Introduction of Oceanic Mid-plate Superstructures (OMS) in volcanic studies
New research introduces the concept of Oceanic Mid-plate Superstructures (OMS) to describe large volcanic structures formed from various volcanic sources over time. The study focuses on the Melanesian Border Plateau (MBP), an example of an OMS, revealing its formation through four distinct volcanic episodes, combining hotspot activity and lithospheric movements, contributing to around 222 000 km² of intraplate volcanism.
