Structural development of the Naxos migmatite dome
Published:January 01, 2004
This paper presents new structural data on the Naxos migmatite dome, exhumed in the central part of the Aegean Sea in Greece. The dome is cored by anatectic granites and migmatites that have preserved magmatic textures, and it is mantled by a dominantly metasedimentary sequence grading outward from amphibolite to greenschist facies. The elliptical shape of the dome is outlined by a composite transposition foliation in the mantling metasedimentary sequence. The lineation trends NNE-SSW and is associated with top-to-the-NNE shearing. Within the first order dome, kilometer-scale second order domes are evidenced by the orientation of the magmatic fabric, of the...
