Abstract

A quick-setting epoxy mixture is available that enables relief-peels to be made in the field for revealing primary sedimentary structures in sandy sediments. The mixture consists of five parts each of CIBA Epoxy 6005 and CIBA Epoxy 6010, three parts of CIBA Hardener 850 and one part of CIBA Hardener 830. Polymerization generally occurswithin 1.5 hours and is not inhibited by either freshwater or saltwater. An additional four hours is required for curing. Depth of impregnation is controlled by sediment texture, sorting, and permeability. Moisture and low temperatures inhibit polymerization; the method is not recommended for temperatures below 45 degrees F.
