Stavely Predrill Geophysics, Gravity (P201303), 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 Stavely Predrill Geophysics, Gravity (P201303) contains a total of 559 point data values acquired at a spacing between 50 and 200 metres. The data is located in VIC and were acquired in 2013, under project No. 201303 for Geoscience Australia.

重力数据用于监测地球表层下方岩石密度变化所引发的微小重力场扰动。所采集的数据将通过标准化流程进行处理，以确保记录到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，揭示地下地质构造特征。经处理后的数据将由澳大利亚地质调查局（Geoscience Australia，简称GA）的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。本斯塔夫利预钻探地球物理重力数据集（P201303）共计包含559组测点数据，测点间距介于50米至200米之间。该数据集采集于维多利亚州（Victoria，VIC），采集时间为2013年，隶属于澳大利亚地质调查局编号为201303的项目。
