Chemical and mineral compositions of basalts and volcanic glasses from DSDP Sites 65-483 and 65-485, supplement to: Kudo, A M; Barker, S E; Keil, K; Beeson, Marvin H (1982): Geochemical modelling of basalts from DSDP Leg 65, East Pacific Rise, Gulf of California.

Major and rare earth element (REE) data for basalts from Holes 483, 483B, and 485A of DSDP Leg 65, East Pacific Rise, mouth of the Gulf of California, support a simple fractional crystallization model for the genesis of rocks from this suite. The petrography and mineral chemistry (presented in detail elsewhere) provide no evidence for magma mixing, but rather a simple multistage cooling process. Based on its lowest TiO2 content (0.88%), FeO*/MgO ratio (0.95 with...
