Iron Knob, Port Augusta, Whyalla - SADM Road Gravity (P196764), 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 Iron Knob, Port Augusta, Whyalla - SADM Road Gravity (P196764) contains a total of 21 point data values acquired at a spacing between 4750 and 5500 metres. The data is located in SA and were acquired in 1967, under project No. 196764 for Department of Mines and Energy South Australia (SADME).

重力数据用于测量地球表层下方岩石密度变化所引发的微小重力场变化。所采集的原始数据将通过标准化流程开展处理，以确保记录得到的重力响应仅由地下岩石的密度变化引起。经处理后的数据集可通过地质解译，揭示地下地质构造特征。处理后的数据需由GA地球物理学家进行质量核验，以确保GA发布的最终数据满足使用需求。本次公开的艾恩诺布、奥古斯塔港、怀阿拉——SADM道路重力测量数据集（P196764）共包含21个测点数据，测点布设间距介于4750米至5500米之间。该数据集采集于南澳州（SA），完成于1967年，隶属于南澳州矿产与能源部（Department of Mines and Energy South Australia，缩写SADME）编号为196764的项目。
