{{Short description|Geologic mechanism}} In geology, '''anorogenic magmatism''' is the formation, intrusion or eruption of magmas not directly connected with orogeny (mountain building).<ref name="Sheppard1986">{{cite book|chapter=Chapter 10 – Igneous Rocks III – Isotopic Case Studies of Magmatism in Africa, Eurasia and Oceanic Islands|last=Sheppard|first=S.M.F.|editor=Valley, J.W |editor2=Taylor, H.P. |editor3=O'Neil, J.R. |title=Stable Isoptopes in High Temperature Geological Processes (Reviews in Mineralogy – Volume 16)|date=1986|publisher=Mineralogical Society of America|isbn=0-939950-20-0|page=[https://archive.org/details/stableisotopesin0000unse/page/319 319]|chapter-url=https://archive.org/details/stableisotopesin0000unse/page/319}}</ref> Anorogenic magmatism occurs, for example, at mid-ocean ridges, hotspots and continental rifts. This contrasts with orogenic magmatism that occurs at convergent plate boundaries where continental collision, subduction and orogeny are common.<ref>[http://www.mv.helsinki.fi/home/jsheinon/amanda/indexeng.html Anorogenic magmatism in Dronning Maud Land (Antarctica)]</ref>
