Boulia-Longreach-Windorah-Toko Gravity (P195805), 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 Boulia-Longreach-Windorah-Toko Gravity (P195805) contains a total of 569 point data values acquired at a spacing between 1000 and 8000 metres. The data is located in QLD and were acquired in 1958, under project No. 195805 for Bureau of Mineral Resources (BMR).

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扰动。所采集的数据将通过标准化流程进行处理，以确保记录的重力响应仅由地下岩石的密度变化引起。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发布的最终数据满足使用需求。本次的Boulia-Longreach-Windorah-Toko重力数据集（P195805）共计包含569组测点数据，测点间距介于1000米至8000米之间。该数据集的采集区域位于昆士兰州（QLD），于1958年由矿产资源局（Bureau of Mineral Resources, BMR）依托编号为195805的项目完成采集工作。
