Gravity Surveys : Basic Principles, Applications of

Gravity surveys are geophysical techniques used to measure the variations in the Earth's gravitational field at different locations. These surveys involve the measurement of the gravitational acceleration at the Earth's surface, typically expressed in terms of milligals (mGal) or microgals (μGal). The purpose of gravity surveys is to map and understand the distribution of …
