Cooper Basin Seismic, Gravity (P196743), 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 Cooper Basin Seismic, Gravity (P196743) contains a total of 1889 point data values acquired at a spacing between 600 and 800 metres. The data is located in QLD, SA and were acquired in 1967, under project No. 196743 for Delhi Petroleum Pty Ltd.

重力数据用于测量因地球表层下方岩石密度变化所引发的微小重力场变化。所采集的数据将通过标准流程进行处理，以确保记录的响应仅源于地下岩石的密度变化。经处理后得到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。本次发布的库珀盆地（Cooper Basin）地震与重力数据集（编号P196743）共包含1889个测点数据，测点间距介于600至800米之间。该数据集的采集区域覆盖昆士兰州（QLD）与南澳大利亚州（SA），采集工作于1967年开展，由德里石油私人有限公司（Delhi Petroleum Pty Ltd）委托实施，项目编号为196743。
