South Yilgarn Gravity Survey, WA, 2009 (P200961), 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 South Yilgarn Gravity Survey, WA, 2009 (P200961) contains a total of 6125 point data values acquired at a spacing of 2500 metres. The data is located in WA and were acquired in 2009, under project No. 200961 for Department of Industry and Resources (Western Australia).

重力数据（Gravity data）用于测量地球表层下方岩石密度变化所引发的微小重力变动。所采集的数据需通过标准方法进行处理，以确保记录得到的响应仅由地下岩石引起。经处理后得到的数据集可通过解译揭示地下地质构造。处理后的数据需由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。本数据集为2009年西澳大利亚州南伊尔贡重力测量项目（P200961），共计包含6125个点数据值，采集间距为2500米。该数据采集于西澳大利亚州，采集时间为2009年，隶属于编号为200961的项目，由西澳大利亚州工业与资源部（Department of Industry and Resources, Western Australia）负责实施。
