The study, published in the journal Nature Geoscience, used cosmic ray exposure dating to measure the uplift rates of four mountain peaks in the Swiss Alps. Cosmic ray exposure dating is a technique that uses the amount of cosmic radiation that a rock has been exposed to to determine its age.
The researchers found that the four peaks were rising at an average rate of 1.2 millimeters per year. This rate is faster than the rate of erosion, which is estimated to be about 0.5 millimeters per year.
The study's findings have implications for understanding the long-term evolution of the Alps. The Alps are one of the most rapidly eroding mountain ranges in the world, and it was thought that erosion was outpacing uplift. However, the new study shows that uplift is actually outpacing erosion, which means that the Alps will continue to rise in the future.
The study also has implications for understanding the impact of climate change on the Alps. Climate change is causing the glaciers in the Alps to melt, which is reducing the amount of ice that weighs down the mountains. This could cause the Alps to rise even faster in the future.
"Our findings show that the Alps are a dynamic mountain range that is still evolving," said lead author Dr. Matthias Ivy-Ochs. "The mountains are rising faster than they are eroding, and this trend is likely to continue in the future due to climate change."
