Cobar-Moree-Gwydir River Gravity (P196357), 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 Cobar-Moree-Gwydir River Gravity (P196357) contains a total of 187 point data values acquired at a spacing of 3200 metres. The data is located in NSW and were acquired in 1963, under project No. 196357 for Department of Mines (New South Wales).

重力数据用于表征地球表面下方岩石密度变化引发的微小重力场变化。所采集的数据将通过标准化流程处理，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通过解译，揭示地下地质构造特征。经处理的数据将由GA地球物理学家开展质量核验，以确保GA发布的最终数据满足使用要求。本次的科巴-莫里-吉迪尔河重力数据集（P196357）共包含187个测点数据，测点间距为3200米。该数据集的测点分布于新南威尔士州（New South Wales），采集工作于1963年开展，隶属于新南威尔士州矿产部（Department of Mines (New South Wales)）的第196357号项目。
