Aluminum silicates in the Prince Olav and Soya Coasts, East Antarctica

Description
Summary:This paper presents the regional distribution and textural features of aluminum silicates (kyanite, sillimanite, and andalusite) in the Prince Olav and Soya Coasts, East Antarctica. The data make it clear that the regional metamorphism in the region, probably Late Proterozoic in age, was of the medium-pressure type and that the regional metamorphic rocks locally underwent the retrograde alteration, including local development of andalusite, during the Early Paleozoic thermal event contemporaneous with the emplacement of granite and pegmatite.
