Along subduction zone megathrust faults, the transition from smectite to illite with depth
occurs at temperatures of∼ 150° C and has long been hypothesized to be one of the …

An update of the geothermal gradient and heat flow maps for offshore Malaysia based on oil
and gas industry data is long overdue. In this article we present an update based on …

Active and widespread CH4 accumulations and emissions in the Nankai Trough subduction
zone are attested by numerous mud volcanoes, gas plumes, and gas hydrates containing …

1. Abstract International Ocean Discovery Program Expedition 385 drilled organic-rich
sediments and intruded sills in the off-axis region and axial graben of the northern spreading …

Naturally occurring microbially induced smectite-to-illite (Sm-I) reaction is of great interest to
understand the control for the conventional Sm-I transformation, the source of bioavailable …

Earthquakes are expected to nucleate within velocity‐weakening materials; however, at the
updip limit of the subduction seismogenic zone, the principal lithologies exhibit velocity …

Compositional changes, dehydration reactions and fluid flow in subducted sediments
influence seismogenesis and arc magmatism in subduction zones. To identify fluid flow and …

Abstract The Integrated Ocean Drilling Program, as part of the Nankai Trough Seismogenic
Zone Experiment, recovered samples of mud and mudstone from the Kumano forearc basin …

Circulation of water at moderate depths in subduction zones is dominantly driven by clay
mineral dehydration over distinct pressure and temperature gradients. The signature of …

One of the more prominent architectural elements of the Nankai subduction margin, offshore
southwest Japan, is an out‐of‐sequence thrust fault (megasplay) that separates the inner …
