Article Synopsis
- Large igneous provinces (LIPs) are characterized by rapid magma production and environmental impacts, often leading to continental break-up and mass extinctions.
- The Siberian Traps, a major LIP, coincided with a mass extinction but lacked expected geological signs of uplift or lithospheric stretching associated with plume dynamics.
- New research indicates that recycled oceanic crust in the plume may be responsible for significant gas emissions, potentially triggering mass extinctions without prior uplift, aligning with existing stratigraphic evidence.
Plate tectonic processes introduce basaltic crust (as eclogite) into the peridotitic mantle. The proportions of these two sources in mantle melts are poorly understood. Silica-rich melts formed from eclogite react with peridotite, converting it to olivine-free pyroxenite.
