Marble, crystalline limestone and calc-silicate rocks are emanated from calcareous sediments and locally contain quartzite and ultramafic rocks.When sedimentary and diagenetic limestones undergo metamorphism, the calcite is frequently recrystallized and tends to become coarsely crystalline. The resulting rocks are calcite marbles. Some calcite marbles, however, appear to have had dolostone rather than limestone precursors; i.e., theFigure 5.3.1 5.3. 1: Enlarged image of frosted and rounded windblown sand grains.
