    The Jijal ultramafic–mafic complex in Pakistan probably preserves the most complete fragments of the petrological Moho. However a few studies argue for multiple origins (including petrogenetic speculations and tectonic reconstructions) for different lithologies. One of the main reasons for this dispute is the lack of direct age information of the ultramafic rocks.

  • Structural features of ophiolitic chromitites in the

    The chromitite-bearing peridotites of the Zambales mafic-ultramafic complex form the lowermost level of the Zambales ophiolite which exposes a complete ophiolitic sequence. The chromitites occur close to the peridotite/gabbro transition zone. The chromite orebodies are structurally classified into three major types (1) concordant tabular deposits (2) strings of pods and (3) pocketlike deposits.
