How many cleavages does calcite have
WebDec 16, 2024 · Like halite, calcite has three good cleavages. But, unlike halite, the cleavages are not perpendicular to each other. So calcite cleaves into shapes called rhombs. This photo shows a bunch of calcite cleavage fragments. Compare the shape of these fragments with the clear calcite shown in Figure 3.38.
