within a province. Full details of \n\neach stratigraphic unit are available at http://dbforms.ga.gov.au/www/geodx.strat_units.int\n\n\n\nProvinceOutcrop - polygons showing the outcropping extent of a province. Note that not all provinces have this \n\ndata available.\n\n\n\nProvinceFullExtentBdy - lines overlying the margins of province full extent polygons showing the nature of contacts \n\nbetween provinces, data source, and spatial accuracy. Note that not all provinces have this data available.\n\n## **Dataset History** \n\nThe spatial data (polygons and lines) was compiled typically at or around 1:1 million scale from a wide range of published surface geology maps, bedrock or basement geology maps, borehole data, and geophysical imagery. Where province boundaries crossed jurisdictional borders, Geoscience Australia worked with State and Territory geological agencies to achieve an agreed spatial extent. Descriptive attribute data was compiled from authoritative published literature wherever possible, and names of these references are supplied with the data. Not all the data in this edition of the dataset (2013.01) has undergone rigorous quality control. All province descriptions in this edition of the dataset contain an indication of whether the data has been checked or not.\n\n\n\nFurther information can be found at http://www.ga.gov.au/metadata-gateway/metadata/record/gcat_c3fac1d5-48c1-624e-e044-00144fdd4fa6/Australian+Geological+Provinces%2C+2013.01+edition\n\n## **Dataset Citation** \n\nGeoscience Australia (2013) Geological Provinces - Full Extent.

**摘要**

本数据集及其元数据声明由第三方提交给生物区域评估计划（Bioregional Assessment Programme），本文档按原始提交内容呈现。

澳大利亚地质省数据库（Australian Geological Provinces Database）收录了澳大利亚大陆及邻近区域的基础地质要素的描述与空间范围数据。所收录的地质省类型包括沉积盆地、克拉通（cratons）与造山带（orogens）等构造省、火成岩省以及成矿省。空间数据主要以约1:100万比例尺采集，最佳使用比例尺为1:200万至1:500万。

尽可能为各地质省标注了其形成时代、所含岩石地层单元、与其他地质省的关联以及地质演化历史。部分地质省（尤其是特定沉积盆地与造山带）的地质定义尚存争议。尽管已尽最大努力达成各省份的共识性解译，但部分地质省的性质与范围仍可能存在科学争论。

本数据库中多数地质省的完整二维空间范围已被采集（即涵盖任何上覆覆盖层之下的地质省全部范围）。部分地质省的出露范围也已完成采集。尽可能为地质省的完整范围轮廓标注了相关数据的来源、精度与观测方法信息。

**要素类**

全省范围（ProvinceFullExtent）：用于展示地质省完整二维空间范围的多边形要素类，涵盖可能被残积层或其他上覆地质省遮蔽的非出露区域。该要素类包含两个通过关系类关联的相关数据表：

- 省际关联表（ProvinceRelations）：记录各地质省之间的相互关系（例如苏拉特盆地（Surat Basin）覆于鲍恩盆地（Bowen Basin）之上）
- 省内地层表（ProvinceStratigraphy）：列示地质省内部包含的地层单元。各地层单元的详细信息可访问http://dbforms.ga.gov.au/www/geodx.strat_units.int

出露范围（ProvinceOutcrop）：展示地质省出露区域的多边形要素类。需注意，并非所有地质省均提供该类数据。

全省范围边界（ProvinceFullExtentBdy）：叠加于全省范围多边形边界之上的线要素类，用于标注地质省之间接触带的性质、数据来源与空间精度。需注意，并非所有地质省均提供该类数据。

**数据集历史**

本空间数据（多边形与线要素）通常以约1:100万比例尺编制，数据源涵盖大量已公开的地表地质图、基岩/基底地质图、钻孔数据与地球物理影像。当地质省边界跨越行政辖区边界时，澳大利亚地质调查局（Geoscience Australia）会同各州及领地地质机构协商达成一致的空间范围。描述性属性数据尽可能从权威公开文献中汇编，相关参考文献名称随数据集一同提供。本数据集2013.01版本中的部分数据尚未经过严格的质量控制。本版本数据集的所有地质省描述均标注了该数据是否已完成核查。
