Caliche

The growth of discrete carbonate nodules requires some element of displacive growth, which is triggered in non-carbonate hosts by the inability of calcite to form adhesive bonds with non-calcitic grains such as silica. However, in carbonate-rich hosts calcite forms cohesive bonds with other carbonate crystals (Chadwick and Nettleton, 1990).

Carbonate Classification

Embry has modified Dunham's classification and Klovan (1971) to include coarse grained carbonate s (above figure). In their revised scheme, a wackestone in which the grains are greater than 2mm in size is termed a floatstone and a coarse grainstone is called a rudstone. Both terms are extremely useful in description of limestone s.

Calcite vs Dolomite

Dolomite, on the other hand, has a more laid-back kind of luster. It usually has a pearly or matte finish, which is less flashy. If calcite is like a shiny glass window, then dolomite is more like a pearl or a smooth pebble. Its luster is softer and doesn't reflect light as brightly as calcite.
