Internal Ligurides

Figure 3 Location of the main ophiolitic belts and ophiolite complexes mentioned in the text (after Coleman, 1977 Ishiwatari, 1994 Moores et al., 2000). (1) Circum-Pacific Phanerozoic Multiple Ophiolite Belt (450-0 Ma) KM— Klamath Mountains (Trinity and Josephine, western USA) NC—New Caledonia PNG—Papua-New Guinea IB— Indonesian Back-Arc ophiolites. (2) Himalaya-Alps-Caribbean Mesozoic Belt (150-80 Ma) YZ—ophiolites of the Yarlung Zangbo Suture Zone, China OM—Oman (=Semail ophiolite). Sultanate of Oman and Unites Arab Emirates TR—Troodos, Cyprus VO—Vourinos and Pindos, Greece WA—Western Alps (Internal Ligurides and Lanzo) CU—Cuba ophiolites. (3) Appalachian-Caledonian Belt (450 Ma) BOI—Bay of Islands, Newfoundland.

Figure 13 Chondrite-normalized abundances of REEs in representative ophiolitic peridotites from the Internal Ligurides, New Caledonia, Oman, and Cuba (whole-rock analyses). Data from Rampone et al. (1996), Prinzhofer and Allegre (1985), Godard et al. (2000) (reproduced by permission of Elsevier from Earth Planet. Sci. Lett. 2000, 180, 133-148), and Proenza et al. (1999), respectively. Normalizing values after Sun and McDonough (1989).
