Bermuda’s pink sand beaches hide a massive secret deep beneath the earth
Bermuda, famous for its pink sand beaches and blue waters, has become the center of a major scientific discovery. Scientists now believe the island was not formed in the normal way volcanic islands are created. This new finding may change what experts know about the Earth’s interior.
Earlier, researchers believed Bermuda was formed by a mantle hotspot, similar to the volcanic process that created Hawaii. However, recent chemical studies of Bermuda’s rocks showed unusual elements that do not match normal oceanic islands reportedly. Scientists found large amounts of water and heavy lead isotopes inside the volcanic rocks.
These materials may have come from the Earth’s mantle transition zone, a deep layer located around 250 to 400 miles below the surface. The area separates the upper and lower mantle and may store ancient recycled materials from Earth’s past.
A study titled ‘Sampling the volatile-rich transition zone beneath Bermuda’, explained that Bermuda’s volcanic rocks were formed nearly 30 million years ago when pressure pushed hidden materials upward through volcanic activity.
Scientists also think some of these materials may be pieces of ancient oceanic crust buried during the time of supercontinent Pangea (that existed approximately 335 to 175 million years ago, joining almost all of Earth's continents into one massive landmass).
This proves the Earth’s interior is not a simple, uniform layer. Instead, it contains different chemical regions and hidden reservoirs. By studying these rocks Bermuda’s rocks act like a natural record of Earth’s deep interior. The discovery has also raised new questions about the structure of the planet.
The island sits on an oceanic swell, where the ocean crust is higher than its surroundings. But there is no evidence of any ongoing volcanic activity creating that swell, the island's last known volcanic eruption was 31 million years ago. There may be several hidden chemical zones deep underground that have remained unchanged for millions of years.
