Andean geology is the study of the geology of the Andes mountain range, which is one of the longest and highest mountain ranges in the world, spanning several countries in South America including Argentina, Bolivia, Chile, Colombia, Ecuador, and Peru. This research area focuses on understanding the geological processes that have shaped the Andes, including tectonic plate movements, mountain building, volcanic activity, and erosion. Researchers in Andean geology study the diverse rock formations, mineral deposits, and seismic activity in the region to gain insight into the geological history and evolution of the Andes. This field of study also plays a crucial role in understanding natural hazards such as earthquakes, landslides, and volcanic eruptions in the Andes region.
