Figure 2. a) Topographic map showing faults (black lines; Eguez et al., 2003), and purported sutures zones (white dashed lines; Alvarado et al., 2014). The Coastal Cordillera (CC), the Western Cordillera (WC) and the Eastern Cordillera (EC) are indicated on the map as well as the Montalvo fault (Mf) and the Ponce Enríquez fault (PEf). b) Existing, and new thermochronological data of the Ecuadorian Andes (non-reset AHe and AFT ages and volcanism ages indicated by black dots; Spikings et al., 2000, 2001, 2004, 2010; Winkler et al., 2005); intrusions (orange) and faults. c, d) Swath profiles across the Montalvo and the Ponce Enríquez reverse faults, respectively and thermochronological ages (Garanda and Cuenca profiles).
