Title

On the Formation and Occurrence of Saddle Dolomite. Discussion

Abstract

In their paper on saddle dolomite (M.A. 81-3218), Radke & Mathis suggested that at T > 60°C, sulphate-reducing conditions and pyroelectric effects due to fluctuating T seem to favour the formation of these distorted dolomite crystals. In laboratory experiments Gregg produced saddle dolomite by reacting aragonite pelecypod fragments with MgCl2 solution containing Ca ions at 260°C for 23 hr and longer. These results demonstrate that neither sulphate-reducing conditions nor fluctuating T are necessary, although the exact role of T in distorting the dolomite lattice remains unknown.
