Notes: Standards: MAR = mid-Atlantic Ridge, a Lamont-Doherty Earth Observatory (LDEO) laboratory standard of normal mid-ocean-ridge basalt; K1919 = an LDEO standard equivalent to BHVO-1 generally used as a drift-correcting standard; BAS140 = an ODP internal standard equivalent of a Leg 140, Hole 504B, diabase (Dick, Erzinger, Stokking, et al., 1992; Sparks and Zuleger, 1995). References: 1 = Govindaraju (1994); 2 = LDEO; 3 = Plumlee (1998a, 1998b) - preliminary values; 4 = ODP (1999 shipboard compilation). This table is also available in ASCII format.
