Sudbury deposits are sea-bed volcanigenic type deposits that form in association with felsic pyroclastic rocks. Sudbury is the greatest concentration of felsic pyroclastic volcanism in the world. Within 1500 feet of every mine in Sudbury there is a rhyolite flow and felsic bomb area. The Norite in Sudbury, both felsic and mafic is a flow rock that deposited itself placidly on the fractured secondary sublayer which is a sediment. Yes, there are plentiful mafic flows in the Lac Rocher area. You may call them intrusives. But it is a volcanic-sedimentary area, like Sudbury and Timmins. The nickel deposits in the Lac Rocher area, past and present are found at the contact of these flows in a broad northeast closing antiform. EC<:-}
