Beardmore orogeny (original) (raw)

The Beardmore orogeny was a mountain building event in the Neoproterozoic affecting what is now Antarctica. The event is preserved in the Trans-Antarctic Mountains, potentially in the Shackleton Range and by argillite-greywacke series in the Horlick Mountains, Queen Maud Land and the Thiel Mountains. Upright folds, asymmetric overturned or recumbent isoclinal folds first identified by Elliott in 1975 was interpreted in 1992 by Edmund Stump as indicative of compressive and convergent tectonic activity.
