Summary

Abstract:
New outcrops of the Hope Bay Formation and Larsen Basin rocks have been exposed by the recent ice retreat on Tabarin Peninsula, Northern Antarctic Peninsula. Quartzose, very low-grade metasedimentary rocks, cropping out at Balegno Nunataks are assigned to the Permian-Triassic Hope Bay Formation, and dioritic rocks are asigned to the Antarctic Peninsula batholith. Sedimentary rocks exposed at Rebulis Nunatak closely resemble Lower Cretaceous sedimentary rocks cropping out at nearby Troilo Nunatak, western Tabarin Peninsula. These rocks are correlated with the lower Gustav Group (Barremian-Coniacian) of the Larsen Basin. This new record confirms that the Larsen Basin extends over southern Tabarin Peninsula magmatic arc. |
