[HTML][HTML] Atlas of the underworld: Slab remnants in the mantle, their sinking history, and a new outlook on lower mantle viscosity

DG Van der Meer, DJJ Van Hinsbergen, W Spakman - Tectonophysics, 2018 - Elsevier

Accretionary orogens through Earth history

PA Cawood, A Kröner, WJ Collins… - Geological Society …, 2009 - lyellcollection.org

Forearc ages reveal extensive short-lived and rapid seafloor spreading following subduction initiation

MK Reagan, DE Heaton, MD Schmitz, JA Pearce… - Earth and Planetary …, 2019 - Elsevier
Abstract The Izu–Bonin–Mariana (IBM) forearc contains a record of a widespread and short-
