Victoria Basin Gravity Survey (P201582), 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 NTGS Victoria Basin Gravity Survey (P201582) contains a total of 6172 point data values acquired at a spacing of 4000 metres. The data is located in NT and were acquired in 2015, under project No. 201582 for Northern Territory of Australia (Northern Territory Geological Survey).

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。所采集的原始数据均采用标准化流程进行处理，以确保记录的重力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。处理后的数据由GA地球物理学家开展质量核验，以确保GA发布的最终数据符合使用要求。本次北领地地质调查局（Northern Territory Geological Survey，NTGS）维多利亚盆地重力测量项目（编号P201582）共计包含6172个测点数据，测点间距为4000米。该数据分布于澳大利亚北领地境内，采集工作于2015年开展，所属项目编号为201582，服务于澳大利亚北领地地质调查局。
