It may contain considerable amounts of magnesium carbonate (dolomite) as well; minor constituents also commonly present include clay, iron carbonate, feldspar, pyrite, and quartz.

Limestone can also form from the evaporation of water in caves and other confined spaces.Eight specimens with different dimensions (L × W × H) of the limestone rocks from the study area were prepared by disc saw machine; then dried in oven at 105°C for 24 hr.
