Two subvertical gabbroic dikes with widths of similar to 350 m (East-Muren) and >= 500 m (West-Muren) crosscut continental flood basalts in the Antarctic extension of the similar to 180 Ma Karoo large igneous province (LIP) in Vestfjella, western Dronning Maud Land. The dikes exhibit unusual geoc...
