Zircon an overview ScienceDirect Topics

Zircon is a widely occurring mineral, with the chemical formula ZrSiO 4.It has a tetragonal crystal structure (space group = I4 1 /amd, a = 6.607(1) c = 5.982(1)) that is commonly reflected in the habit of zircon crystals (Fig. 1).Pure ZrSiO 4 is colorless, but trace element impurities can give rise to color. Brownish and “hyacinth” colors are common; the latter and other colored varieties
