· Metal signatures that define individual ore deposits and ore deposit classes overlap to create the continuum shown in Fig. 8. The main trends of Zn to Cu-Au, Cu-Au to Au only and Ni to Sn-W define the gross architecture of MH-Space ( Fig. 8 ) with more subtle variations in inter-element ratios defining intra-class and intra-deposit divisions.

Often ore deposits are classified after examples of their type, for instance Broken Hill type lead-zinc-silver deposits or Carlin–type gold deposits. Genesis of common ores [ edit ] As they require the conjunction of specific environmental conditions to form, particular mineral deposit types tend to occupy specific geodynamic niches, [6] therefore, this page has
