Plenty Dam, Gravity Survey NT 1988 (P198889), 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 Plenty Dam, Gravity Survey NT 1988 (P198889) contains a total of 471 point data values acquired at a spacing between 200 and 500 metres. The data is located in NT and were acquired in 1988, under project No. 198889 for CRA Exploration Pty Ltd.

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变化。所采集的数据均通过标准方法进行处理，以确保记录得到的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。经处理的数据由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。本次1988年北领地普拉蒂水坝重力测量（P198889）共包含471个测点数据，测点间距介于200米至500米之间。该数据集的采集区域为北领地（NT），采集工作于1988年在为CRA Exploration Pty Ltd实施的编号为198889的项目中完成。
