Mt Painter, Tasmania Gravity Survey, 2008 (P200878), 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 Mt Painter, Tasmania Gravity Survey, 2008 (P200878) contains a total of 1823 point data values acquired at a spacing between 100 and 500 metres. The data is located in TAS and were acquired in 2008, under project No. 200878 for Sinosteel Australia Pty Ltd.

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扰动。所采集的原始数据将通过标准化流程开展处理，确保记录得到的响应仅由地下岩石的密度变化引起。经处理生成的数据集可通过地质解译，揭示地下地质构造特征。处理后的数据将由GA地球物理学家进行质量核验，以保障GA发布的最终数据满足使用需求。本项2008年塔斯马尼亚州派恩特山重力测量项目（编号P200878）共计获取1823组测点数据，测点间距介于100米至500米之间。该数据的采集区域位于塔斯马尼亚州（TAS），采集工作于2008年完成，项目编号为200878，服务方为中钢澳大利亚私人有限公司（Sinosteel Australia Pty Ltd）。
