Maitland Region Gravity (P197566), 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 Maitland Region Gravity (P197566) contains a total of 626 point data values acquired at a spacing of 1500 metres. The data is located in SA and were acquired in 1975, under project No. 197566 for Department of Mines and Energy South Australia (SADME).

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变化。所采集的数据将采用标准处理流程开展处理，以确保所记录的重力响应仅由地下岩石引起。经处理得到的数据集可通过解译，用以揭示地下地质构造。经处理的数据会由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。本次的梅特兰地区重力数据集（编号P197566）共包含626个测点数据，测点间距为1500米。该数据集采集于南澳大利亚州（South Australia, SA），采集时间为1975年，隶属于南澳大利亚州矿业与能源部（Department of Mines and Energy South Australia, SADME）编号为197566的项目。
