FIG. 6. A. Interpreted fluid-flow pattern within the detachment zone. High fluid flow is restricted to intensely brecciated rocks leading to precipitation of vein-filling iron oxides. By contrast, the relatively homogeneous marble is pervasively impregnated by fine-grained goethite. See text for discussion. B. Schematic diagram (not to scale) showing detachment fault–related mineralization in the roof of the Phyllite-Quartzite unit in western Crete (for comparison, see Long, 1992, fig. 36).
