    Abstract

    Techniques of experimental design, based on generalized sampling models, are extremely important for “sampling a mountain,” especially because of the possible wide variability in element composition in the samples taken from that “mountain.” Current investigations are determining better guidelines in sampling and analytical procedures for minor-element studies in geochemical research. Too often, expensive analytical effort may be wasted owing to lack of proper design in the laboratory by the analyst and in geologic sampling by the geologist. Experimental design techniques are being applied to a wide variety of geologic sampling problems. Analytical procedures, including spectrochemical methods, are expected to change in accordance with the nature of the problem and the geologic sample. An example of sampling for minor-element analysis is given to illustrate types of geologic variance as compared to laboratory variance.
