Gap Filling Gravity Putty (P198101), 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 Gap Filling Gravity Putty (P198101) contains a total of 10 point data values acquired at a spacing between 500 and 6000 metres. The data is located in NSW and were acquired in 1981, under project No. 198101 for None.

重力数据用于量化地球表层下方岩石密度变化所引发的微小重力场扰动。所采集的数据将通过标准处理流程开展加工，以确保所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地质解译，揭示地下地质构造。处理后的数据将由GA地球物理学家进行质量核验，以保障GA发布的最终数据满足使用需求。本次公开的间隙填补型重力数据集（Gap Filling Gravity Putty，编号P198101）共计包含10组测点数据，测点间距介于500米至6000米之间。该数据集采集于新南威尔士州（New South Wales，NSW），于1981年依托编号为198101的项目完成，委托方信息未标注。
