P201631 Stavely Gravity Traverses CSCBA267GU

Gravity data measure 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 P201631 Stavely Gravity Traverses CSCBA267GU is a complete spherical cap Bouguer anomaly grid for the Stavely Gravity Traverses, 2016 (P201631). This gravity survey was acquired under the project No. 201631 for the geological survey of VIC. The grid has a cell size of 0.0005 degrees (approximately 50m). The data are given in units of um/s^2, also known as 'gravity units', or gu. A total of 3564 gravity stations were acquired to produce this grid.

重力数据用于测量地球表层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流程进行处理，确保记录的响应仅源于地下岩石的影响。由此生成的数据集可通过解译揭示地下地质构造。经处理的数据将由GA地球物理学家进行质量校验，以确保GA发布的最终数据满足使用需求。
本次编号为P201631的Stavely重力测线数据集（CSCBA267GU），为2016年Stavely重力测线项目（P201631）的完整球冠布格异常（spherical cap Bouguer anomaly）网格数据。本次重力测量由维多利亚州（VIC）地质调查局依托编号为201631的项目实施。该网格的单元格尺寸为0.0005度（约合50米）。数据单位为微米每二次方秒（μm/s²），又称重力单位（gravity units），缩写为gu。本次网格数据共采集自3564个重力测点（gravity stations）。
