EL2475 Wigetty prospect Mulgathing, SA Detailed Gravity Survey (P200276), 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 EL2475 Wigetty prospect Mulgathing, SA Detailed Gravity Survey (P200276) contains a total of 453 point data values acquired at a spacing between 50 and 250 metres. The data is located in SA and were acquired in 2002, under project No. 200276 for Iluka Resources Ltd.

重力数据用于观测地球表层下方岩石密度变化所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，确保记录的重力响应仅源于地下岩石的重力效应。经处理后生成的数据集可通过地质解译，用以揭示地下地质构造特征。经处理的数据将由GA地球物理学家进行质量核验，以保障GA发布的最终数据符合实际使用需求。本次编号为EL2475的南澳大利亚州（SA）穆加辛（Mulgathing）地区威格蒂（Wigetty）勘探区详细重力测量项目（项目编号：P200276）共包含453个测点数据，测点间距介于50米至250米之间。该数据集采集工作于2002年开展，由伊鲁卡资源有限公司（Iluka Resources Ltd）承接编号为200276的项目完成作业。
