Ouyen Region Gravity (P198842), 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 Ouyen Region Gravity (P198842) contains a total of 840 point data values acquired at a spacing between 400 and 1500 metres. The data is located in VIC and were acquired in 1988, under project No. 198842 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引发的微小重力场变化。所采集的原始数据均通过标准流程开展处理，以确保记录的重力响应仅源于地下岩石的影响。经处理得到的数据集可通过解译揭示地下地质构造特征。经处理后的数据由澳大利亚地球科学局（GA，Geoscience Australia）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。本乌延地区重力数据集（编号P198842）共包含840个测点数据，测点布设间距介于400米至1500米之间。该数据集的采集区域位于维多利亚州（VIC，Victoria），采集工作于1988年开展，隶属于维多利亚州矿产与能源部编号为198842的项目。
