| contents | Mineral and whole-rock geochemical data are presented for chilled dike margins from the lower sheeted dike complex of Deep Sea Drilling Project/Ocean Drilling Program (DSDP/ODP) Hole 504B. Compositions of phenocrystic plagioclase (An80-89); olivine (Fo82-86); clinopyroxene (Wo52En40Fs8, with Cr2O3 up to 1.2%); and rare chromian spinel (Cr# 43) are consistent with those from the lavas and the upper dike complex recovered previously (DSDP Legs 69, 70, 83, and ODP Leg 111). Major and trace element compositions fall in group D of Autio and Rhodes (1983) and have high CaO/Na2O, and low TiO2, K2O, and (La/Sm)N values consistent with previous analyses from this site. |
