SA Gravity Survey 2003A10 (P200340), 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 Gravity Survey 2003A10 (P200340) contains a total of 209 point data values acquired at a spacing between 250 and 400 metres. The data is located in SA and were acquired in 2003, under project No. 200340 for None.

重力数据用于表征地球浅表下方岩石密度变化所引发的微小重力场变化。所采集的原始数据均通过标准化处理流程开展加工，以确保记录得到的重力响应仅源自地下岩石的物理效应。经处理生成的数据集可通过地质解译，揭示地下地质构造特征。经处理后的数据由GA地球物理学家开展质量核验，以保障GA发布的最终数据符合使用要求。本次南澳大利亚（South Australia）2003A10号重力测量项目（编号P200340）共包含209组测点数据，测点间距介于250米至400米之间。该数据集的采集点位分布于南澳大利亚境内，测量工作于2003年完成，隶属于编号为200340的项目，无委托方相关信息。
