Geophysical Survey Datasets - Gravity

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 with rigorous corrections 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.

重力数据用于测量因地球表层下方岩石密度变化引发的微小重力变化。所采集的数据将通过标准化方法开展处理，并施加严格校正，以确保记录得到的响应仅由地下岩石所致。经处理得到的数据集可通过解译，揭示地下地质构造。GA的地球物理学家会对处理后的数据进行质量核验，以确保GA发布的最终数据符合使用要求。
