What is remote geochemistry?

Remote geochemistry is the study and analysis of the Earth's chemical composition and processes using remote sensing technologies, such as satellite imagery, aerial sensors, or drones. This field allows scientists to gather geochemical data from inaccessible or large areas without direct sampling. Remote geochemistry is commonly used in mineral exploration, environmental monitoring, and planetary science. It supports efficient, large-scale assessments while reducing time and costs compared to traditional fieldwork.
