SA Semi-Detailed Gravity Survey 93A5 (P199375), 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 Semi-Detailed Gravity Survey 93A5 (P199375) contains a total of 239 point data values acquired at a spacing of 1000 metres. The data is located in SA and were acquired in 1993, under project No. 199375 for None.重力数据可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。所采集的数据将通过标准处理流程进行加工，以确保记录的重力响应仅由地下岩石引发。经处理得到的数据集可通过解译，用以揭示地下地质构造。由GA（Geoscience Australia）地球物理学家对处理后的数据开展质量核查，以确保GA发布的最终数据均符合预期使用要求。本次南澳大利亚州（South Australia，简称SA）半详细重力测量93A5（项目编号P199375）共包含239个测点数据，测点间距为1000米。该数据采集于南澳大利亚州，采集时间为1993年，隶属于项目编号199375，无明确委托方。
