Abstract [en]

Sparre is a previously mined apatite iron ore deposit, situated in Malmberget, in northern Sweden. It is currently owned by the Swedish company LKAB, but has not been mined since the middle of the 20th century. High degree of deformation and alteration in the area has resulted in many of the rock types in the area being hard to determine. This thesis aims to better characterize these rocks by core logging, microscopic analysis and geochemical investigations to aid future mapping and modeling of the lithologies in the area. The results show that there are five major rock types that vary a lot in appearance due to different types of alteration. The stratigraphy consists of volcanic rocks of intermediate to felsic composition, cut by three different types of intrusions; mafic intrusions of monzo-dioritic composition, Perthite-monzonite suite granitic rocks and Lina suite granitic rocks.
