Structural position of ore-bearing areas in Finland

By A.K. Mikkola and H. Niini

Abstract

The Finnish ore deposits of the economically most important metals — mainly Cu, Fe, Ni, Pb, Ti and Zn — are grouped according to their metal content. This grouping closely follows the genetic classification of the ore deposits. A really the ore deposits in Finland are concentrated into four elongated zones, each of which probably contains several metallogenic provinces. The location of the zones shows a close relationship to structural features, especially fault zones and to the location of basic intrusive rocks. There seems to be a negative correlation between the zones and the areas of granitic rocks. This is explained as meaning that the concentration of the ore material has followed deap-seated and extensive fault zones
