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.
