IV. METHODS OF SAMPLE PREPARATION AND X

SAMPLE PREPARATION The method of sample preparation is nondestructive (except for grinding) and the sediment fractions can be recovered for further testing or refinement. An exception to this is that calcite, aragonite and, to some extent, dolomite, gypsum, and anhydrite are dissolved in the decalcification process.
