A small deposit of mineralized coalified material in the upper Mississippian Ardness formation is exposed on the northwest shore of Cape George, Nova Scotia. The principal sulfides are pyrite and chalcocite accompanied by lesser amounts of bornite and other basemetal sulfides. Textural relations indicate that the ore minerals have intricately replaced the cell structure of organic matter occurring in a permeable horizon.It is suggested that the sulfides were introduced into a reducing environment created by decaying organic material, and were deposited either by adsorption, or by chemical reaction.
