Eganu Gravity (P196242), 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 Eganu Gravity (P196242) contains a total of 201 point data values acquired at a spacing of 804 metres. The data is located in WA and were acquired in 1962, under project No. 196242 for West Australian Petroleum Pty Ltd.

重力数据用于测量地球表层下方岩石密度变化引发的微小重力场变动。所采集的数据将通过标准化流程处理，以确保记录的响应仅来源于地下岩石。经处理得到的数据集可通过解译揭示地下地质构造。GA地球物理学家会对处理后的数据开展质量核验，以确保GA发布的最终数据符合使用要求。本次伊加努重力数据集（Eganu Gravity，编号P196242）共计包含201个测点数据，测点布设间距为804米。该数据集采集区域位于西澳大利亚州（WA），采集工作于1962年开展，由西澳石油私人有限公司（West Australian Petroleum Pty Ltd）委托的196242号项目执行。
