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 Mt Isa B Gravity Bouguer Anomaly is a complete Bouguer anomaly grid for the Mt Isa 2006, Area B (P200641). This gravity survey was acquired under the project No. 200641 for the geological survey of QLD. The grid has a cell size of 0.0041 degrees (approximately 400m). The data are given in units of um/s^2, also known as 'gravity units', or gu. A total of 9857 gravity stations were acquired to produce this grid.
