Book excerpt: Excerpt from Igneous Rocks and Iron Ores of Kiirunavaara, Luossavaara and Tuolluvaara The region examined by the writer comprises the two ore mountains Kii runavaara and Luossavaara and the continuation towards the sides and north ward of the igneous rocks forming their slopes, further on, the ore mountain Tuolluvaara and some exposures located chie y north of the latter and con sisting of rocks more or less closely related to the ore-bearing ones. The object of the work was to make an exhaustive analysis of the petrographic characters of the igneous rocks and ores in question, and to explain the mutual relations of the different rock varieties as well as their relations to the ores. In this way one might expect to get a better insight into the mode of origin of the iron ores of the region. The ore problem is naturally the most interesting one in this region, but there are also, in the writer's field of work, as well as in the neighbouring regions, other phenomena of great interest.
