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

Figure 2

Field photos of scapolite metagabbro and dynamic scapolitisation. (a) Gabbro with scapolitisation front. Locality Langøy. (b) Scapolite metagabbro with veining filled by scapolite and amphibole. Field of view is approximately one metre wide. Locality Langøy. (c) Scapolite metagabbro with a high density of scapolite veining resulting in a layered structure in the rock [20]. Field of view is approximately one metre wide. Locality Langøy. (d) Scapolite metagabbro with amphibole veining and flattened foliation [20]. Locality Langøy. (e) Brecciated amphibolite with a thin scapolite vein filling and rounded clasts. Locality Åtangen. (f) Intensive scapolitisation of an evolved breccia with amphibole veins, amphibole + scapolite matrix, and rounded clasts. Locality Åtangen. (g) Brecciated amphibolite with scapolite veins undergoing flattening. Locality Åtangen. (h) Foliated scapolite-bearing amphibolites. Locality Åtangen.
