SA Detailed Gravity Survey 85E4 (P198554), 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 85E4 (P198554) contains a total of 55 point data values acquired at a spacing of 165 metres. The data is located in SA and were acquired in 1985, under project No. 198554 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变化。采集所得的数据将通过标准方法进行处理，以确保记录得到的重力响应仅由地下岩石引起。经处理得到的数据集可通过解译，用以揭示地下地质构造。经处理的数据将由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。本次南澳大利亚州（South Australia）详细重力测量项目85E4（编号P198554）共包含55个测点数据，测点间距为165米。该数据集采集于南澳大利亚州，采集时间为1985年，隶属于编号198554项目，无委托方。
