Mature Oceanic Crust 5 B 0.026             Boron compositions as found in altered oceanic crust.  Smith et al. 1995
Mature Oceanic Crust 5 B 5.2           ppm Boron compositions as found in altered oceanic crust.  Smith et al. 1995
Mature Oceanic Crust 5 d11B 3.7             Boron compositions as found in altered oceanic crust and averaged from all localites by which samples were taken (DSDP Holes, ODP Holes, Troodos and Oman ophiolites)..  Smith et al. 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
