Plutonic igneous environments
Ekanite is very often metamict (Mindat).
At the Tombstone Mountains, Dawson mining district, Yukon, Canada, ekanite has been found in a glacial erratic syenitic boulder, associated with fluorite, garnet, quartz, microcline, clinopyroxene, apatite, sodic plagioclase, hematite, thorogummite, zircon and titanite (HOM).
At Case Collina, Pitigliano, Grosseto Province, Tuscany, Italy, ekanite occurs in volcanic ejecta, associated with quartz, feldspar and pyroxene (HOM).
At the type locality, Ehiliyagoda, Ratnapura, Ratnapura District, Sabaragamuwa Province, Sri Lanka, ekanite is a detrital mineral (HOM).
