    Iron ores of the Kiruna type are unusual formations restricted both in time and space. They are principally found in the Precambrian of Sweden and Missouri. The purpose of the present paper is to summarize the features that characterize the ores and to discuss their origin. It is concluded that the ores are intrusive-magmatic. The exhalative-sedimentary hypothesis is rejected. The following
