The 2017 Outstanding Student Poster and PICO (OSPP) Award is awarded to Robert Holder for the poster/PICO entitled:

Titanite petrochronology of ultrahigh-temperature (UHT) calc-silicates from southern Madagascar: laser-ablation split-stream ICP-MS spot analyses and depth profiles; EPMA trace-element maps (Holder, R. M.; Hacker B. R.)

Robert Holder is a PhD student at the University of California, Santa Barbara. In his research, he geochemistry and radiometric dating of metamorphic, igneous, and sedimentary rocks to understand the development of Earth’s orogenic systems such as modern Tibet, the Western Gneiss Region of Norway, the southern Madagascar, and the Bohemian Massif of central Europe.
On his poster, he presented U-Pb dates and trace-element data from granulite-facies titanite collected in southern Madagascar and explored the roles of diffusion and fluid-mediated recrystallization in resetting titantite U-Pb dates, Zr-in-titanite temperatures, and titanite composition in general.
