John Suppe, Jonny Wu and Yi-Wei Chen (shown from left to right) are co-authors on a recent Nature paper about the formation of the Andean mountain … The Andean mountain system is the result of global plate-tectonic forces during the Cenozoic Era (roughly the past 65 million years) that built upon earlier geologic activity. Dr Evenstar said: "It seems highly likely that the Andes have gone up slowly over at least the last 30 million years, and are the result of gradual thickening of the crust. Fold mountains are the most common type of mountain in the world. Plate-tectonics study could explain why some mountains are higher than expected.
