Early Pleistocene Volcanism in the Emile Baudot Seamount, Balearic Promontory (Western Mediterranean Sea). Marine Geology, Vol 207/1-4, 247- 257.

The recovery of calcareous breccia and other carbonate-cemented rocks from Mont dels Oliva in the Balearic Promontory indicates that both this seamount and the adjacent Mont Ausias Marc, east of Ibiza and Formentera islands, are of continental origin. Recent multibeam echosounder mapping and high-re...
