Lake Hart Gravity (P197786), 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 Lake Hart Gravity (P197786) contains a total of 302 point data values acquired at a spacing of 100 metres. The data is located in SA and were acquired in 1977, under project No. 197786 for Solo Geophysics.

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场变化。所采集的数据将通过标准处理流程进行加工，以确保记录得到的响应仅由地下岩石引起。经处理后得到的数据集可通过地质解译，揭示地下的地质构造特征。经处理的数据将由GA地球物理学家开展质量校验，以确保GA发布的最终数据符合使用要求。本哈特湖重力数据集（Lake Hart Gravity，P197786）共计包含302个测点数据，采集间距为100米。该数据集采集于SA地区，采集工作于1977年开展，项目编号为197786，服务于Solo Geophysics公司。
