Murray Basin - Depth To Basement (1:1,000,000)

The polygons represent the depth from the surface to the Palaeozoic bedrock. The polygon data was constructed using the depth to basement contours at 50m interval generated from both drill hole data, and depth to magnetic source estimates. For detailed methodology refer to Gold Undercover report 21 - Depth to Palaeozoic basement of the Gold Undercover region using borehole and magnetic data.本数据集的多边形要素表征地表至古生代基岩（Palaeozoic bedrock）的埋藏深度。该多边形数据集基于钻孔数据与磁源埋藏深度估算结果生成的50米间隔基底等值线构建而成。详细研究方法可参阅《Gold Undercover》第21号报告：《基于钻孔与磁数据的Gold Undercover区域古生代基底埋藏深度》。
