Abstract

Phlogopites in forsterite-bearing marbles of the metasedimentary Faurefjell formation in the high-grade Precambrian rocks of Rogaland, SW Norway, contain <=24.6 wt.% BaO and <=13.9 wt.% TiO (sub 2) . The very high TiO (sub 2) content and the low cation sums could be taken to indicate incorporation of tetrahedral Ti and/or Ti-vacancy substitutions. However, combinations of Ti-oxy and Ti-vacancy substitution schemes explain the analytical data better.
