Here are some examples:
* Limestone: Primarily composed of the mineral calcite (calcium carbonate).
* Quartzite: Primarily composed of the mineral quartz (silicon dioxide).
* Marble: Primarily composed of the mineral calcite (calcium carbonate).
* Gypsum: Primarily composed of the mineral gypsum (hydrated calcium sulfate).
* Rock salt: Primarily composed of the mineral halite (sodium chloride).
* Rock gypsum: Primarily composed of the mineral gypsum (hydrated calcium sulfate).
It's important to note that even these monomineralic rocks often contain trace amounts of other minerals, but the dominant mineral makes up the vast majority of the rock's composition.
