How do minerals occur in sedimentary rocks?

Minerals occur in beds or layers in sedimentary rocks. They are formed as a result of deposition, accumulation, and concentration in the horizontal strata. For example – coal, which has been formed as a result of long periods under great heat and pressure. Minerals like gypsum, potash salt, and sodium salt are formed as a result of evaporation.


NOTE - The formation of minerals is subject to various conditions, physical as well as chemical. Minerals are formed under igneous and metamorphic rocks as well as sedimentary rocks.
