F. Demirmen 1973 A simple, semiobjective method is described to reduce the number of groups in a classification to an arbitrary level without losing contact with the geologic information contained in the evolving groups. The method, operated in a stepwise or cyclic manner, employs some of the commonly used numerical techniques, but avoids strict adherence to them to obtain geologically more meaningful results. The method is illustrated in a facies study of the upper Paleozoic rocks of southeastern Utah. ?? 1973 Plenum Publishing Corporation. application/pdf 10.1007/BF02111815 en Kluwer Academic Publishers-Plenum Publishers A semiobjective method for condensing classifications article
