Solid Geology of the North Australian Craton, 1:1 000 000 scale, 1st edition (2020)

The Solid Geology of the North Australian Craton 1:1M scale dataset 1st edition (2020) is a seamless chronostratigraphic solid geology dataset of the North Australian Craton that covers north of Western Australia, Northern Territory and north-west Queensland. The data maps stratigraphic units concealed under cover by effectively removing the overlying cover (Liu et al., 2015). This dataset comprises five chronostratigraphic time slices, namely: Cenozoic, Mesozoic, Paleozoic, Neoproterozoic, and Pre-Neoproterozoic. As an example, the Mesozoic time slice (or layer) shows Mesozoic age geology that would be present if all Cenozoic units were removed. The Pre-Neoproterozoic time slice shows what would be visible if all Neoproterozoic, Paleozoic, Mesozoic, and Cenozoic units were removed. 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 datasets also contains geological contacts, structural features, such as faults and shears, and miscellaneous supporting lines like crater impacts or structural grain within stratigraphic units.This is the second staged release of Geoscience Australia's national time based solid geology mapping program commenced under the Federal Government’s Exploring for the Future program. The Cenozoic time slice layer was extracted from Raymond, O.L., Liu, S., Gallagher, R., Highet, L.M., Zhang, W., 2012. Surface Geology of Australia, 1:1 000 000 scale, 2012 edition [Digital Dataset].

北澳大利亚克拉通1:100万比例尺固体地质数据集（第一版，2020年）是一套覆盖西澳大利亚州北部、北领地以及昆士兰州西北部的北澳大利亚克拉通无缝年代地层的（chronostratigraphic）固体地质数据集。该数据集通过有效剥离上覆覆盖层，对隐伏于覆盖层下的地层单元进行填图（Liu等，2015）。
该数据集包含五个年代地层时间切片，分别为新生代（Cenozoic）、中生代（Mesozoic）、古生代（Paleozoic）、新元古代（Neoproterozoic）以及新元古代前（Pre-Neoproterozoic）。举例如中生代时间切片（或地层图层），展示的是移除所有新生代地层单元后出露的中生代年龄地质体；新元古代前时间切片则展示移除所有新元古代、古生代、中生代及新生代地层单元后可见的地质体。
地质单元以多边形与线要素几何形式表达，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。该数据集还包含地质接触带、断层与剪切带等构造特征，以及诸如陨石撞击痕迹或地层单元内构造格架等辅助杂线要素。
本数据集是澳大利亚地质调查局（Geoscience Australia）国家时间序列固体地质填图项目的第二阶段发布成果，该项目由联邦政府未来勘探计划（Exploring for the Future）资助启动。其中新生代时间切片图层的数据源自Raymond、O.L.、Liu、S.、Gallagher、R.、Highet、L.M.、Zhang、W.于2012年发布的《澳大利亚地表地质1:100万比例尺2012版[数字数据集]》，由澳大利亚联邦堪培拉的澳大利亚地质调查局（Geoscience Australia）发布，且沿用了该数据集的数据架构。该图层的元数据可参考链接：https://pid.geoscience.gov.au/dataset/ga/74619。
