Parkes-Narromine Gravity (P196818), 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 Parkes-Narromine Gravity (P196818) contains a total of 151 point data values acquired at a spacing between 5000 and 10000 metres. The data is located in NSW and were acquired in 1968, under project No. 196818 for None.

重力数据用于表征地球表层下方岩石密度变化引发的微小重力场扰动。所采集的原始数据将通过标准处理流程开展校正，以确保记录的重力响应仅源自地下岩石的影响。经处理得到的数据集可通过地质解译，揭示地下区域的地质构造特征。经处理的数据需由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。本次的帕克斯-纳罗明重力数据集（Parkes-Narromine Gravity，编号P196818）共计包含151组测点数据，测点间距介于5000至10000米之间。该数据集采集于新南威尔士州（New South Wales），于1968年通过编号为196818的项目完成野外数据采集，委托方信息未标注。
