Geological maps of the Coleman Mine (A) and Creighton Mine (B) areas, highlighting the relationship between the footwall lithologies and SIC melt sheet. Discontinuous zones of Sudbury Breccia are ubiquitous throughout the footwall and are not shown. The outlines of the Cu-Ni-PGE ore zones have been projected to the surface. At Creighton, the distal sample sites Old Creighton Town and South Pump Lake are also shown (modified after Ames et al. 2008). Ore bodies are outlined in red and projected to surface. Faults are depicted by dashed black lines.

Location Sudbury is located in east-central Ontario, approximately 250 mi (400 km) north of Toronto. The 11 stops illustrating the Sudbury Structure are located, for the most part, on or near Ontario 144 northwest of the city of Sudbury and within the city (Fig. 1). Stops 1 and 2 are on the north side of the Coleman Mine Road, a private road east of the town of Levack, and are located 1.6 mi (2.6 km) and 2.6 mi (4.2 km), respectively, east of the gateat the Levack Mine. Permission to enter must be obtained inadvance from the Mines Exploration Department, Into Ltd., Copper Cliff, Ontario P0M lN0. Stop 3 is on the west side of Ontario 144, 0.9 mi (1.4 km) north of its intersection with Regional Road 8, on the northwest corner of the Highway's intersectionwith a secondary road. Stop 4 is on the south side of Regional road 8, 0.1 mi (160 m) east of its intersection with Ontario 144. Stop 5 is on the west side of Ontario 144, 2.2 mi (4,5 km) south of the intersection of Ontario 144 and Regional Road 8, while Stop 6 is at a small roadside picnic area 3.1 mi (6.0 km) south of the intersection. Stop 7 is on the north side of Ontario 144, 3.7 mi (5.9 km) east of the Vermilion River crossing,1.2 mi (2.0 km) west of the Whitson River crossing. Stop 8 is

Plane-polarized thin-section images demonstrating the variation in mineral species. From the Coleman Mine, (A) chlorite replacing biotite, with later, dark red-brown biotite overprinting. This is accompanied by (B) titanite exsolution lamellae in chlorite and (C) an XPL image of a radial, Ni-bearing species of chlorite amongst sulfides. At the Creighton Mine (D) fibrous actinolite in distal breccia matrix is replaced by (E) prismatic zoned and (F) anhedral, blue-green, pleochroic varieties closer to sulfide zones. Compare this to the amphibole clusters at Coleman Mine (G) that replaced earlier pyroxene.

Backscattered SEM images of two forms of titanite observed at each mine locality. At the Coleman Mine, titanite is present as a reaction rim on ilmenite-magnetite grains (left), whereas at the Creighton Mine the titanite is primarily an anhedral, subtly zoned overprint on pre-existing biotite (right). Abbreviations: titanite – Tttn; ilmenite – Ilm; magnetite – Mag; allanite – All; chalcopyrite – Cpy.

A cross-section through a footwall ore system (in this case, based upon the McCreedy 153 East ore body at the Coleman Mine). The cross-section demonstrates the variation from contact-hosted ore zones, through to the type-2 and LSHPM styles found deeper in the footwall system (modified after Lightfoot 2015). At the Creighton Mine there is a similar transition from contact to footwall-hosted ore systems, although there is no type-2 mineralization documented at the mine and the ore zones are crosscut by several faults.

(A) A typical Sudbury breccia outcrop from close to the Creighton Mine exhibiting a dark grey, very fine-grained matrix hosting rounded clasts of locally derived host lithologies. (B) A sharp-walled sulfide vein from the Fraser Mine (adjacent to the Coleman Mine) in the North Range. The vein transitions from type-1 (chalcopyrite-dominant) to type-2 (bornite-dominant). The thin, dark grey-green alteration selvage can be seen adjacent to the vein. The host lithology is felsic gneiss with Sudbury Breccia (yellow arrow). Photo (B) courtesy of Dave Richardson.

Biotite from Coleman (open circles) and Creighton (filled circles) Mines with proximity to ore from distal to mineralized samples (blue-green-yellow-red). (A) Mg/Fe in chlorite and biotite, displaying the inherited geochemistry of replacement chlorite compared with coexisting biotite. (B) Tl/Rb versus Ni/Cr in biotite shows a relative increase in Tl content in mineralized samples, although the signature is reduced at the Creighton Mine. (C) Ni–Cu–Cr ternary plot demonstrating increased Ni/Cr towards ore, whereas Cu results are more scattered. (D) Whole-rock geochemical data for the Creighton Mine demonstrating the decreasing Rb values with proximity to mineralization that may reflect increasing Tl substitution in biotite over K, Rb, and Ce.
