| Abstract: | This paper deals withR-mode cluster analysis for more than 6000 analytical data from the samples of tectonite and mineralized rocks using the method
of multivariate statistical analysis on the basis of division of the tectonic fault systems in the Malage Ore Field andR-mode factor analysis for the analytical data from tectonite samples collected along various directions of the faults according
to fourteen variables related to the mineralizing elements which are selected in terms ofR-mode cluster analysis from the chemical composition of tectonites. Thus the distribution characteristics of primary halo
anomalies have been revealed with respect to the metallogenetic elements Sn, Cu, and Pb, Zn. The tecto-geochemical features
are shown by the primary halo anomalies, thus providing the theoretical basis for metallogenetic forecast in the ore field. |
