Linking phosphogenic episodes on the southeast U.S. margin to marine δ13C and δ18O records: Correction
Geology, v. 25, p. 103–106 (February 1997)
Phosphorite ages shown in Figure 1 that were calculated using the Oslick et al. (1994) regressions were miscalibrated to a standard (NIST-987) 87 Sr/86 Sr value of 0.710235. The appropriate standard value is 0.710255. Recalibration of the phosphorite Sr-ratios makes the ages agree better when calculated by both methods (Oslick et al., 1994; Hodell et al., 1991). See Figure 1 below.
