Shell Coal Gravity - Southwest WA (P198149), 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 Shell Coal Gravity - Southwest WA (P198149) contains a total of 2569 point data values acquired at a spacing between 1600 and 1900 metres. The data is located in WA and were acquired in 1981, under project No. 198149 for Shell Australia Pty Ltd.重力数据用于测量地球地表下方岩石密度变化所引发的微小重力变化。采集得到的原始数据将通过标准化流程进行处理，以确保记录的重力响应仅源于地下岩石的影响。经处理得到的数据集可通过解译，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。本数据集为西南澳大利亚壳牌煤炭重力数据集（Shell Coal Gravity - Southwest WA，编号P198149），共包含2569个测点数据，测点间距介于1600米至1900米之间。该数据采集于西澳大利亚州（Western Australia，简称WA），采集时间为1981年，相关项目编号为198149，由壳牌澳大利亚私人有限公司委托开展。
