Geraldton-Carnarvon, Canning Basin Gravity (P195307), 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 Geraldton-Carnarvon, Canning Basin Gravity (P195307) contains a total of 1 point data values acquired at a spacing between 402 and 8045 metres. The data is located in WA and were acquired in 1953, under project No. 195307 for Bureau of Mineral Resources (BMR).

重力数据用于测量因地球地表下方岩石密度变化所引发的微小重力场变化。所采集的重力数据均通过标准流程进行处理，以确保记录得到的重力响应仅由地下岩石引起。经处理后得到的数据集可通过解译以揭示地下地质构造。经处理后的数据由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。本杰拉尔顿-卡那封地区坎宁盆地重力数据集（P195307）共包含1个测点数据，测点采集间距介于402米至8045米之间。该数据的采集区域位于西澳大利亚州（Western Australia, WA），采集工作于1953年开展，隶属于矿产资源局（Bureau of Mineral Resources, BMR）编号为195307的项目。
