The 2018 Outstanding Student Poster and PICO (OSPP) Award is awarded to Lisa de Ruiter for the poster/PICO entitled:

Quartz dissolution and M-S-H cement precipitation in a high pH ultramafic system (de Ruiter, L; Austrheim, H.; Gunnæs, A.; Dysthe, D. K.;)

Lisa de Ruiter is a PhD student at the Physics of Geological Processes group at the University of Oslo and works on rock cementation by magnesium silicate hydrate cement. The aim of her study is to obtain knowledge about magnesium silicate hydrate cement from nature that could be used in the development of environmentally friendly industrial cement. The cement forms when high pH, Mg-rich fluids that originate from the weathering of serpentinites react with quartz, which subsequently dissolves and is replaced by the cement. This unique phenomenon occurs in SE Norway and also provides new insights into weathering, fluid-rock interactions and interfacial dissolution-reprecipitation processes at surface conditions.
