Gravity & Microgravity
Gravity surveying utilises the inherent density contrasts of different ground media to map near surface density anomalies. These anomalies may result from changes in overburden thickness, subsurface rock type, or features caused by air, water or sediment filled voids. These surveys are particularly useful in determining overburden thickness, mapping cavities (either natural or those caused by mining activities), and karst development.
