Nucha Gravity (P196530), 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 Nucha Gravity (P196530) contains a total of 400 point data values acquired at a spacing of 1609 metres. The data is located in NSW and were acquired in 1965, under project No. 196530 for Planet Explor Co P/L.

重力数据用于探测地球表层下方岩石密度变化引发的微小重力场变化。所采集的数据将通过标准化流程进行处理，以确保记录的响应仅源于地下岩石的影响。经处理后得到的数据集可通过解译揭示地下地质构造。经处理的数据将由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。本努查重力数据集（Nucha Gravity，编号P196530）共包含400个测点数据，测点间距为1609米。该数据集采集于新南威尔士州（New South Wales），采集时间为1965年，所属项目编号为196530，委托方为Planet Explor Co P/L。
