Alice Springs Gravity (P196113), 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 Gravity (P196113) contains a total of 163 point data values acquired at a spacing of 402 metres. The data is located in NT and were acquired in 1961, under project No. 196113 for Bureau of Mineral Resources (BMR).

重力数据用于量化地球表层下方岩石密度变化所引发的微小重力扰动。所采集的数据将通过标准化流程开展处理，以确保记录的重力响应仅源于地下岩石的影响。经处理得到的数据集可通过解译，用以揭示地下地质构造。经处理后的数据将由GA地球物理学家开展质量核验，以确保GA发布的最终数据满足使用需求。
本艾利斯斯普林斯重力数据集（P196113）共计包含163个测点数据，测点间距为402米。该数据集的测点分布于NT地区，于1961年依托矿产资源局（Bureau of Mineral Resources, BMR）编号196113的项目完成采集。
