Coupled Isotopes Reveal Sedimentary Sources of Rare Metal Granites

by Paul Asimow 17 June 202516 June 2025

Using coupled isotopes, a new study shows that a class of economically important granites are derived by sediment melting without mantle input.

Modeling Mantle Dynamics as the Earth Slowly Cools

by Paul Asimow 19 February 202511 February 2025

An update of the convection code ASPECT enables full coupling of plume dynamics with buoyancy effects of transition zone phase relations, showing how early layering gave way to whole-mantle plumes.

Machine Learning for Geochemists Who Don’t Want to Code 

by Paul Asimow 9 February 20249 February 2024

Geochemistry π is an easy-to-use step-by-step interface to carry out common machine learning tasks on geochemical data, including regression, clustering, classification, and dimension-reduction.

Machine Learning Identifies Source Volcanoes of Ash Deposits

by Paul Asimow 8 November 20236 November 2023

Tracing ash layers from explosive eruptions back to their source volcanoes is needed to evaluate hazards to population and aviation, a problem addressed by a new machine learning classification method.

Piecing Together the Roots of the Ancient Australian Continent

by Paul Asimow 25 October 202326 October 2023

Mineral compositions from numerous volcanic rocks that sample the mantle keel beneath Western Australia’s Kimberley Craton reveal the temperature and mineralogy that explain its long-lived stability.

Machine Learning Looks Anew at Isotope Ratios in Oceanic Basalts

by Paul Asimow 25 October 202224 October 2022

While past attempts to define isotopic endmembers and assign them a geodynamic significance ended in controversy, a machine-learning clustering algorithm offers a solution to this classical problem.

Why Do Arc Volcanoes Deform Less Than Ocean Island Volcanoes?

by Paul Asimow 15 August 202215 November 2022

Volcanic ground deformation is not simply correlated with erupted volume. Researchers propose that high concentrations of magmatic volatiles make systems more compressible and suppress deformation.

A New, Fast Computational Tool for Magmatic Phase Equilibria

by Paul Asimow 11 August 202222 December 2022

Thermodynamic calculations in multiphase, multicomponent magmatic systems can be slow and buggy. A new parallel architecture solves the free energy minimization problem much faster than alternatives.
