SUMMARY
Gravity instruments, such as gravimeters, are utilized in airborne surveys to detect variations in the Earth's gravitational field, which indicate the presence of mineral or oil deposits beneath the surface. When an airplane equipped with these instruments flies over areas with significant density differences, such as mineral-rich deposits, the gravitational readings will show anomalies. These anomalies occur due to the centripetal force acting differently over denser or less dense materials compared to the surrounding terrain. Understanding these gravitational variations is crucial for mineral exploration and resource management.
