The following consequence is: such an introductory diagram temperature versus . of a peak can be only valid for one set of investigation conditions. If you vary the heating rate, for example, you will get a shifting of the data. Therefore

Influence of the Chemical Composition on the Temperatures of Structural Transformationsormation temperature of this witherite containing Ca and Mg and of norsethite demonstrate that this second transformation temperature is apparently being influenced by the Mg contents incorporated into the witherite resp. norsethite structure.

Contribution to the Classification of Chloriteslorites will not be successful to the same extent as in optical investigations of other mineral groups-, “in spite of the optimistical estimation of some authors” (.). Therefore as a method additional to optics . recommends “the differential thermal analysis and the possibilities of classification latent in this method”.
