How are minerals formed in sedimentary rocks?

Answer:

  • In sedimentary rocks, a number of minerals occur in beds or layers.
  • They have been formed as a result of deposition, accumulation and concentration in horizontal strata.
  • Coal and some forms of iron ore have been concentrated as a result of long periods under great heat and pressure
  • Another group of sedimentary minerals includes gypsum, potash salt and sodium salt. These are formed as a result of evaporation especially in arid regions.
