Warrumbungle/Nandewar Ranges Volcano Gravity (P198202), 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 Warrumbungle/Nandewar Ranges Volcano Gravity (P198202) contains a total of 107 point data values acquired at a spacing of 3500 metres. The data is located in NSW and were acquired in 1982, under project No. 198202 for None.

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扰动。所采集的原始数据将通过标准化流程进行处理，以确保记录得到的响应仅源于地下岩石的重力效应。经处理后生成的数据集可通过解译，揭示地下地质构造特征。经处理的数据将由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要求。本次发布的沃伦本格尔/南迪瓦尔山脉火山重力数据集（P198202）共计包含107个测点数据，测点间距为3500米。该数据集采集于新南威尔士州（NSW），采集时间为1982年，隶属于编号为198202的项目，委托方信息未标注。
