If a clear rhombic cleavage block is placed over a point and observed from the top, two images of the point are seen through the calcite crystal. This is known as double refraction. Is CaCO3 Rhombohedral?

WebIt occurs in minerals that are crystallographically twinned, or which have been stressed by pressure. It is usually not as well, or regularly, developed as cleavage surfaces - … Web#MineralMonday! Calcite is found across #Wyoming in a variety of geological environments. It often forms crystals w/6–12 faces & may occur as finely crystalline masses w/perfect rhombohedral cleavage, in masses w/rhombohedral cleavage, or as stains. #geology #mineral #calcite resources derived from living things
