Bulletin of the Geological Society of Greece, 34(4) ABSTRACTThe anisotropy of magnetic susceptibility is a physical property of the rocks widely used in petrofabric stud ies and other applications. It is based on the measurement of low-field magnetic susceptibility in different direc tions along the sample. From this process several scalar properties arise, defining the magnitude and symmetry of the AMS ellipsoid, along with the magnetic foliation and lineation, namely the magnetic fabric. A case study is presented, dealing with the deformation of the Mont-Louis-Andorra pluton. Finally, the method was applied in Tertiary magmatic rocks from the Rhodope Massif, revealing their magnetic character and internal struc tures.

Quaternary geology, geomorphology and tectonics in the Ogosta river valley system, the Danubian plain (Bulgaria)

“…By applying the method of anisotropy of magnetic susceptibility (AMS) on rock samples several parameters -scalar and directional-arise (Zananiri, 2001 and references therein). The AMS measurements were performed using the KLY-2 Kappabridge (Geofysica, Brno) equipment at the University Paul-Sabatier, of Toulouse (France).…”

Lamprophyric rock locations in Greece

“…(Melidonis 1980;Pantziris 2000) N 37.628971, E 25.194155 A few lamprophyre dikes and sills intrude the periphery of the N-NW Tinos granitoid. (Kolokotroni 1992;Christofides et al 1998;2007;Soldatos et al1998;Perugini et al 2004;Zananiri 2004;Pipera 2015) N 41.200331, E 23.566788 In the area of the Vameno stream, between the villages of Orini and Xerotopos, three lamprophyre dikes cut the southern margins of the deformed Vrondou granitoid. They run sub-parallel to the margin.…”
