Abstract
A new method is described whereby different types of stratigraphic and lithofacies maps can be integrated into a single coherent map. The end product contains an accumulation of features identified in the individual base maps, thereby simplifying the interpretation and recognition of trends. Depending on the number of maps employed, a specific standard value is allotted to each original map and its data are normalized so that every map has the same range of values. The new values for each data point are then added to give compound dimensionless values, which are contoured to produce a composite facies map. The method is illustrated by means of an example from a uranium-bearing braided river deposit in the Beaufort Group. Four conventional map types are combined in order to reconstruct the palaeo-environment. -from Authors
