Frome Downs Seismic, Gravity (P196942), 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 Frome Downs Seismic, Gravity (P196942) contains a total of 1518 point data values acquired at a spacing between 536 and 24135 metres. The data is located in SA and were acquired in 1970, under project No. 196942 for Crusader Oil 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由地下岩石引起。经处理得到的数据集可通过解译揭示地下地质构造。经处理的数据需经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。本次的Frome Downs地震与重力数据集（P196942）共计包含1518个测点数据，测点布设间距介于536米至24135米之间。该数据集采集于南澳大利亚州（South Australia, SA），采集工作于1970年开展，由Crusader Oil NL委托，项目编号为196942。
