Description/Abstract This paper describes a method of impregnating increments of 3-in. diameter cores of unconsolidated sediment with a polyester resin so that they can be studied in the same way as ordinary rock samples.^ The impregnation of soft sediments has 3 main advantages: (1) the slabbed cores show many structures and textures that are invisible or indistinct in broken or sliced soft-sediment cores; (2) multiple slabs of the same core permit a serial, 3-dimensional examination of sedimentary structures, particularly those produced by organisms; (3) impregnation and slabbing simplify storage, provide specimens for sectioning, and make the cores readily available for study.^ Briefly, the method consists of vacuum and pressure impregnation of the dried cores with polyester resin.^ The resin jells and cures overnight, and the cores can be slabbed with a conventional diamond slabbing saw.
