    The Paleomagnetism of the Otish Gabbro from North of the Grenville Front, Quebec
    Canadian Science Publishing ; 1973

    Abstract: The Otish Gabbro, which intrudes the Otish Mountains Group, is normally magnetized and has a paleomagnetic pole at 107 °W, 35 °N, α 95  = 9°. The Otish Mountains Group has been correlated with the Mistassini Group and/or the Huronian Supergroup. The pole for the Otish Gabbro lies between that of the 2175 m.y. old Nipissing diabase, which is intrusive into Huronian strata, and the pole for the 1700 m.y. old Sudbury norite. If the Otish Mountains Group is correlative with the 2300 m.y. Huronian, the Otish Gabbro was intruded a considerable time after the deposition of the sedimentary strata.

    The transition from dyke to sill in the Otish Mountains, Quebec; relations to host-rock characteristics
    Canadian Science Publishing ; 1987

    In: Canadian Journal of Earth Sciences, Canadian Science Publishing, Vol. 24, No. 1 ( 1987-01-01), p. 110-116
    Abstract: The Otish gabbro sills intrude Aphebian clastic rocks lying uncanformably on the Archean rocks of the Superior Province close to its juncture with the Grenville Province. The sills are undated but by inference may be ca. 1750 Ma. Two dyke swarms are known in the vicinity, the 1950 Ma, northwest-trending Mistassini dykes and a northeast-trending swarm of unknown age extending 600 km from Senneterre to the Otish Mountains and possibly another 300 km to the northeast. The trends of feeder dykes to the Otish sills are physically compatible with the dominant northeast dykes, which are therefore considered to be the feeders and should be called the Otish dykes.The Otish sills appear to be a unique occurrence along the 900 km dyke trend, possibly, but not entirely because of the chances of preservation. The general form of the Otish sill complex is a triangle bounded on the north by the east–west lip of the sedimentary basin, on the southwest by a northwest-trending Otish feeder dyke, and on the southeast by the underlying northeast feeder dykes. These dykes segment the sills into a series of four or five separate intrusive complexes, small in the northwest and becoming larger to the southeast. The regular inclination of tension fractures in the basal chilled margin of the sills suggests a crude pattern of flow from the feeder dykes inward to the centre of the sheets.Interpretation of the sedimentary sequence indicates that the Otish clastics were deposited higher on the paleoslope than the Mistassini carbonates. Although few dykes intrude the deeper basin, the magma rose and formed sills within the higher sequence. This variation may be explained by the different mechanical character of the two types of cover rock controlling the dyke behaviour. The relatively plasto-viscous Mistassini carbonate–shale sequence resisted the formation of tension fractures, whereas the brittle elastics opened easily, allowing the magma to rise into the stratified sequence, forming the sill complexes.

    The tectonic significance of some basic dyke swarms in the Canadian Superior Province with special reference to the geochemistry and paleomagnetism of the Mistassini swarm, Quebec, Canada
    Canadian Science Publishing ; 1986

    Abstract: The Mistassini dykes extend northwest from the Mistassini embayment and comprise both tholeiitic and komatiitic suites. They are probably 〉  2000 Ma old and yield two major paleomagnetic components. One of these, with a pole at 131°W, 13°S, is thought to be an overprint related to the Elsonian Disturbance 1400–1500 Ma ago. A very steeply down (and reversed) component may be primary and has a pole at 080°W, 50°N.These spacial, chemical, and age relationships between the Mistassini, Molson, Marathon, and Payne River dyke swarms and the Aphebian supracrustal fold belts on the perimeter of the Superior Province suggest a genetic relationship between the dyke swarms and the fold belts. The supracrustal belts are evidence of the opening and closing of oceans, and the dyke swarms are evidence of early-stage failed arms related to these openings. More rarely (for example, the Payne River dykes), early-stage dyke swarms are developed and preserved parallel to the edges of newly developed spreading plate boundaries. Presumably if a spreading episode stops, the dykes themselves may remain as the only evidence of that event. Probably all the world's great continental dyke swarms have the above-described tectonic setting, and the number and extent of dyke swarms during a geological epoch may be a measure of the number and vigour of spreading events.

    Tectonic evolution of the Northern Volcanic Zone, Abitibi belt, Quebec
    Canadian Science Publishing ; 1992

    Abstract: The Archean Abitibi Subprovince has been divided formally into a Northern Volcanic Zone (NVZ), including the entire northern part of the subprovince, and a Southern Volcanic Zone (SVZ) on the basis of distinct volcano-sedimentary successions, related plutonic suites, and precise U–Pb age determinations. The NVZ has been further formally subdivided into (i) a Monocyclic Volcanic Segment (MVS) composed of an extensive subaqueous basalt plain with scattered felsic volcanic complexes (2730–2725 Ma), interstratified with or overlain by linear volcaniclastic sedimentary basins; and (ii) a Polycyclic Volcanic Segment (PVS) comprising a second mafic–felsic volcanic cycle (2722–2711 Ma) and a sedimentary assemblage with local shoshonitic volcanic rocks.A sequence of deformational events (D 1 –D 6 ) over a period of 25 Ma in the NVZ is consistent with a major compressional event. North–south shortening was first accommodated by near-vertical east-trending folds and, with continued deformation, was concentrated along major east-trending fault zones and contact-strain aureoles around synvolcanic intrusions, both with a downdip movement. Subsequent dextral strike-slip movement occurred on southeast-trending faults and major east-trending faults which controlled the emplacement of syntectonic plutons (2703–2690 Ma).This study suggests that the NVZ, which is a coherent geotectonic unit, initially formed as a diffuse volcanic arc, represented by the MVZ, in which the northern part, represented by the PVS, evolved into a mature arc as documented by a second volcanic and sedimentary cycle associated with major plutonic accretion. Volcano-sedimentary evolution and associated plutonism, as well as structural evolution, are best explained by a plate-tectonic model involving oblique convergence.

    A new astrobleme: Ile Rouleau structure, Lake Mistassini, Quebec
    Canadian Science Publishing ; 1976

    Abstract: Ile Rouleau (50° 41′ N, 73 °53′ W) in Lake Mistassini has a circular shape, 1 km in diameter, with a glacial tail pointing southwest. The island is formed of argillaceous and micritic dolomite of the Mistassini Group and shows extensive tectonic disturbances, in contrast to the very slight regional deformation. The distortion of the bedding appears to reflect both solid rotation and internal deformation of tectonic blocks. Dikes and irregular masses of polymictic breccia with a matrix of finely comminuted rock particles cut the beds. Shatter cones are conspicuous all around the island. A few silty quartz grains in some breccia fragments show multiple sets of planar features. The size of the shatter cones is limited by the thickness of the beds in which they occur. Their average apical angle is 94°, and the bedding to cone axis angle appears to be between 45°and 70°. The cones point upward and towards the center of the island. These features suggest that the Ile Rouleau structure is an astrobleme (scar left by the impact of a large cosmic body). The age of the structure is unknown within wide limits; the Mistassini group in which it occurs is upper Aphebian (1.8 b.y.) and it is covered by Pleistocene Glacial deposits. The small size and good preservation suggest that the structure is fairly recent.
