AB - The quartzofeldspathic charnockitic orthogneisses in the coastal regions of the Bamble sector are highly fractionated in K, Rb and other LIL elements. This fractionation is related to the imposition of the granulite-facies assemblages, and thus to the single high-grade metamorphic event that can be recognized in these rocks. Rb/Sr isotopic studies restrict this event to the pre-Grenvillian; it occurred some 1540 m.y. ago, the age confirmed by newly presented data. In this area the Sveconorwegian cycle (1200-900 m.y.) is represented only by intrusive event(s). Associated low-T hydrous fluids were introduced, causing low-grade mineralogical alterations in the pre-existing gneisses and which disturbed, and sometimes reset, the Rb/Sr isotopic systems. There was no regional Grenvillian high-grade reworking in the sector.-J.M.H.
