Werrie Basin component of the Hunter subregion extent

## **Abstract** \n\nThe dataset is derived from the Australian Coal Basins dataset supplied by Geoscience Australia. You can find a link to the parent datasets in the Lineage Field in this metadata statement. The History Field in this metadata statement describes how this dataset was derived. \n\nThis is the eastern discontiguous part of what the GA Coal Basins dataset has included as "Gunnedah (coal) Basin". However other sources refer to the coal deposit east of the Hunter-Mooki thrust fault as the "Werrie Basin". This area has been extracted from the GA Coal Basins dataset and re-attributed from "Gunnedah Basin" to "Werrie Basin". It is intended for use in report map images only.\n\n\n\nSource dataset abstract follows:\n\n\n\nThe Coal Basin Outlines dataset is a combination of data from various sources displaying the best available (7 March 2013) coal basin extents for all of Australia. These extents were taken predominantly from the Australian Geological Provinces Database(extract from 4 November 2012 - see metadata statement below) with additional data coming from the Australian Sedimentary Basins Database(27 August 2012 update), State (South Australia) basin databases and hydrogeological basin databases.\n\n\n\nThe Australian Geological Provinces Database contains descriptions and spatial extents of the fundamental geological elements of the Australian continent and immediate surrounds. Captured 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 best use at between 1:2M to 1:5M scale.\n\nWhere possible, provinces have been attributed with their age, contained lithostratigraphic units, relationships to other provinces, and geological history. The geological definition of some provinces, in particular certain sedimentary basins and orogens, is contentious. While every effort has been made to achieve a consensus interpretation 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 under any overlying cover). The extent of outcrop of some provinces has also been captured. Where possible, the full extent outlines of provinces have been attributed with information about the source, accuracy, and observation method of those lines.\n\n## **Dataset History** \n\nThe section of the Gunnedah Basin in the Australian Coal Basins dataset (see lineage) lying east of the Hunter-Mooki fault was extracted and the attibution in the 'Name' field changed from "Gunnedah Basin" to "Werrie Basin"\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2014) Werrie Basin component of the Hunter subregion extent.

## **摘要**

本数据集源自澳大利亚地质科学局（Geoscience Australia）提供的澳大利亚煤盆地数据集。父数据集的链接可在本元数据声明的谱系字段（Lineage Field）中找到。本元数据声明的历史字段（History Field）描述了本数据集的衍生过程。

本数据集对应澳大利亚地质科学局（GA）煤盆地数据集中所包含的"冈尼达（煤）盆地（Gunnedah (coal) Basin）"的东部不连续部分。然而，其他资料将亨特-穆基逆冲断层（Hunter-Mooki thrust fault）以东的煤矿床称为"韦里盆地（Werrie Basin）"。该区域已从澳大利亚地质科学局（GA）煤盆地数据集中提取，并将属性从"冈尼达盆地"重新归属为"韦里盆地"。本数据集仅用于报告地图图像。

源数据集摘要如下：

煤盆地轮廓数据集（Coal Basin Outlines dataset）整合了来自多种来源的数据，展示了澳大利亚境内截至2013年3月7日的最佳可用煤盆地范围。这些范围主要取自澳大利亚地质省数据库（Australian Geological Provinces Database，2012年11月4日提取——详见下文元数据声明），补充数据则来自澳大利亚沉积盆地数据库（Australian Sedimentary Basins Database，2012年8月27日更新）、州级（南澳大利亚州）盆地数据库及水文地质盆地数据库。

澳大利亚地质省数据库（Australian Geological Provinces Database）包含澳大利亚大陆及其邻近区域基本地质单元的描述和空间范围。所收录的省类型包括沉积盆地、构造省（如克拉通和造山带）、火成岩省及成矿省。空间数据主要以约1:100万比例尺采集，以便在1:200万至1:500万比例尺下最佳使用。在可能的情况下，各省份已被赋予其时代、所含岩石地层单元、与其他省份的关系及地质历史等属性。

部分省份（尤其是某些沉积盆地和造山带）的地质定义存在争议。尽管已尽最大努力对每个省份达成共识性解释，但关于部分省份的性质和范围仍可能存在科学争论。

数据库中大多数省份的完整二维空间范围已被采集（即，任何上覆覆盖层下的省份完整范围）。部分省份的出露范围也已被采集。在可能的情况下，省份的完整范围轮廓已被赋予这些线条的来源、准确性和观测方法等信息。

## **数据集历史**

从澳大利亚煤盆地数据集中提取了位于亨特-穆基逆冲断层以东的冈尼达盆地部分（详见谱系），并将"名称"字段中的属性从"冈尼达盆地"更改为"韦里盆地"
