magnetic surveys

Magnetic surveys are a geological exploration method used to measure variations in the Earth's magnetic field. By using sensitive instruments, surveyors detect the magnetic signatures of different rock types and mineral deposits underground. This data helps identify locations where valuable resources like minerals or oil might be found. The surveys are non-invasive and can cover large areas, making them efficient for mapping subsurface features. They are commonly used in mineral exploration, archaeology, and environmental studies, providing valuable information without the need for extensive drilling or excavation.
