En petrografisk och mineralogisk studie av en komplex gång bestående av metadiabas och kvartskeratofyr i Kiirunavaaragruvan
Summary: The purpose of this paper is to give a petrographic and mineralogic description of a dyke complex, consisting of a metadiabase and a quartz keratophyre. The type locality is the northern part of the Kiirunavaara apatite-rich iron ore, situated in northern Sweden. In this part of the mine, the dyke complex has caused problems with rock stabil ity and water inflow. The dyke is well mapped f
