Cryo-BIB-SEM of oil-brine filled Lixhe limestone

Cryo-BIB-SEM image of oil-brine filled Lixhe limestone. Oven dried limestone (grey) was saturated with oil (red) and sodium-chlorine brine (blue). The fluid-filled sample was slush-frozen in LN2 and a 2mm² large cross-section was prepared using Broad-Ion-Beam-milling under cryogenic conditions. Subsequently the sample was analyzed in a cryo-SEM using secondary electrons, backscattered electrons, and chemical analysis using EDS.
