According Jackson et al., in the year 1948 [37], it was reported that the chemical weathering rate is dependent on the mineral specific nature. Minerals specific nature is highly significant for determination of rate and course of weathering, which can be arranged as per the stability of the minerals. Searle et al., in the year 1923 [52–53], reported that nature of rock significantly affected the weathering rate. As per Stephens et al. [54–56], depending on the weathering ease, there is no such considerable rock classification, with an exception for basalt which is considered as one of the rock which undergoes weathering very easily and the presence of high amount of silica causes slow weathering process. According to specific minerals, feldspars undergoes chemical weathering faster than quartz and slower than ferromagnetic minerals; calcite is more resistant to chemical weathering in comparison to gypsum. According to Goldich et al., in the year 1938 [38], it was reported that plagioclase undergoes chemical weathering faster than potassium feldspar.
