Abstract
The invention relates to a method of characterizing and of quantifying carbon from a superficial deposit, wherein a sample of the deposit is subjected to heating in an inert atmosphere, the sample residue is subjected to heating in an oxidizing atmosphere, and quantities of HC, CO and COreleased during heating, from which standard parameters TOC and MinC, and a ratio between mineral carbon and total carbon of the sample are determined, are measured. If the ratio is non-zero, the organic carbon content is equal to the sum of TOC and of a percentage of TOC ranging between 4 and 12%, and the mineral carbon content is equal to MinC minus this percentage of TOC. If the ratio is zero, the mineral carbon content is zero and the organic carbon content is equal to the sum of TOC and MinC.
