Casterton Coleraine Infill (P199630), 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 Casterton Coleraine Infill (P199630) contains a total of 506 point data values acquired at a spacing between 1000 and 2000 metres. The data is located in SA, VIC and were acquired in 1996, under project No. 199630 for None.

重力数据用于表征地球表面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化流程进行处理，以确保记录得到的响应仅源自地下岩石的重力影响。经处理后生成的数据集可通过地质解译揭示地下地质构造特征。经处理的数据将由GA地球物理学家开展质量核查，以保障GA发布的最终数据符合使用要求。本次卡斯特顿-科莱恩填图数据集（Casterton Coleraine Infill，项目编号P199630）共计包含506个测点数据，测点间距介于1000米至2000米之间。该数据集采集区域覆盖南澳大利亚州（South Australia，简称SA）与维多利亚州（Victoria，简称VIC），采集工作于1996年开展，依托项目编号199630实施，无指定委托方。
