In minor road-cuts occurs two layers of semi-massive magnetite, 1.2 and 2 m thick. The lower, magnetite-amphibole-pyroxene banded IF (Samples JSFE15.04-05) contains minor sulphides and overlies calcareous mica schist, and calcite marble is situated above. The thickness of the marble is hard to decide due to lack of exposure and granitic intrusions. The upper, magnetite-amphibole-pyroxene-quartz banded IF (Sample JSFE15.06) is located 30 m further east, approximately 20m higher in the tectonostratigraphy
