If significant, an additional description of the mature of the fracture filling including ~oisture, colour, consistency or hardness, soil cr rock type ard origin is added. The sigmificance of each of these parameters with respect tO e~gineering behaviour is discussed and stanlard descriptive terms defined. Reccmmerdations are m~de for the hardli~6 and storage of rock cores. Some useful techniques for the logging of core are discussed.
