AFGN Absolute Riverina Gravity Survey (P201390), 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 AFGN Absolute Riverina Gravity Survey (P201390) contains a total of 6 point data values acquired at a spacing of 750 metres. The data is located in NSW, VIC and were acquired in 2013, under project No. 201390 for Geoscience Australia.

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处理流程进行校正，以确保记录得到的响应仅来源于地下岩石的密度变化。经处理后生成的数据集可通过解译分析，用以揭示地下地质构造特征。经处理的数据将由澳大利亚地球科学局（Geoscience Australia，简称GA）的地球物理学家开展质量核验，以确保该局发布的最终数据满足使用需求。
本次AFGN绝对里弗赖纳重力测量项目（编号P201390）共包含6组测点数据，测点布设间距为750米。该数据集的采集区域涵盖新南威尔士州（NSW）与维多利亚州（VIC），由澳大利亚地球科学局于2013年依托编号为201390的项目完成采集。
