Figure F18. Extended rare earth element (REE) spidergrams showing chondrite-normalized trace element abundances of gabbroic rocks from Subunit IIB. Samples in top plot are from the highest level of the unit, and the basal plot shows lower levels of the core. Normalization values after Anders and Grevesse (1989).
