Find Caverns And Base Metals With Gravity Surveys

What are gravity surveys?

Gravity surveys are a passive potential field method that measures variations in the earth’s gravitational field. These variations are the result of changes in the subsurface density distribution of rocks and minerals. Gravity data requires careful data reduction procedures to remove influencing factors such as the earth’s ellipticity, lunar tidal forces and local geographic effects. After corrections have been made, subtle features can be identified in the data.

Identify Mineral Deposits

Key Features And Benefits Of Gravity Surveys

Indicate Regions Of Mass Excess Or Mass Deficiency

A region of mass excess could be caused by the presence of base metals (high density) while a region of mass deficiency could be caused by voids or graphite (low density)

Detailed Subsurface Mapping

Density distribution gives information on the subsurface geology

Mineral Deposit Identification

Used to map variation in density of mineral deposits such as volcanogenic massive sulfides and kimberlites

Identifies Subsurface Caverns

Avoid hazardous zones in mining operations or assess the risk of ground subsidence
