Thunda Gravity (P196735), 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 Thunda Gravity (P196735) contains a total of 135 point data values acquired at a spacing between 1000 and 9000 metres. The data is located in QLD and were acquired in 1967, under project No. 196735 for Alliance Oil Development NL.

重力数据用于监测地球表层下方岩石密度变化引发的微小重力场变化。所采集的重力数据将通过标准处理流程进行校正，以确保记录得到的重力响应仅由地下岩石所引发。经处理得到的数据集可通过地质解译揭示地下地质构造特征。经处理后的数据集将由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实际应用需求。本次公开的Thunda重力数据集（P196735）共包含135个测点数据，测点布设间距介于1000米至9000米之间。该数据集采集区域位于昆士兰州（QLD），于1967年依托编号为196735的项目为Alliance Oil Development NL公司完成野外数据采集工作。
