Abstract

A method is developed for expressing a dependent variable that is subject to systematic regional variations (trend) in terms of a set of independent geological variables. Trend surfaces are fitted to the independent variables, and the dependent variable is regressed on both the fitted trend values and the original observations for the independent variables. The method is applied to evaluate the areal distribution of gold occurrences in the Greenbelt of western Quebec as a function of a set of lithological variables.
