A recent study reveals a massive, lighter rock slab beneath Bermuda, nearly 13 miles thick, which lifts the island above the oceanic crust. This discovery challenges previous understanding of Bermuda's volcanic origins, suggesting the island sits on a buoyant, ancient intrusion rather than a recent volcanic hotspot, and highlights the island's unique geological history.
Scientists have discovered the remains of an island the size of Iceland off the coast of Brazil, submerged beneath the waves. The island, which existed around 45 million years ago, was found through the presence of red clay and distinctive mineral makeup, indicating its tropical origins. The discovery sheds light on the geological history of the area and has potential economic value due to its ferromanganese crusts. Brazil is seeking to extend its maritime borders to include the Rio Grande Rise, where the island was found, and prove its geological similarities to the nation.
