The Precambiran schists and gneisses of Lakselv valley, northern Norway.
The principal rocks of the Lakselv valley area are well-foliated hornblende schist and mica-quartz schists and lesser amounts of quartzite and marble. The hornblende schist overlies most of the mica-quartz schists and in several places is interlayered with them on a small scale. The structure of the...

The principal rocks of the Lakselv valley area are well-foliated hornblende schist and mica-quartz schists and lesser amounts of quartzite and marble. The hornblende schist overlies most of the mica-quartz schists and in several places is interlayered with them on a small scale. The structure of these layered rocks consists of several broad folds trending and plunging easterly. Most of these rocks probably represent sediments that were metamorphosed in Precambrian time under conditions of the epidote-amphibolite facies. Some of the hornblende schist has been transformed to small masses of hornblende gneiss and diorite, and a large sill of quartz diorite and a small stock of granite have been emplaced. These rocks, which were originally more or less massive, have been metamorphosed to gneisses; this metamorphism obscures their original mode of emplacement.
