SA Detailed Gravity Survey 1996A4 (P199654), 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 SA Detailed Gravity Survey 1996A4 (P199654) contains a total of 334 point data values acquired at a spacing of 500 metres. The data is located in SA and were acquired in 1996, under project No. 199654 for None.

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变化。所采集的数据将通过标准化流程进行处理，以确保记录的响应仅由地下岩石引起。经处理得到的数据集可通过解译，揭示地下地质构造。处理后的数据将由GA地球物理学家开展质量核查，以确保GA发布的最终数据符合使用要求。本数据集为1996年A4版南澳大利亚（South Australia，简称SA）详细重力测量数据集（编号P199654），共包含334个测点数据值，测点间距为500米。该数据采集于SA境内，采集时间为1996年，隶属于编号199654的项目，无指定委托方。
