Gold mineralization and metallogenesis associated with mantle dynamics in East China
East China can be divided into two parts: the North China Block (or North China Craton) (NCC) and the South China Block (SCB). The mechanism for the destruction of the NCC and the large-scale magmatic activity in the SCB during the Mesozoic is a major ...

Plume–ridge interactions: ridgeward versus plate-drag plume flow [PDF]
The analysis of mid-ocean ridges and hotspots that are sourced by deep-rooted mantle plumes allows us to get a glimpse of mantle structure and dynamics.

The flow of high‐temperature and compositionally enriched material between mantle plumes and nearby spreading centers influences up to 30% of the global mid‐ocean ridge system and represents a significant, but currently unconstrained, flux of volatiles ...

Explores the behavior of carbon in minerals, melts, and fluids under extreme conditions
Carbon trapped in diamonds and carbonate-bearing rocks in subduction zones are examples of the continuing exchange of substantial carbon ...

Discovering ancient mantle plumes is challenging. By combining electrical conductivity with mineral physics modelling, this work finds a remnant of an ancient plume trapped in the mantle transition zone and sheds new light on mantle plume physics.

Robust Seismic Images of the Hawaiian Plume
To image the Hawaiian plume and the plume‐lithosphere interaction, we determine a robust 3‐D shear‐wave velocity (Vs) model of the upper mantle and the mantle transition zone (MTZ) beneath Hawaii by jointly inverting teleseismic S‐wave arrival times ...

N–S rifting is one of the most typical tectonics in southern Tibet, but its formation mechanism remains controversial. Geophysical observations indicated spatial correlations between rifts and lithospheric mantle anomalies, presumably caused by ...

Volcanoes are usually found near the borders of tectonic plates that are violently either pushing or pulling at each other. Mysteriously, however, volcanoes sometimes erupt in the middle of these plates instead. The culprits behind these outbursts might be giant pillars of hot molten rock known as mantle plumes, jets of magma rising up from near the ...

Tracing the Iceland plume and North East Atlantic breakup in the lithosphere
Plumes are domains where hotter material rises through Earth´s mantle, heating also the moving lithospheric plates that may experience thinning or even continental breakup.

Recent studies indicate that mantle plumes, which transfer material and heat from the earth’s interior to its surface, represent multifaceted upwellings.
