Micron-scale compositional changes across an Fe-rich compositional boundary layer (CBL). A micron-scale compositional transect obtained using EMPA through Si-rich glass adjacent to an Fe-rich CBL. Sample from the crust of the Kīlauea Iki lava lake (quench temperature of 1112 °C), sampled by the 1976 drill core at 45.5 m. Note the two different scales depending on element
