Geophysical constraints refer to the physical properties and processes of the Earth's structure that influence the behavior and distribution of geological materials. This includes factors such as gravity, magnetism, seismic waves, and electromagnetic fields, which can provide valuable information about the composition, structure, and dynamics of the Earth's interior. Geophysical constraints are widely used in various fields of research, including exploration for natural resources, monitoring of earthquakes and volcanic activity, and studying the tectonic processes that shape the Earth's surface. By analyzing and interpreting geophysical data, researchers can gain insights into the Earth's subsurface properties and better understand the complex interactions that drive geological processes.
