That is likely but quartz diorite is the identified animal that is the contact rock for many a nickel mine. By no means all of them, but it does turn up. It could be thought of as a porphyry of sorts. What is funny is the degree of silica in mines rocks in the Sudbury camp which was a source of much speculation. Strangely enough the rock that was the indicator for the Flin Flon camp was a quartz hornblende diorite or as the Hud Bay geos used to say, the QHD. A diorite could be an extremely altered gabbro. Wuite a few gabbros are altered to diorite on the surface.
