PETROTYP has been designed for clustering igneous rock compositions given as concentrations of major element oxides. This program is based on principles of hierarchical grouping of objects that are characterized by an array of parameters described as an objective function (Ward, 1963). The major principle involves a subsequent combining of samples having the minimum geochemical distance (GD) with respect to other rocks or average cluster compositions formed at a previous stage. ...
