Basic (komatiitic) pillowed and massive flows (Gale, 1973) form the base of the succession in the Rambler area, overlain by mafic pyroclastic and pillowed volcanic rocks. A center of silicic pyroclastic volcanism formed during the later stages of mafic volcanicity and the sulfide deposits in the area are related to exhalite activity during the waning stages of this silicic volcanicity. The mafic pyroclastic volcanism was followed by deposition of mafic volcanogenic sediment and/or waterlain tuff and by local extrusion of pillow lava units. The entire sequence is cut by numerous mafic dikes and sills.All the rocks in the area have suffered polyphase deformation and metamorphism in the upper greenschist facies. The first two deformations involved intense strain with 1 < k < infinity. Later deformations are less intense. Large-scale folds are tentatively recognized as the product of the second and third deformations. The shape and orientations of the sulfide bodies have been modified during deformation. The orebodies are elongate parallel to the F 2 and F 3 fold axes and to the maximum axis of the D 2 deformation ellipsoid.The Ming massive sulfide deposit is a stratabound Cu, Au, Ag producer and occurs at the top of the silicic volcanic pile. The Rambler deposit is similar to the Ming and both have been compared to the Archean and/or Kuroko types of deposits. The East deposit and the Big Rambler Pond deposit were Cu producers and have been compared to Cyprus-type deposits. It is concluded that the deposits in the Rambler area cannot be classified as a single type and that different types coexist in one environment.
