Control of Subduction Zone Age and Size on Flat Slab Subduction [PDF]
Frontiers in Earth Science, 2020 Flat slab subduction is an enigmatic style of subduction where the slab attains a horizontal orientation for up to several hundred kilometers below the base of the overriding plate.

Seamount Subduction and Earthquakes [PDF]
Oceanography, 2010 Seamounts are ubiquitous features of the seafloor that form part of the fabric of oceanic crust. When a seamount enters a subduction zone, it has a major affect on forearc morphology, the uplift history of the island arc, and the structure of the ...

Marine terraces of the last interglacial period along the Pacific coast of South America (1° N–40° S) [PDF]
Earth System Science Data, 2021 Tectonically active coasts are dynamic environments characterized by the presence of multiple marine terraces formed by the combined effects of wave erosion, tectonic uplift, and sea-level oscillations at glacial-cycle timescales.

Fast Holocene slip and localized strain along the Liquiñe-Ofqui strike-slip fault system, Chile
Scientific Reports, 2021 In active tectonic settings dominated by strike-slip kinematics, slip partitioning across subparallel faults is a common feature; therefore, assessing the degree of partitioning and strain localization is paramount for seismic hazard assessments.

Thermal evolution of Andean iron oxide–apatite (IOA) deposits as revealed by magnetite thermometry
Scientific Reports, 2021 Magnetite is the main constituent of iron oxide–apatite (IOA) deposits, which are a globally important source of Fe and other elements such as P and REE, critical for modern technologies.

Timescales of subduction initiation and evolution of subduction thermal regimes
Earth and Planetary Science Letters, 2022 Subduction zones are first-order features of plate tectonics on Earth, yet the mechanisms by which subduction initiates remain enigmatic and controversial. Here, we reappraise the timing of metamorphism of the rock units first detached from the leading edge of the downgoing slab during initiation of the Neotethys subduction, now preserved in the ...
