B Laying down of the Onaping microbreccia as a fallout blanket or suevite. A pool of magma is also generated from the target rocks. C Ascent of the Sudbury Irruptive as an impact-triggered magma from the deep crust. The shock-generated melt rock is incorporated into the micropegmatite. The Irruptive differentiates with micropegmatite above and norite below. Apophyses of micropegmatite invade the overlying Onaping suevite. Emplacement of Irruptive is accompanied by foundering. D. The Whitewater sediments (Chelmsford Formation) are laid down as a greywacke deposit in the Sudbury Basin. Detailed sketch shows sulphide deposit emplaced as an impact splash in footwall along with breccia and noritic matrix. E. Geologic situation today after distortion by Grenville orogeny and erosional deleveling. 503.
