                                     • A broad endothermal effect for the dehydration of consti-
                                        tutional water (partly being masked by the exothermal
                                        effect).

                                     • An endothermal effect for the decomposition of the
                                        dolomite followed by an exothermal trend for the crystal-
                                        lization effect.
