Beypazari nakolitlerinde Ca, Mg, K ve Rb dagilimi

The presence of Ca, Mg, K and Rb in Nahcolites from Beypazari (Ankara), have been investigated and their statistical features have been determined. The role of these elements in the formation of nahcolite has been discussed by taking into account two different types of crystallization. The increasing and continual Ca supply and fluctuating Mg supply are noted. The contents of K and Rb of this soda mineral, which had been deposited on the top of the trona horizons as a result of decreasing Na supply, have shown strong positive correlation. -after English summary
