How new subduction zones form is an emerging field of scientific research with important
implications for our understanding of lithospheric strength, the driving force of plate …

Subduction zones are pivotal for the recycling of Earth's outer layer into its interior. However,
the conditions under which new subduction zones initiate are enigmatic. Here, we …

Subduction zones are unique to Earth and fundamental in its evolution, yet we still know little
about the causes and mechanisms of their initiation. Numerical models show that far-field …

Boninites are rare, high-Si, high-Mg, low-Ti lavas that have considerable tectonic
significance, especially for recognizing and interpreting episodes of subduction initiation in …

Abstract The Izu–Bonin–Mariana (IBM) forearc contains a record of a widespread and short-
lived subduction initiation event in the early Eocene. We present new high-precision ages to …

Abstract The Izu‐Bonin‐Mariana (IBM) fore arc preserves igneous rock assemblages that
formed during subduction initiation circa 52 Ma. International Ocean Discovery Program …

Documenting the early tectonic and magmatic evolution of the Izu–Bonin–Mariana (IBM) arc
system in the Western Pacific is critical for understanding the process and cause of …

Tectonic discrimination diagrams are a key tool for understanding ancient volcanic rock
origins. In this contribution we compile over 15,000 whole rock compositions to re-evaluate …

Determining whether plate tectonics or some other mode of planetary dynamics operated in
the early Archean is one of the most contentious and debated areas of Earth Sciences today …

Subduction initiation is one of the least understood aspects of plate tectonics. In an effort to
obtain the first in situ magmatic record of subduction initiation, the International Ocean …
