* Limestone: Composed primarily of the mineral calcite (calcium carbonate, CaCO3).
* Quartzite: Composed primarily of the mineral quartz (silicon dioxide, SiO2).
* Marble: Composed primarily of the mineral calcite (calcium carbonate, CaCO3).
* Gypsum: Composed primarily of the mineral gypsum (calcium sulfate dihydrate, CaSO4·2H2O).
* Halite: Composed primarily of the mineral halite (sodium chloride, NaCl).
While these rocks are predominantly made up of a single mineral, they often contain trace amounts of other minerals. However, the dominant mineral is what gives the rock its defining characteristics.
There are many other examples of monomineralic rocks. It's important to note that some rocks, like granite, are made up of multiple minerals.
