Calcite and Dolomite

Calcite and dolomite are very similar minerals. Both have . The best way to tell one from the other is the acid test: a drop of 1 M HCl on calcite produces an instant, obvious fizz; a drop on dolomite produces slow or no obvious bubbling. .

Birefringence in Calcite Crystals | MicroscopyU

The tutorial initializes with a calcite crystal positioned in the center of the window, and superimposed over letters for the word Birefringence. Due to birefringence in the calcite crystal, letters seen through the mineral appear doubled. As the crystal is rotated with the Rotate Crystal slider, one of the images remains stationary.
