Carbonate Rocks: Cleaning with Suspensions of Hydrogen-Ion Exchange Resin

The surface of carbonate rocks may be cleaned by etching or polishing or both, with hydrogen-ion exchange resin. This treatment reveals details in texture and fossil morphology so clearly that thin sections may be often dispensed with. Of four cleaning methods, (i) allowing resin to settle around the sample, (ii) stirring with a magnetic stirrer, (iii) agitating with an ultrasonic generator, and (iv) directing a jet stream at the sample, the first method was best for large specimens and the second method was best for well cuttings and chips.
