Blackstone WA Gravity Survey (P200663), 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 Blackstone WA Gravity Survey (P200663) contains a total of 309 point data values acquired at a spacing between 2000 and 3000 metres. The data is located in WA and were acquired in 2006, under project No. 200663 for None.

重力数据可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。所采集的数据将按照标准流程进行处理，以确保记录得到的响应仅源于地下岩石的影响。经处理后得到的数据集可通过解译，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验，以确保GA发布的最终数据符合使用要求。本次布莱克斯顿西澳大利亚州（Western Australia，缩写WA）重力测量项目（Blackstone WA Gravity Survey，编号P200663）共包含309个测点数据，测点间距介于2000米至3000米之间。该数据集的采集区域位于西澳大利亚州，于2006年完成数据采集，对应项目编号为200663，委托方信息未标注。
