Carbonate mounds are an important feature along the European North-Atlantic margins. The presence of giant carbonate mounds in the Porcupine Seabight, on the Porcupine Bank, in the Rockall Trough and on the Rockall Bank, west of Ireland, have been known since the nineties and have been the target of several cruises during the last decade. However, the processes of mound build-up and mound nucleation are not yet completely understood.
Nature and Significance of the Recent Carbonate Mound Record focuses on the nature and significance of the carbonate mound record, and the nature and internal structure of the Challenger Mound is described in detail and compared with other mounds from the Irish margin and also with those from the Moroccan margin. The variety of mound characteristics are discussed, along with the associated oceanographic and geological settings and an appropriate classification for recent carbonate mound systems and cold-water coral reefs is presented.
