The higher the specific surface area of the targeted mineral, the finer the size of the particle and hence very speedily it gets affected by chemical weathering processes as reported by Polynov et al., in the year 1937 [5], and Merrill et al., in the year 1906 [2]. The enhancement of the specific surface is inversely proportional to the material particle diameter. It has been reported that sequence of weathering are different in case of particle with fine size in comparison to that of coarsely sized particles. For example, due to effect of specific surface the rate of weathering of volcanic ash is faster in comparison to lava. This happens due to the larger surface area subjected for processes for weathering.
