Oodnadatta - SADM Road Gravity (P196664), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. This Oodnadatta - SADM Road Gravity (P196664) contains a total of 39 point data values acquired at a spacing between 2500 and 500 metres. The data is located in SA and were acquired in 1966, under project No. 196664 for Department of Mines and Energy South Australia (SADME).

重力数据可表征地球表层下方岩石密度变化所引发的微小重力场变动。所采集的原始数据将通过标准化处理流程进行处理，以确保所记录的响应仅源于地下岩石的影响。经处理得到的数据集可通过地质解译，揭示地下地质构造特征。GA（Geoscience Australia）的地球物理学家会对处理后的数据开展质量核查，以确保GA发布的最终数据符合使用需求。本奥当纳塔（Oodnadatta）- SADM公路重力数据集（编号P196664）共包含39个测点数据，测点间距介于2500米至500米之间。该数据集采集于南澳大利亚（South Australia，简称SA），于1966年依托南澳大利亚矿产与能源部（SADME）的196664号项目完成采集。
