Goldschmidt 2015

Dr. Dorfman presented a poster titled, “Electronic properties of iron in silicate glasses in the lower mantle” and chaired a session titled “Modeling the Mineralogy of the Deep Earth” at the 2015 Goldschmidt conference in Prague.

Microscopy: I found love

In love with a new image from yesterday’s work on the focused ion beam/scanning electron microscope! The sample center looks somewhat like a morel mushroom, with blobs of silicate in a network of iron-rich melt. A particularly cheerful blob can be found in the upper right corner of the region of interest.
