A preliminary note on the geology of the area between Altevatn and Målselv, Indre Troms, N. Norway.

Abstract

An area of approx. 1,600 square kilometres in Indre Troms, N. Norway, has been geologically mapped. The area is built up of 1)granites and migmatites of the basement, overlain by 2)non-metamorphic sediments of the Hyolithus zone, on which, in overthrust position, rest 3)metamorphic Caledonian rocks. The overthrust Caledonain rocks have been divided into three \"sequences\", which may represent different thrust sheets. The most common rocks and structures found in the three sequences are given in table I, and illustrated in the profiles of figures 2 and 3. Fig 1 shows a sketch map of the area.
