Legune Seismic, Gravity, Seismic Refraction Survey (P196448), 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 Legune Seismic, Gravity, Seismic Refraction Survey (P196448) contains a total of 410 point data values acquired at a spacing of 531 metres. The data is located in NT and were acquired in 1964, under project No. 196448 for Australian Aquitaine Petroleum Pty Ltd.

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变动。所采集的数据均通过标准流程处理，以确保记录的响应仅由地下岩石引发。经处理得到的数据集可通过解译揭示地下地质构造。经处理的数据将由GA地球物理学家开展质量核查，以保障GA发布的最终数据符合使用需求。本次Legune地震、重力及地震折射勘探（P196448）共计包含410组测点数据，测点间距为531米。该勘探数据采集于北领地（Northern Territory，NT），于1964年在编号为196448的项目中完成，委托方为澳大利亚阿基坦石油私人有限公司（Australian Aquitaine Petroleum Pty Ltd）。
