Classifications vary, and in general they depend on one or more of the following criteria: •Descriptive •Morphology •Commodity •Genetic •Environment12.3: Ore Genesis - Geosciences LibreTextsOften ore deposits are classified after examples of their type, for instance Broken Hill type lead-zinc-silver deposits or Carlin–type gold deposits. Classification of hydrothermal ore deposits is also achieved by classifying according to the temperature of formation, which roughly also correlates with particular mineralising fluids, mineral associations and structural styles.
