Broken Hill Gravity (P199428), 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 Broken Hill Gravity (P199428) contains a total of 3740 point data values acquired at a spacing between 30 and 240 metres. The data is located in NSW and were acquired in 1994, under project No. 199428 for CRA Exploration Pty Ltd.

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。所采集的数据将通过标准流程进行处理，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用于解译，以揭示地下地质构造。经处理的数据将由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。本次发布的布罗肯希尔重力数据集（P199428）共包含3740个测点数据，测点间距介于30米至240米之间。该数据集采集于新南威尔士州（NSW），于1994年为CRA勘探私人有限公司（CRA Exploration Pty Ltd）的199428号项目所采集。
