“We can combine the microbiological findings with those from serpentinization, to understand the factors that control ...

The analysis of mantle-derived rocks on increasingly smaller scales and advances in geodynamic modelling are providing new insights into the nature of mantle heterogeneity and magmatic processes.

The upper mantle also wells up so that no gap opens between the tectonic plates. Our paper outlines the preliminary interpretations of this drill core. The rocks are mostly made up of a rock ...

G eoscientists have used earthquakes to study the composition of the lower portion of the Earth’s mantle under the Pacific ...

Scientists have long been puzzled by volcanoes that erupt far from the edges of tectonic plates—known as intraplate volcanoes ...

Continents are composed of relatively light blocks that float high on the mantle, like gigantic, slow-moving icebergs. Seafloor is made of a denser rock called basalt, which presses deeper into ...

Some of this volcanism occurs when water-rich mantle upwellings trigger the melting of mantle rocks, forming magma that can erupt. Helene Wang and colleagues used plate reconstructions from the past ...

The mantle is made up of different layers. The upper mantle is hard but below that is semi-molten rock called magma. Crust The crust is the outer layer of the Earth on which we live. It is the ...

This shallow flow aligns with geochemical evidence of plume-derived signatures in the basin’s northern volcanic zones. The study further identifies divergent mantle flow regimes: west-east ...
