Mildura detailed gravity (P198741), 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 Mildura detailed gravity (P198741) contains a total of 558 point data values acquired at a spacing between 100 and 1000 metres. The data is located in VIC and were acquired in 1987, under project No. 198741 for Department of Minerals and Energy (Victoria).

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。所采集的原始数据将通过标准流程开展处理，以确保记录得到的响应仅由地下岩石的密度变化所引起。经处理得到的数据集可通过解译，用以揭示地下地质构造特征。经处理的数据将由GA地球物理学家进行质量核验，以确保GA发布的最终数据满足实际使用需求。本次的米尔迪拉详细重力数据集（编号P198741）共包含558组测点数据，测点间距介于100米至1000米之间。该数据集的采集区域位于维多利亚州（VIC），采集工作于1987年实施，隶属于维多利亚州矿产与能源部的198741号项目。
