Sørensenite was first observed in 1962 in the Kvanefjeld area in the north-westernmost part of the Ilimaussaq complex (Greenland), on the north-east slope of Nakalaq. Sørensenite occurs in hydrothermal veins in naujaite in association with analcime, microcline, sodalite, neptunite and aegirine.
• Form: Lath-shaped or acicular crystals.
• Relief: Moderate.
• Color: Colorless.
• Twinning: Complex.
