Thermogravimetry and differential thermal analysis have been applied to the study of peats from the main Spanish basements. The results obtained show that the degree of transformation of the organic matter increases as the depth of the peat increases. The intensity of the weight loss corresponding to the first exothermic effect (directly related to the carbohydrate content of the sample, and inversely related to the content of humic compounds) is, in the case of the peats with a high degree of transformation, strongly influenced by the nature of their humic acids. On the other hand, the displacement of this exothermic effect towards lower temperatures is directly related to the ash content of the samples.
