Research reveals the scale at which Earth’s mantle composition varies

By Science, , , , ,

A new study by geochemists from Brown University suggests that Earth’s mantle varies in composition over kilometer-sized pockets.

PROVIDENCE, R.I. [Brown University] — New research by Brown University geochemists provides new insights on the scale at which Earth’s mantle varies in chemical composition. The findings could help scientists better understand the mixing process of mantle convection, the slow churning that drives the movement of Earth’s tectonic plates. (more…)

New study reveals insights on plate tectonics, the forces behind earthquakes, volcanoes

By Science, , , , , , , , , , , , , , , , , , , , , , , , , , ,

The Earth’s outer layer is made up of a series of moving, interacting plates whose motion at the surface generates earthquakes, creates volcanoes and builds mountains. Geoscientists have long sought to understand the plates’ fundamental properties and the mechanisms that cause them to move and drift, and the questions have become the subjects of lively debate.

A study published online Feb. 27 by the journal Science is a significant step toward answering those questions. (more…)
