The geology of a mafic dyke at Roerkulten, Sverdrupfjella, western Dronning Maud Land, Antarctica

The mafic dyke is metamorphosed to amphibolite-facies and is calc-alkaline with intermediate SiO 2 (∼56%) and high Al 2O 3 and TiO 2 and is transitional between basaltic to andesitic compositions. The dyke has high Sr, Zr and Ba contents. The steep chon
