Dynamic Metasomatism: Stable Isotopes, Fluid Evolution, and Deformation of Albitite and Scapolite Metagabbro (Bamble Lithotectonic Domain, South Norway)

Figure 3

Field photos of albitites and dynamic albitisation. (a) Albitisation vein in metagabbro transforming the dark mafic rock to nearly pure albite. Locality Ringsjø. (b) Albitisation (red color) of tonalite (light color) along veining. Locality Fesettjern, Ringsjø area. (c) Vein albitisation (red color) causing chloritisation (greenish color) of scapolite metagabbro (dark grey). Locality Ringsjø. (d) Carbonate-rich albitite forming an approximate 5-metre wide vein deposit in the metagabbro. Locality Langøy. (e) Breccia containing clasts of albitised metagabbro in the matrix of a carbonate-rich albitite deposit. Field of view is approximately four metres wide. Locality Langøy. (f) Albitisation of metagabbro along veining with transformation to foliated albitic felsites. Locality Langøy. (g) Foliated albititic felsites with alternating light carbonate-albite and green-grey chlorite-schist bands. Locality Langøy. (h) Banded clinopyroxene-bearing albitite. Locality Åtangen.
