| Abstract |
Projections in the pseudo-quaternary system diopside-plagioclase-olivine-quartz (di-pl-ol-Q) are used in this paper as a base on which to plot additional compositional, petrologic or tectonic variables. Used in this manner, the projections provide a sensitive means of displaying and evaluating the chemical variability of mid-ocean ridge basalt (MORB) suites, such as that of the Galapagos 95.5° W propagating rift system, and allow mantle controls on the chemical variability of MORB to be distinguished from the predominant effects of shallow-level crystal fractionation and mixing. |
