Atlas of the Underworld

Atlas of the Underworld

This intriguing title is actually a very serious cataloguing of subducted plates in the Earth's mantle. You can find it HERE. They identify 94 (!) different subducted plates. And that is only those from the last 300 million years! (After about 250 million years the subducted slab has come to the same temperature as the mantle and therefore cannot be distinguished by seismic tomography.)

There is a vast amount of data on the site and it is well worth looking at.
