Alice Springs Area Gravity (P195911), 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 Alice Springs Area Gravity (P195911) contains a total of 47 point data values acquired at a spacing of 450 metres. The data is located in NT and were acquired in 1959, under project No. 195911 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变化。所采集的数据将通过标准处理流程进行加工，以确保记录的重力响应仅源自地下岩石。经处理后得到的数据集可通过解译揭示地下地质构造。经处理的数据会由GA地球物理学家开展质量核查，以确保GA发布的最终数据适配使用需求。本艾利斯斯普林斯区域重力数据集（编号P195911）共计包含47个点数据，采样间距为450米。该数据集的采集区域为北领地（NT），采集时间为1959年，隶属于矿产资源局（Bureau of Mineral Resources, BMR）编号为195911的项目。
