Figure F25. Downhole whole-rock cryptic chemical variation of Mg#, Fe2O3, TiO2, Cecn, and Zr. Pink line represents the minimum Ce measurement in Atlantis II basalts for reference. Note trace element spikes are not restricted to region of oxide gabbros but can also affect oxide-free gabbroic rocks. This typically indicates the rock has been affected by the addition of more fractionated melt (see text).
