Sultan's Combinaton proved to be the most useful of the spectral band ratios.  The ophiloite proper manifests as pink in the false color images.  The primary composition of the ophiolite is peridiotite, represented by the bright pink areas, whereas the gabbroic base of the ophiolite can be identified by it's slightly darker appearence. In addition to the ophiolite proper, the deep-ocean pelagic sediments (dominated by carbonate) can be seen as lineated green regions to the south of the ophiolites.  These carbonates are stratagraphically above the ophiolite and represent sedimentation that occurred near the mid-ocean spreading center.  Other carbonates, dominated by dolomite, manifest as bright yellow.  These rocks make a relatively young sedimentary package not related to the ophiolite emplacement.  The young carbonates have experienced only minor deformation associated with regional doming.
