Albany Fraser Gravity Survey (P201062), 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 Albany Fraser Gravity Survey (P201062) contains a total of 9258 point data values acquired at a spacing of 2500 metres. The data is located in WA and were acquired in 2010, under project No. 201062 for Department of Industry and Resources (Western Australia).重力数据用于表征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。 本次奥尔巴尼-弗雷泽重力测量项目（编号：P201062）共计包含9258个测点数据，测点间距为2500米。该数据的采集区域位于西澳大利亚州（WA），采集工作于2010年完成，隶属于西澳大利亚州工业与资源部立项的编号为201062的项目。
