	Geology of the Mauken tectonic window, Målselv, Troms

Abstract:

This report presents the results from bedrock mapping in the Mauken tectonic window, carried out in several periods in 2011-2013. During the NGU MINN program, the Mauken area has been subject to a high-resolution airborne geophysical survey (magnetometry, radiometry, EM), followed by bedrock mapping and structural geology investigations. The work in the Mauken area is part of a larger project in southern Troms, with the goal to work out a structural-tectonic-metallogenic model and interpretaion for the basement areas in the whole region.

	Geologic and structural studies around two geophysical anomalies in Troms, Northern Norway.

;Norges geologiske undersøkelse;TIDSSKRIFTARTIKKEL;NGU; No.247;57-77 pages

Abstract:

The geology and structures of two windows (the Mauken and the Divielva windows, see fig. 1) are outlined. For the Precambrian supracrustal rocks of the Mauken window, two formations names and one group name are suggested. Hyolithus zone sediments in autochthonous position along the southern margin of the Mauken window show that the Caledonian thrusting exeeded 70 km. In both window structures "ReliefÏberschiebung" took place. A magnetic anomaly in the Mauken window is explained by local concentrations of normally accessoric magnetite in an antiformal hinge zone in sericite-chlorite schists. The relations between an E-W directed magnetic anomaly and the structures of the Divielva window are discussed.
