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.

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.

Correlations Between Subduction of Linear Oceanic Features and Arc Volcanism Volume Around the Pacific Basin [PDF]
Geochemistry, Geophysics, Geosystems, 2022, 23 (12),
pp.e2022GC010553, 2023 Arc volcanoes, created by magma generated from the dehydration of subducting slabs, show great variability in their sizes and along-arc spatial distributions. In this study, we address a fundamental question, namely, how do subduction zones and volcanic arcs respond to the subduction of ``atypical'' oceanic lithosphere.

Elastic anisotropy of lizardite at subduction zone conditions [PDF]
Geophysical Research Letters 49 (2022), 2022 Subduction zones transport water into Earth's deep interior through slab subduction. Serpentine minerals, the primary hydration product of ultramafic peridotite, are abundant in most subduction zones. Characterization of their high-temperature elasticity, particularly their anisotropy, will help us better estimate the extent of mantle serpentinization ...
