Healesville detailed gravity (P198844), 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 Healesville detailed gravity (P198844) contains a total of 69 point data values acquired at a spacing between 100 and 700 metres. The data is located in VIC and were acquired in 1988, under project No. 198844 for Department of Minerals and Energy (Victoria).

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动。所采集的数据将通过标准化处理流程进行加工，以确保所记录的响应仅源于地下岩石。经处理生成的数据集可通过解译，揭示地下地质构造。处理后的数据将由GA地球物理学家开展质量核验，以保障GA发布的最终数据符合预定使用要求。本次希勒斯维尔（Healesville）精细化重力数据集（编号P198844）共包含69组测点数据，测点间距介于100米至700米之间。该数据集的采集区域位于VIC（Victoria），采集工作于1988年依托维多利亚州矿产与能源部的198844号项目完成。
