GRAVITY - Mines Ge ophysical

Gravity measurements are used to estimate the depths and geometry of sedimentary basins, to map major structures, to detect buried intrusions (some may have generated hydrothermal mineral deposits) and to investigate massive deposits (eg of iron ore). Most gravity measurements have been made on the ground, but airborne surveys are now common.

Geology, Prospecting and Exploration for Iron Ore Deposits ...

Exploitation of existing iron ore deposit is the easier part of the mining operations. The harder part is to find new ore deposits and to define their extent and the iron content (grade). Exploration is the process by which the accumulations of iron ore minerals can be found in the earth's crust.
