Figure F11. REE data for Leg 201 and the volcanic zones of the Andes. The southern volcanic zone (SVZ) was compiled from Gutierrez et al. (2005) and D'Orazio et al. (2003), the northern volcanic zone (NVZ) is from Droux and Delaloye (1996), and the central volcanic zone (CVZ) is compiled from Petrinovic et al. (2005), Matteini et al. (2002), Richards and Villeneuve (2001), Siebel et al. (2001), Vatin-Perignon et al. (1996), and Dostal et al. (1977). Red, blue, and black lines are rare earth element (REE) plots for Leg 201 ash layers (black = Site 1227, red = Site 1228, blue = Site 1229).
