Generalized geology of the Reed Lake – Snow Lake area modified from Syme et al. (1995) and Bailes et al. (1994). The Morton Lake fault zone (MLFZ) is interpreted to represent the basal thrust (Syme et al. 1995; Lucas et al. 1996) that separates the Snow Lake area from the central Flin Flon Belt (i.e., Amisk collage). The Snow Lake area is characterized by a structural style and by lithologies that are more comparable to the Kisseynew domain than those observed in the central Flin Flon Belt. The Snow Lake area consist of a series of Kisseynew-type allochthons of volcanic and sedimentary rocks.

Simplified geology of the central and eastern portions of the Flin Flon domain showing major tectonostratigraphic assemblages and plutons, and locations of mined VMS deposits. F = Flin Flon, S = Snow Lake. The Snow Lake area is characterized by a structural style and rock types that are more comparable to the Kisseynew domain than those in the Amisk Collage of the central Flin Flon belt. The Snow Lake area consists of a series of Kisseynew-type allochthons of 1.89 Ga volcanic and 1.85 to 1.83 Ga sedimentary rocks soled by the Morton Lake fault zone (MF; Syme et al., 1995). The red rectangle shows the area depicted in Figure 4a and b.

Schematic cross section showing a series of allocthons in the Reed Lake – Snow Lake area (bottom left to upper right in Fig. 2). The 1.89 Ga panels of volcanic rocks are seperated by thrust faults and panels of 1.84 Ga Burntwood Group sedimentary rocks. The allocthons of volcanic and younger sedimentary rocks are cut by late successor arc 1.84–1.83 Ga granite plutons. VMS mines are restricted to arc assemblages, with seven of the 10 mines in the Snow Lake area located in an allocthon composed of Snow Lake arc assemblage rocks.

A. Plan view of the 1.89 Ga Anderson sequence, Chisel sequence, and Snow Creek sequence components of the Snow Lake arc assemblage. Arrows show facing direction of supracrustal rocks. Also shown are ca. 1.84 to 1.83 Ga successor arc sedimentary and intrusive rocks, ca. 1.84 Ga thrust faults (red, teeth), and ca. 1.78 Ga normal faults (solid black lines). Colored circles and ellipses show distribution of VMS deposits (red are Cu rich, magenta are Zn rich): A = Anderson Lake, B = Bomber, C = Chisel Lake, CK = Cook Lake, CN = Chisel North, G = Ghost Lake, Jn = Joannie zone, L = Lost Lake, La = Lalor Lake, Li = Linda, M = Morgan Lake, P = Photo Lake, Pn = Pen zone, Pt = Pot Lake, R = Rod, Ra = Ram zone, Rd = Raindrop, S = Stall Lake. The barren sulfide “horizon” (locally known as the Foot-Mud horizon) is a sulfide-bearing, fine-grained, volcaniclastic unit located at the contact between the Anderson (primitive arc) and Chisel (mature arc) sequences. B. Simplified geologic map of the Snow Lake area. Letters indicate informal names of units (identified in legend). The designation “p-arc” after the unit name in the legend indicates that it belongs to the primitive arc (Anderson sequence) and “m-arc” indicates that it is part of the mature arc (Chisel sequence). VMS deposit names and designations are the same as those given in the caption for A.
