Abstract
IN 1947, McDowall and Dunn1 reported the differential thermal curves for free quartz in eight New Zealand clay deposits. They pointed out that the peaks of the α–β inversion were broader than those of quartz–alumina mixtures, and that in one case a small sharp peak at 573° C. was associated with a broader one at 555–560° C., resulting in an unusual double peak. The properties of these unusual forms of quartz are further described by McDowall and Vose2.
