Bedrock Geology of Queensland and northwest New South Wales

The 1:2 500 000 scale bedrock geology map of Queensland and northwest New South Wales was compiled at 1:500 000 scale, primarily based on the 1:2 000 000 surface geology map of Queensland Geology (2012) by removing unconsolidated Cenozoic sediments with interpretation of aeromagnetic data and reference to Geological Survey of New South Wales' interpretation of the Thomson Orogen region (Hegarty 2010). This work also referred to the geological province work by Stewart et al (2013). Stratigraphic unit definition data is linked to the Australian Stratigraphic Names Database through the stratno, by which this bedrock geology map may also be linked to other geoscientific databases housed in Geoscience Australia.

昆士兰州与新南威尔士州西北部的1:250万比例尺基岩地质图（bedrock geology map），系以1:50万比例尺的编绘精度完成缩编，核心编制依据为2012年发布的《昆士兰州地表地质图》（1:200万比例尺）。编绘过程中，通过解译航空磁测数据（aeromagnetic data）移除了未固结的新生代沉积物（Cenozoic sediments），并参考了新南威尔士州地质调查局（Geological Survey of New South Wales）对汤姆森造山带区域（Thomson Orogen region）的解译成果（Hegarty 2010）。本研究同时参考了Stewart等人2013年开展的地质省域区划相关研究工作。地层单元（Stratigraphic unit）定义数据通过stratno字段与澳大利亚地层名称数据库（Australian Stratigraphic Names Database）建立关联，借此该基岩地质图亦可与澳大利亚地球科学局（Geoscience Australia）所托管的其他地球科学数据库实现关联。
