Alexander Creek Gravity (P196243), 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 Alexander Creek Gravity (P196243) contains a total of 477 point data values acquired at a spacing of 804 metres. The data is located in WA and were acquired in 1962, under project No. 196243 for Hawkestone Oil.

重力数据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。所采集的数据将通过标准化流程进行处理，以确保记录的响应仅源于地下岩石的影响。经处理后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。
