Australian Geological Provinces 2018.01 edition
收藏资源简介:
The 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 (2018.01) 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. Additionally, 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.
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与空间范围数据。该数据库涵盖的省份类型包括沉积盆地、克拉通与造山带等构造省、火成岩省以及成矿省。空间数据主要以1:100万比例尺采集,适配1:200万至1:500万比例尺的应用需求。 本数据集2018.01版本并未完整覆盖澳大利亚所有地质省份,国家地质省份数据集的完善工作仍需推进。此外,本次收录的部分省份尚未经过严格的质量保证(QA)检查,无法确保其描述的准确性与完整性。 在条件允许的情况下,数据库会为省份标注其形成年代、所含岩石地层单位、与其他省份的关联关系、地质演化历史、矿产资源产出情况以及选定的公开参考文献。部分省份的地质定义尚存争议,尽管研究团队已联合各州及领地地质调查机构开展协作,尽可能达成共识性解释,但针对部分省份的属性范围与本质特征,仍可能存在科学争议。 数据库已采集所有省份的完整二维空间范围(即包含被上覆覆盖层掩盖的省份范围),部分省份的露头范围亦被纳入采集范畴。若条件允许,省份完整范围的轮廓数据会附带其来源、精度及观测方法等相关属性信息。
