Abstract
The invention relates to a method of characterizing and of quantifying carbon in a superficial deposit. The sample of the formation is subjected to heating in an inert atmosphere with at least six isothermal stages connected by a thermal gradient, the sample residue is subjected to heating in an oxidizing atmosphere, and the quantities of HC, CO and COreleased during heating are measured. A ratio of the mineral carbon to the total carbon of the sample is determined, and the at least one of the organic carbon and mineral carbon content of the sample is determined according to this ratio: (i) by accounting for an estimated quantity of COreleased by thermal cracking of the organic matter of the sample during heating in the inert atmosphere if the ratio is substantially non-zero; (ii) if the ratio is substantially zero and the mineral carbon content is zero.
