Bergh & Andresen (1987) have suggested correlation of the Senja Nappe (Troms District, North Norway)
with Ordovician-Silurian sequences of the Balsfjord Group which unconformably overlie mafic-ultramafic
rocks of the Lyngen Nappe. This is inconsistent with c. 475-500Ma post-metamorphic 40Ar/39Ar
hornblende cooling ages previously reported for the Senja Nappe. Field and geochronologic characteristics
indicate correlation of the Senja Nappe with other units of the regional Middle Allochthon Scandinavian
succession.
