Web site: Figure F2. Summary diagram of rift events in the Newfoundland-Iberia rift. Leg 210 drilling was at the boundary between the central and northern rift segments (Black triangle at top of the figure). Hiatuses probably developed because of tectonic uplift associated with rifting. "E" at the bottom indicates evaporites deposited in shallow rift basins during the Late Triassic to Early Jurassic. Minor magmatism in the rift is documented south of Tagus Abyssal Plain in Gorringe Bank (Schärer et al., 2000) and on Galicia Bank (Schärer et al., 1995; Beard et al., 2002). The Southeast Newfoundland Ridge at the southern margin of the Newfoundland Basin was a major locus of volcanism in the Barremian–Aptian (Tucholke and Ludwig, 1982). Open arrows = earliest proposed seafloor spreading, solid arrows = estimates for latest initiation of spreading. (Southern segment earliest = 145–131 Ma [Anomaly M20–M11] [Srivastava et al., 2000; Mauffret et al., 1989]; central segment earliest = 140 Ma [Anomaly M17] [Srivastava et al., 2000], latest = 127–125 Ma [Anomaly M5–M3] [Whitmarsh and Miles, 1995; Russell and Whitmarsh, 2003]; northern segment = ~122 Ma [Anomaly M0] [Srivastava et al., 2000; Boillot, Winterer, Meyer, et al., 1987]).
