Сторінка 59 - In a later statement55 the same author observes that the fact of prime significance geologically seems to be that, by a process of simple chemical exchange, the metal may be removed from solution and fixed in the solid state, and thus concentrated by contact with even the most stable of the silicates. The bases most commonly replacing the metals in these processes are potassium, sodium, magnesium, and calcium.
