For decades, the mantle was thought to be fairly homogenous, or well-mixed. Most geology students are taught that the mantle...is stirred thoroughly by convection currents. But since the 1990s, images of the mantle began to show strange slabs of rock deep in the mantle that appear to be very cold compared to the temperature of the surrounding rock.

[T]he presence of the cold slabs ... have created the most consternation among conventional Earth scientists. These sunken slabs are thought to be subducted ocean seafloor that made it all the way through the mantle and are essentially resting on the top of the core. They are only about 60 miles thick. At today’s rates of a few inches or less per year, it would take about 70–100 million years for a slab to reach the base of the mantle. How can these slabs still be so cold when the surrounding mantle is so hot ...?

Cold slabs of rock deep in the mantle may be a dilemma for conventional Earth scientists, but not for Flood geologists.
...in the catastrophic plate tectonics model, such a temperature difference is to be expected if the slab rapidly subducted into the mantle just a few thousand years ago.
