opaque minerals and other mineral constituents. Specimens from high-strain areas exhibit a fabric expressed as preferential alignment of biotite and/or chlorite. Other rock units found interspersed in footwall rocks include alkali feldspar granite porphyry (locally termed black porphyry) and Sudbury breccia. The black porphyry has a matrix composed of biotite and chlorite and has quartzo-feldspathic porphyroclasts. This unit is locally strained; metre-wide strain localizations are expressed as elongated porphyroclasts in the vertical plane. Figure 2.4A: Vertical cross-section of Creighton Mine showing geometry of footwall and hangingwall rocks as well as orebodies. Approximate section line is shown in Figure 2.2. Level numbers correspond to depth in feet; depth in metres is shown at the far right. Study area is shown between two dashed lines. Plum Orebody is referred to 6100 in this diagram. No vertical exaggeration. Figure modified from Vale Inco composite section, Creighton Mine. 12
