Coleraine Gravity (P196635), 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 Coleraine Gravity (P196635) contains a total of 180 point data values acquired at a spacing between 900 and 1800 metres. The data is located in VIC and were acquired in 1966, under project No. 196635 for Alliance Oil Development NL.

重力数据用于测量由地表以下岩石密度变化引起的重力微小变化。所采集的数据通过标准方法处理，以确保记录的响应仅源于地下岩石。处理结果生成的数据集可经解译以揭示地下地质结构。处理后的数据由GA地球物理学家进行质量检查，以确保GA发布的最终数据适用。
该Coleraine重力数据集（P196635）共包含180个点数据值，采集间距为900至1800米。数据位于VIC地区，于1966年采集，属于Alliance Oil Development NL的196635号项目。
