Crustal mapping is a research area that involves studying and mapping the composition and structure of Earth's crust. This includes mapping the distribution of rocks, minerals, faults, and other geological features at the surface and subsurface level. Crustal mapping is important for understanding the geology of an area, identifying potential mineral deposits or natural resources, and assessing seismic hazards. Advanced technologies such as satellite imagery, geophysical surveys, and remote sensing are often used in crustal mapping studies.
