Orange regolith landforms map

The 1:250 000 maps show the type and distribution of 51 regolith-landform unitswith unique dominant regolith-landform associations, and are a subset of the 205 mapping units on the six 1:100 000 maps. These units are distinct patterns ofrecurring landform elements with characteristic regolith associations.Geomorphic symbols indicate the location and type of geomorphic activity.The maps present a systematic analysis and interpretation of 1:89 000 scale 1973 RC9 aerial photography, 1:100 000 scale topographic maps (AUSLIG), and fieldmapping data.High resolution (250m line spacing) airborne gamma-ray spectrometry and magnetics(Geoterrex) were used where applicable

1:25万比例尺地图展示了51个带有独特优势风化壳-地貌组合（regolith-landform association）的风化壳-地貌单元（regolith-landform unit）的类型与分布，且该套地图是6幅1:10万比例尺地图上205个填绘单元的子集。这些单元是具备典型风化壳组合的反复出现的地貌要素的独特组合模式。地貌符号可指示地貌活动的位置与类型。本套地图基于1973年RC9航空摄影（比例尺1:89 000）、澳大利亚陆地信息集团（AUSLIG）发布的1:10万比例尺地形图以及野外填绘数据，完成了系统性分析与解译。在适用场景下，采用了线间距250米的高分辨率航空伽马能谱测量与航空磁法测量数据（Geoterrex提供）。
