The discovery of an ancient slab of seafloor beneath the Pacific that has lingered for over 120 million years sheds light on geological processes deep within Earth.
Researchers uncovered a cold, dense rock slab that may explain a gap in a giant mantle blob, offering a rare glimpse into Earth's deep dynamics.
This study is significant as it presents a present-day example of cold downwellings disrupting the deep mantle blobs, a phenomenon not well understood previously.
The ancient slab's positioning beneath the Pacific Ocean reveals critical interactions between Earth's lithosphere and mantle, crucial for understanding our planet's geological history.
