=== Metamorphic deposits ===
These are ore deposits which form as a direct result of metamorphism.
* [[Skarn]]s occur in numerous geologic settings worldwide.<ref name="Meinert-1992">{{Cite journal |last=Meinert |first=Lawrence D. |date=1992 |title=Skarns and Skarn Deposits |url=https://journals.lib.unb.ca/index.php/GC/article/view/3773 |journal=Geoscience Canada |language= |volume=19 |issue=4 |issn=1911-4850}}</ref> They are silicates derived from the recrystallization of carbonates like [[limestone]] through [[Contact metamorphic|contact]] or [[regional metamorphism]], or fluid related [[Metasomatism|metasomatic]] events.<ref name="Einaudi-1981">{{Cite book |last1=Einaudi |first1=M.

* [[Greisen]]s, like skarns, are a metamorphosed silicate, quartz-mica mineral deposit. Formed from a granitic [[protolith]] due to alteration by intruding magmas, they are large ore sources of [[tin]] and [[tungsten]] in the form of [[wolframite]], [[cassiterite]], [[stannite]] and [[scheelite]].<ref name="Pirajno-1992">{{Cite book |last=Pirajno |first=Franco |url=https://www.worldcat.org/oclc/851777050 |title=Hydrothermal Mineral Deposits : Principles and Fundamental Concepts for the Exploration Geologist |date=1992 |publisher=Springer Berlin Heidelberg |isbn=978-3-642-75671-9 |location=Berlin, Heidelberg |oclc=851777050}}</ref><ref>{{Cite book |last=Manutchehr-Danai |first=Mohsen |url=https://www.worldcat.org/oclc/646793373 |title=Dictionary of gems and gemology |date=2009 |publisher=Springer |others=Christian Witschel, Kerstin Kindler |isbn=9783540727958 |edition=3rd |location=Berlin |oclc=646793373}}</ref>
