Gravity & Magnetic Survey

Gravity and Magnetic Surveys are geophysical exploration techniques used to measure variations in the Earth’s gravitational and magnetic fields. These variations are caused by differences in subsurface density and magnetic properties of rocks and minerals. By analyzing these subtle changes, valuable insights into underground structures and composition can be obtained.

In a gravity survey, highly sensitive instruments called gravimeters measure minute differences in gravitational pull across a survey area, which helps identify density variations such as voids, basins, or dense mineral bodies. Magnetic surveys, on the other hand, use magnetometers to detect changes in the Earth’s magnetic field caused by magnetic minerals in the subsurface. These measurements can be collected from ground-based systems, airborne platforms, or drones, depending on the scale and requirements of the project.

Gravity and Magnetic Surveys are widely used in mineral exploration, oil and gas prospecting, and geological mapping. They are particularly effective for identifying ore bodies, fault lines, and large-scale geological structures. As non-invasive and cost-effective methods, these surveys provide essential preliminary data that supports further detailed investigations and informed decision-making.
