cycle. The vast array of ore deposit types and their particular elemental compositions result from the complex interplay of favourable combinations of source, transport and depositional variables. Although ore formation is a common and intrinsic part of crustal evolution, large and super large ore deposits require the coincidence of particularly

The combination of known ore deposits and reflection seismic data has also led Sudbury to be chosen as the first test site for the use of 3D reflection seismic survey methods for detecting massive sulphide deposits in crystalline rocks.
World Class Ore Deposits, Reflections of the Earth’s Evolution
World class ore deposits can be defined commercially as deposits which contain metal concentrations in the upper quartile of resources size and/or grade, world wide, from which economic extraction can be undertaken, over a production period exceeding ten years, at a cost below the weighted average cost of cumulative production of the contained principal commodity.
