Primary Minerals In Soil

Primary Minerals The primary minerals are those which are formed owing to the crystallization of the molten magma We have already seen that the earth’s crust contains dominant amount of oxygen 4660 followed by silicon 2772 In order to achieve neutrality between the negativelycharged oxygen and the positivelycharged silicon
