Geologists Reveal Earlier Collision of Americas, Redefining Geological History
Recent research published in Earth and Planetary Physics has uncovered evidence that the collision between Central and South America occurred millions of years earlier than previously believed. This discovery was made through the analysis of magnetic signatures in volcanic rocks from Colombia, which act as time capsules preserving the conditions of their formation. The study challenges the traditional timeline, suggesting that significant tectonic activity began during the Oligocene-middle Miocene period, rather than in the later stages as previously thought. This earlier collision led to the formation of a land bridge, which significantly impacted ocean currents and global ecosystems by allowing species migration between continents.
