North West Rosedale Gravity (P195107), 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 North West Rosedale Gravity (P195107) contains a total of 235 point data values acquired at a spacing of 750 metres. The data is located in VIC and were acquired in 1951, under project No. 195107 for Bureau of Mineral Resources (BMR).

重力数据（Gravity data）用于测量地球表层下方岩石密度变化所引发的微小重力变化。所采集的数据将通过标准流程处理，以确保记录得到的响应仅源于地下岩石。经处理后生成的数据集可通过解译，揭示地下地质构造。经处理后的数据由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。本西北罗塞代尔重力数据集（North West Rosedale Gravity, P195107）共包含235个测点数据，采集间距为750米。该数据集位于维多利亚州（VIC），采集于1951年，隶属于矿产资源局（Bureau of Mineral Resources, BMR）的195107号项目。
