Basanite appears early in the [[alkaline magma series]] and basanites are found wherever alkaline magma is erupted.<ref>{{cite book |last1=Philpotts |first1=Anthony R. |last2=Ague |first2=Jay J. |title=Principles of igneous and metamorphic petrology |date=2009 |publisher=Cambridge University Press |location=Cambridge, UK |isbn=9780521880060 |edition=2nd |pages=139–148}}</ref> This includes both continental and ocean island settings.

During eruption of the [[Laacher See]] [[caldera]] some 12,900 years ago, the final phase of the eruption, which tapped the deepest part of the [[magma chamber]], produced basanite [[lapilli]] mixed with [[phonolite]] lapilli.<ref>{{cite book |last1=Schmincke |first1=Hans-Ulrich |title=Volcanism |date=2003 |publisher=Springer |location=Berlin |isbn=9783540436508 |page=33}}</ref> This has been interpreted as fresh magma injected into the magma chamber that may have helped trigger the eruption.{{sfn|Schmincke|2003|p=205}}
