Atlas of the Underworld | van der Meer, D.G., van Hinsbergen, D.J.J., and Spakman, W., 2017, Atlas of the Underworld: slab remnants in the mantle, their sinking history, and a new outlook on lower mantle viscosity, Tectonophysics
Subduction leaves a distinct geological record at the Earth’s surface, in the form of major mountain ranges such as the Andes or the Himalaya, or major volcanic arcs such as the Pacific Ring of Fire. Using these geological records, Earth Scientists have developed ways to determine when and where subduction episodes started and ended. On this website, we provide the current state-of-the-art of the images of slabs in the Earth’s upper and lower mantle, and the geological interpretation of when and where they were subducting. In the main article associated with this website, we use the information provided here to deduct physical properties of the mantle and slabs, and discuss ways to develop reference frames for plate reconstructions of the geological past. On this website, we provide open access to all slabs, organized by location, age, depth, and name.
