Geology of the Ramírez Nunatak, Jason Peninsula, Antarctic Peninsula

The 118 m thick volcanic sequence exposed at the Ramírez Nunatak, western Jason Peninsula (65°57′S, 60°33′W), Antarctic Peninsula, is composed of a lower section where ash fall tuffs and volcanic sandstones are exposed, and an upper section dominated by rhyolithic ignimbrites. The volcaniclastic sed...
