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.

该多边形图层表征地表至古生代基岩的埋藏深度。本多边形数据集以钻孔数据与磁源埋深估算结果为基础，生成间隔为50米的基岩埋深等值线后构建而成。如需了解详细方法，请参阅《Gold Undercover报告21——基于钻孔与磁测数据的Gold Undercover区域古生代基岩埋深》。
