Abstract:
Outcrops of hydro-volcanic deposits on Deception Island are stratigraphically re-classified. The sequence was assigned to a pre-caldera phase, but it has very different compositional and consolidation characteristics, enabling it to be differentiated and redefined as a new unit. In this paper, it is stratigraphically relocated as a historical eruption, on the basis of its compositional similarity to ash-falls in Bransfield Basin. The studied deposits are bimodal (basaltic/rhyolitic) implying a relationship with magma immiscibility. The occurrence of more acidic periods would allow relatively more explosive vents with greater particle dispersion to take place. © 2004 Asociación Geológica Argentina.
