Dec 2016 – New paper in EPSL: Dating the formation of mantle heterogeneities

Diagram

Constraining the scale and the nature  of mantle heterogeneities is critical to understand mantle dynamics, but there is still limited information available on the mechanisms and timing of formation of mantle heterogeneities observed in exhumed mantle rocks. Most of those heterogeneities are layered pyroxene-rich veins that form as a result of melt focusing and subsequent…

July 2015 – Marienel is back!

Marienel

After a successful summer as a PEP student last year, Marienel Basiga (San Jose State University) is back into the experimental laboratory to figure out how slab melts modify the composition of mantle wedges in subduction environments. She is now a prestigious Summer Student Fellow at WHOI!

Oct 2014 – Meet Marienel Basiga

Marienel Basiga

Gaining research experience led Marienel Basiga, a junior geology major at San Jose State University, to the Woods Hole PEP. Her research project with mentor Veronique Le Roux at Woods Hole Oceanographic Institution, in a field of geology known as experimental petrology, involved measuring grain-scale permeabilities of calcite and quartz through high-pressure, high-temperature experiments to…

Oct 2014 – New paper: Tracking flux melting

Studying Nature

“Tracking flux melting and melt percolation in supra-subduction peridotites (Josephine Ophiolite, USA)” is now In Press for Contributions to Mineralogy and Petrology. Abstract Here, we investigate the scale and nature of melting and melt percolation processes recorded by 17 supra-subduction peridotites collected in a ~70 km2 area in the northern portion of the Josephine ophiolite (Western USA). We present…
