Permian Outcrop Northern Territory - PED

## **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\nThe Surface Geology of Australia 1:1M scale dataset (2012 edition) is a seamless national coverage of outcrop and surficial geology, compiled for use at or around 1:1 million scale. The data maps outcropping bedrock geology and unconsolidated or poorly consolidated regolith material covering bedrock. Geological units are represented as polygon and line geometries, and are attributed with information regarding stratigraphic nomenclature and hierarchy, age, lithology, and primary data source. The dataset also contains geological contacts, structural features such as faults and shears, and miscellaneous supporting lines like the boundaries of water and ice bodies. This file is an extract of geological unit outcrops for Crown Point Formation in the vicinity of the Pedirka Basin within the Northern Territory.\n\n## **Purpose** \n\nThis file is used to indicate the occurrence and extent of outcropping Crown Point Formation rocks, in the vicinity of the Pedirka Subregion.\n\n## **Dataset History** \n\nSelection from 1:1M surface geology of Australia (Custodian: Geoscience Australia) showing surface extent of the Crown Point Formation. The 2012 dataset has been updated from the previous 2010 data by updating geological unit data to 2012 information in the Australian Stratigraphic Units Database (http://www.ga.gov.au/products-services/data-applications/reference-databases/stratigraphic-units.html), incorporating new published mapping in the Northern Territory and Queensland, and correcting errors or inconsistent data identified in the previous edition, particularly in the Phanerozoic geology of Western Australia. The attribute structure of the dataset has also been revised to be more compatible with the GeoSciML data standard, published by the IUGS Commission for Geoscience Information.

**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），本文档将按原始提供的形式予以呈现。

澳大利亚1:100万比例尺地表地质数据集（2012版）是一套覆盖全国的露岩与表层地质无缝数据集，专为1:100万比例尺或相近比例尺的应用场景编制。该数据集描绘了出露的基岩地质，以及覆盖基岩的未固结或弱固结的风化层（regolith）材料。地质单元以多边形与线要素几何形态进行表示，并附带地层命名与层级、年代、岩性以及原始数据源等属性信息。本数据集还包含地质接触界线、断层与剪切带等构造特征，以及水体、冰体边界等各类辅助线要素。本文件为北领地（Northern Territory）佩迪尔卡盆地（Pedirka Basin）周边区域的克朗波因特组（Crown Point Formation）露岩地质单元提取子集。

**用途**

本文件用于标识佩迪尔卡次区域（Pedirka Subregion）周边区域出露的克朗波因特组岩石的产出位置与分布范围。

**数据集历史**

本数据集源自澳大利亚1:100万地表地质数据集（管理方：澳大利亚地质调查局（Geoscience Australia）），用于展示克朗波因特组的地表分布范围。2012版数据集相较于2010版旧数据完成了多项更新：将地质单元数据更新为澳大利亚地层单元数据库（Australian Stratigraphic Units Database，http://www.ga.gov.au/products-services/data-applications/reference-databases/stratigraphic-units.html）2012年的相关信息；纳入北领地与昆士兰州最新公开的填图成果；修正了旧版数据集（尤其是西澳大利亚州显生宙（Phanerozoic）地质部分）中存在的错误与不一致数据。本数据集的属性结构也进行了修订，以更好地适配国际地质科学联合会地质信息委员会（IUGS Commission for Geoscience Information）发布的GeoSciML数据标准。原始澳大利亚地质调查局数据集名称：GeologicalUnits_1m_Polys_PED.shp
