The Specific Gravity for bytownite varies between 2.74 and 2.75. The Refractive Indices ranges are nα=1.563 - 1.572, nβ=1.568 - 1.578, and nγ=1.573 - 1.583. Precise determination of these two properties with chemical, X-ray Diffraction , or Petrographic ( Birefringence and Optic Angle ) analysis are required for identification. Bytownite occurs in Gabbro Intrusion s and in Metamorphic complexes. The mineral was first described in 1835 and named for an occurrence at Bytown (now Ottawa ), Canada . REFERENCES
