In the Coastal Complex two petrographically distinct types of periodotites are identified, one probably representing differentiates of MORBs, the other having relatively high CaO/Al2O3 and low TiO2/Na2O. The restricted occurance of the latter indicates that their formation was confined to a fracture zone region. They are assocated with cumulates, ultramafics and harzburgite tectonics and may have been incorporated into rising serpentinite diapirs.-AuthorsWoods Hole Oceanog Inst, Woods Hole, MA 02543, USA.
