    As they require the conjunction of specific environmental conditions to form, particular mineral deposit types tend to occupy specific geodynamic niches, therefore, this page has been organised by metal commodity. It is also possible to organise theories the other way, namely according to geological criteria of formation. Often ores of the same metal can be formed by multiple processes, and this is described here under each metal or metal complex.

  • Mineral Ore Deposits: Meaning, Origin and Types Geology

    An ore deposit may be either of igneous or of sedimentary origin. Some deposits are related to metamorphic processes and are as such classified as deposits of metamorphic origin. An ore deposit may be either of igneous or of sedimentary origin. Some deposits are related to metamorphic processes and are as such classified as deposits of metamorphic origin. Within these three broad modes of origin, a mineral deposit of economic value might have originated due to set of simple or complex processes. Types of Ore Deposits: 1.
