Renmark, Pata, Wanbi Gravity (P196163), 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 Renmark, Pata, Wanbi Gravity (P196163) contains a total of 160 point data values acquired at a spacing of 750 metres. The data is located in SA and were acquired in 1961, under project No. 196163 for Department of Mines and Energy South Australia (SADME).

重力数据用于表征地球表层下方岩石密度变化所引发的微小重力场变化。所采集的数据均通过标准流程处理，以确保记录得到的响应仅来源于地下岩石。经处理得到的数据集可通过解译揭示地下地质构造特征。经处理后的数据由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。本次伦马克（Renmark）、帕塔（Pata）、万比（Wanbi）重力数据集（编号P196163）共计包含160个测点数据，测点布设间距为750米。该数据集布设于南澳大利亚州（South Australia, SA），采集于1961年，由南澳大利亚州矿产与能源部（Department of Mines and Energy South Australia, SADME）依托196163号项目开展采集。
