Mar 24, 2020 (Sheree Hinz) - South Range contact deposits occur in depressions or embayments in the Footwall of the Sudbury Igneous Complex or as protrusions into the Footwall immediately adjacent to this contact. The hanging wall is almost invariably quartz-rich norite, while Footwall rocks consist of the metavolcanic and metasedimentary rocks of the Elsie Mountain and Stobie Formations, or the Creighton and Murray Plutons. All of the Footwall rocks have been brecciated to form Sudbury Breccia and have been metamorphosed to the greenschist and amphibolite facies.

Mar 24, 2020 (Sheree Hinz) - There is a crude zonation of ore types within the orebody with the more sulphide-rich zones located closest to the footwall, and weaker sulphide mineralization located toward the hanging wall. Massive sulphide and inclusion massive sulphide are usually located along the footwall contact, or as stringers penetrating the footwall.
