Upper Volcanic Section   d34S -1.8             Mean calculated based on work of Alt et al. (1989; 1995) and Alt & Anderson (1991). Comprises 300 m of 27% red halo and 73% dark gray basalts. Alt 1995
Upper Dike Section   d34S 0.6             Mean calculated based on work of Alt et al. (1989; 1995) and Alt & Anderson (1991). Comprises 300 m of 83% dark gray and 17% light gray basalts. Trace of pyrite veins. Alt 1995
ODP/DSDP Site 504B   d34S 3             Mean calculated based on work of Alt et al. (1989; 1995) and Alt & Anderson (1991). Comprises 300 m of 10.0% mineralized basalt, 89.9% transition zone basalts and 0.1% pyrite veins. Alt 1995
Mature Oceanic Crust   d34S 0.9             Mean calculated based on work of Alt et al. (1989; 1995) and Alt & Anderson (1991). Excludes unusually high-S and high-Fe gabbros. Total average of the altered oceanic crust (AOC) as weighted by the height (i.e. mass) of the upper and lower volcanic sections, upper and lower dikes, transition zone and plutonic gabbro section. d34S[AOC] = S (m[i]/m[total]) x d34S[i]. Alt 1995
Lower Volcanic Section   d34S -1.9             Mean calculated based on work of Alt et al. (1989; 1995) and Alt & Anderson (1991). Comprises 300 m of 99.9% dark gray basalts and 0.1% pyrite veins. Alt 1995
Lower Dike Section   d34S 2             Mean calculated based on work of Alt et al. (1989; 1995) and Alt & Anderson (1991). Comprises 300 m of 90% dark gray and 10% light gray basalts. Trace of pyrite veins. Alt 1995
Gabbro   d34S 0.4             Mean calculated based on work of Alt et al. (1989; 1995) and Alt & Anderson (1991). Excludes unusually high-S and high-Fe gabbros. Alt 1995
Gabbro 16 S 230   190       ppm Mean calculated based on work of Alt et al. (1989; 1995) and Alt & Anderson (1991). Excludes unusually high-S and high-Fe gabbros. Alt 1995
Altered Gabbro   d34S 0.1             Mean calculated based on work of Alt et al. (1989; 1995) and Alt & Anderson (1991). Excludes unusually high-S and high-Fe gabbros. Alt 1995
Altered Gabbro 16 S 620   180       ppm Mean calculated based on work of Alt et al. (1989; 1995) and Alt & Anderson (1991). Excludes unusually high-S and high-Fe gabbros. Alt 1995
