Australian Geological Provinces, v02

## **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 elements of the Australian continent and offshore surrounds. Province types include sedimentary basins, tectonic provinces such as cratons and orogens, igneous provinces, and metallogenic provinces. Spatial data has been captured largely at approximately 1:1M scale for intended use between 1:2M and 1:5M scale. This edition (2013.01) of the dataset is NOT a complete representation of all of Australia's geological provinces. Further work is required to complete the national geological province collection. Additionally, not all the provinces supplied herein have undergone a rigorous quality assurance (QA) check to ensure the accuracy and completeness of their descriptions. Where possible, provinces have been attributed with their age, contained lithostratigraphic units, relationships to other provinces, geological history, mineral resource occurrences, and selected published references. The geological definition of some provinces is contentious. While every effort has been made to achieve a consensus interpretation of each province, including significant collaboration with state and territory geological surveys, scientific debate may still occur about the nature and extent of some provinces. The full 2D spatial extent (ie, including the extent of a province under any overlying cover material) of provinces has been captured in Province Full Extent.\n\n\n\nFull Metadata attached to the spatial dataset, viewable in ArcCatalog.\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\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,+2013.01+edition\n\n## **Dataset Citation** \n\nGeoscience Australia (2013) Australian Geological Provinces, v02.

## **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项目（Bioregional Assessment Programme），本文将按原始提交的形式予以呈现。

澳大利亚地质省份数据库（Australian Geological Provinces Database）收录了澳大利亚大陆及周边海域基础地质要素的描述信息与空间范围数据。地质省份类型涵盖沉积盆地、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，可适配1:200万至1:500万比例尺的应用场景。

本数据集2013.01版本并未完整涵盖澳大利亚所有地质省份，仍需开展后续工作以完善全国地质省份数据集。此外，本数据集收录的所有省份并非均经过严格的质量保证（QA）审查以确保其描述的准确性与完整性。在可行范围内，已为各省份标注其形成时代、赋存的岩石地层单元、与其他省份的关联关系、地质演化历史、矿产资源产地以及选定的已发表参考文献。部分省份的地质定义尚存争议。尽管项目组已尽最大努力达成各省份的共识性解译，包括与各州及领地地质调查机构开展了大量协作，但针对部分省份的属性与范围仍可能存在科学争议。各省份的完整二维空间范围（即包含被上覆覆盖层掩埋的省份范围）已收录于「省份完整范围」（Province Full Extent）图层中。

空间数据集附带完整元数据，可在ArcCatalog中查看。

## **数据集历史**

空间数据（多边形与线要素）通常以1:100万左右的比例尺，基于大量公开的地表地质图、基岩/基底地质图、钻孔数据以及地球物理影像编制而成。当省份边界跨越行政辖区边界时，澳大利亚地质调查局（Geoscience Australia）已与各州及领地地质机构协作，达成统一的空间范围共识。描述性属性数据尽可能基于权威公开文献编制，相关参考文献名称随数据集一并提供。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。本版数据集的所有省份描述均会标注对应数据是否已通过核查。
