Geology of the Donors Hill

These data are a digital representation of information depicted on the printed map of the Donors Hill 1:250 000 Geological Series produced by AGSO and the Geological Survey of Queensland (GSQ) in 1972 (1st edition).Data present include geological polygons (litho-stratigraphic units), linear structural features (faults, dykes, folds, trends, lineaments etc), and point features (mines, structural points etc). Polygons have a range of attributes extracted from each individual map including unit name, age and lithological description, while lines and points are feature coded according to the AGSO publication 'Symbols Used On Geological Maps' (BMR 1989). A standard look-up table of AGSO geological codes and associated descriptions is available (see ADDITIONAL METADATA).The data has gradually evolved from elementary CAD quality data into its present topologically structured GIS format, and hence has many imperfections and inconsistencies. Data has undergone rigorous validation and testing that includes over 80 different tests. See ADDITIONAL METADATA for more information on the data standards used.

本数据集为1972年由澳大利亚地质科学局（AGSO）与昆士兰州地质调查局（GSQ）编制的第一版《多诺斯山1:25万地质系列图》印刷图件所载信息的数字化再现。所含数据包括地质多边形（岩性地层单元）、线性构造要素（断层、岩脉、褶皱、构造走向、线性构造等）以及点要素（矿山、构造点位等）。多边形要素附带从单幅图件中提取的多类属性字段，包括单元名称、形成年代与岩性描述；而线要素与点要素则依据AGSO发布的《地质图图式》（BMR 1989）进行要素编码。本数据集附带AGSO地质编码及对应描述的标准查询表（详见附加元数据）。本数据集从最初的基础计算机辅助设计（CAD）级数据逐步演进至当前的拓扑结构化地理信息系统（GIS）格式，因此存在诸多不完善之处与不一致性。数据集已通过包含80余项不同测试的严格验证与检验。有关本数据集所采用的数据标准的更多信息，请详见附加元数据。
