Blackall-Barcaldine Gravity (P196550), 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 Blackall-Barcaldine Gravity (P196550) contains a total of 4765 point data values acquired at a spacing between 100 and 700 metres. The data is located in QLD and were acquired in 1965, under project No. 196550 for American Overseas Petroleum.

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验，以确保GA发布的最终数据符合使用要求。本次的布莱克奥尔-巴卡尔丁重力数据集（Blackall-Barcaldine Gravity，编号P196550）共包含4765个测点数据，测点间距介于100米至700米之间。该数据集采集于昆士兰州（QLD），完成于1965年，隶属于为美国海外石油公司开展的编号196550项目。
