Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Evidence of low velocity layers at the top and bottom of the Mantle Transition Zone (MTZ) below the Uttarakhand Himalaya, India [PDF]
Scientific ReportsThe Mantle Transition Zone (MTZ) beneath the Uttarakhand Himalaya has been modelled using Common Conversion Point (CCP) stacking and depth-migration of radial P-receiver functions.

Upwellings and Mantle Ponding Zones in the Lower Mantle Transition Zone (660–1000 km)
GeosciencesConvective instabilities at various boundary layers in the earth’s mantle—including the core–mantle boundary, mantle transition zone and lithosphere-asthenosphere boundary— result in upwellings (mantle plumes) and downwellings (subducting slabs).

Surprises from the top of the mantle transition zone [PDF]
Geology Today, 2016 Recent studies of chromite deposits from the mantle section of ophiolites have revealed a most unusual collection of minerals present as inclusions within the chromite. The initial discoveries were of diamonds from the Luobosa ophiolite in Tibet. Further

Heterogeneous distribution of water in the mantle transition zone inferred from wavefield imaging
Earth and Planetary Science Letters, 2019 The amount of water in the Earth's deep mantle is critical for the evolution of the Earth. Mineral physics studies revealed that the mantle transition zone can store several times the volume of water in an ocean. However, the actual water distribution in

Slab pileup in the mantle transition zone and the 30 May 2015 Chichi‐jima earthquake
Geophysical Research Letters, 2016 The 30 May 2015 Chichi‐jima M8 earthquake is one of the largest deep focus earthquakes ever recorded and its depth of 682 km puts it near the base of the mantle transition zone.

Compositional heterogeneity in the mantle transition zone
Nature Reviews Earth & Environment, 2022 Earth’s mantle transition zone (MTZ) is characterized by several sharp increases in seismic wave speed between ~300 km and ~850 km depth. These seismic discontinuities are generally attributed to solid-state phase transitions that lead to density and viscosity increases, which could cause a barrier to convection by segregating thermally and chemically ...
