Goonumbla detailed gravity - Narromine (P198034), 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 Goonumbla detailed gravity - Narromine (P198034) contains a total of 748 point data values acquired at a spacing between 500 and 600 metres. The data is located in NSW and were acquired in 1980, under project No. 198034 for Geopeko.

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。采集所得数据将通过标准流程开展处理，以确保所记录的重力响应仅由地下岩土引发。经处理得到的数据集可通过解译揭示地下地质构造特征。所有处理后的数据将由GA地球物理学家进行质量核验，以确保GA发布的最终数据满足使用要求。本次发布的古纳姆布拉（Goonumbla）精细化重力数据集——纳罗米奈（Narromine）（编号P198034）共包含748个测点数据，测点间距介于500米至600米之间。该数据集的采集区域位于新南威尔士州（New South Wales，NSW），采集工作于1980年开展，对应为Geopeko公司承接的编号198034项目。
