Pyroclastic density currents from large explosive eruptions can generate expansive ignimbrite deposits with planar, low-angle surfaces. We demonstrate the utility of these surfaces for constraining pr...

A vast sheet of volcanic rock in the Andes has preserved clues to a buried landscape that existed 22 million years ago, according to a new study led by UCL (University College London) researchers.

Crustal exhumation is central to mountain building, weathering, and sediment production processes, which significantly influence the composition and b…
