Kenneth Sims and other research scientists recently discovered that mafic volcanism of Henrys Fork Caldera -- located in ...

Yellowstone is most famous for huge explosive eruptions that create large calderas. Outside Yellowstone Caldera, however, ...

Two types of magma exist under the park. One is basaltic magma, which triggers most volcanic activity on Earth. It erupts ...

This type of magma is called “basaltic”, and it tends to produce pretty mild eruptions. Hawaii is also a basaltic hotspot, for instance. However, hotspots can also melt the material around ...

These deposits contained basaltic magma in their lower sections and rhyolitic magma in their upper sections. The team managed to estimate the quantities, discovering a storage of melt material of ...

So, rather than using absolute ages to constrain the timescales of individual eruption durations, my research uses the width of a thermal imprint created by a magmatic intrusion to quantify the ...

the generation and transport of basaltic magma; the development and evolution of volcanic systems; magma degassing; volcanic hazard assessment; radiometric methods for dating igneous and sedimentary ...

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.

Specialization in petrologic and structural evolution of Precambrian dike swarms; basaltic magma evolution, and quantitative modeling of magmatic differentiation.
