At first glance it seems reasonable in all respects (similar geochemistry, structure, and magnetostratigraphy) to attempt detailed correlations between the stratigraphies in holes only 1.2 km apart. However, one-to-one matches in geochemical trends and cyclic cryptic chemical and lithologic trends are unlikely between these two holes, given that each section has been affected by crystal-plastic deformation and shear zones and that individual small-scale layer-by-layer lateral continuity in ophiolites is demonstrated to be lacking, although larger lithologic units several hundreds of meters thick can be traced laterally for hundreds of meters (e.g., Casey and Karson, 1981; Casey et al., 1981). This is unlike some layered continental intrusions where single layers can be traced for kilometers or more. Many would also argue that slow-spreading magma chamber dimensions are small, so attempts to correlate are not warranted. Rather, it is probably better to think of the oxide-rich zones in terms of process and as a facies within the magma chamber complex where likely a strong chilled margin along the chamber wall allowed magma characteristics of the interior of the chamber (more primitive magmas) to become intimately intermixed with highly fractionated ferrobasalts formed at the external side of a boundary layer and where boundary layer liquids may be mobile. The boundary layer may be affected by repeated injections, eruption events, and internal small-scale convection and may itself erode and rebuild from time to time. Boundary layer fractionation may help to explain why oxide gabbros seemingly form at elevated Mg#s in the magma chamber complex and may be similar to other intrusions where "apparent" early oxide precipitation has been documented. Thus, we suggest that the processes in both holes may be the same, and, in fact, if the oxide-rich units are regarded as facies within the chamber complex, the broadly defined oxide units may correlate and continue laterally across the 1.2 km between them. This may also provide some constraint on chamber size, but there is no constraint available to suggest that zones crystallized simultaneously, and this seems unlikely. A series of short holes between the two sites may verify continuity, especially considering the many structural complications and shear zones that cut the sections.
