A procedure for impregnating rocks in preparation for sectioning is described. Good results are obtained without the need for evacuation. The resin is a polyester type with low viscosity and good wetting power. The procedure has been used successfully on loess, sand, silt, clay, and well-cemented rocks containing softer materials subject to plucking.
