Conclusions
The SCO is a complete ophiolite sequence that was disaggregated due to syn- and post-emplacement faulting. The absence of well-developed, layered gabbro, the presence of pyroxenite dikes such as Trinity ophiolite, the presence of small pockets of sepentenized dunites, the absence of well-developed dike complexes, the absence of chromite pods, well-developed and extensive point source volcanism onto pillow lavas, and the presence of gabbro pegmatoidic dikes in layered and isotropic gabbro (such as Trinity ophiolite) suggest that the SCO was formed in a slow-spreading center. The SCO is also classified as a LOT.
The available field and geochemical data show that the SCO was initially generated in a subduction-related marginal basin (or in a supra-subduction zone). A portion of the marginal basin was onramped above a subducting slab.
