Notes: * ICP data were acquired in a shore-based laboratory at the Centre de Recherches Pétrographiques et Géochimiques-Centre National de la Recherche Scientifique (CRPG-CNRS), Nancy, France (major elements by ICP-AES, trace elements by ICP-MS; errors are <4% on all elements). — = undetermined. ICP-AES = inductively coupled plasma-atomic emission spectroscopy; MS = mass spectrometry. LOI = loss on ignition. This table is also available in ASCII format.
