The stratigraphy and tectonics of the Rautuvaara iron ore district, northern Finland
The sedimentary rocks of the Rautuvaara iron ore district constitute m epicontinental association that, from oldest to youngest, comprises quartzites, quartz-feldspar schists, carbonate and skarn rocks with their associated magnetite mineralisations and amphibolites They are overlain by Kumpu-format...
