Heywood Gravity on Seismic Surv OGF92B (P199330), 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 Heywood Gravity on Seismic Surv OGF92B (P199330) contains a total of 732 point data values acquired at a spacing of 200 metres. The data is located in VIC and were acquired in 1993, under project No. 199330 for Geological Survey of Victoria (GSV).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，以确保记录得到的重力响应仅由地下岩石引发。经处理得到的数据集可通过解译揭示地下地质构造。 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。 本数据集为对应地震勘探OGF92B（P199330）的Heywood重力数据，共包含732组测点数据，测点间距为200米。该数据采集于维多利亚州（VIC），采集时间为1993年，隶属于维多利亚地质调查局（Geological Survey of Victoria, GSV）编号为199330的项目。
