Abstract
Peat is an organic material, consisting of a light, spongy mass in which the plant components that gave rise to it are still visible. In the genetic classification of the Quaternary deposits Quaternary deposits of Cuba belong to the biogenic type. The article examines these deposits not as a mineral resource, but as traces of coastal palaeolines in the last 11700 ka of the history of geological development in the marine territory of Cuba, through their thin lenticular horizons, which alternate with other types of deposits. According to previous research peats predominate at four depth levels, with their own ages: > 14 m (probable 11.7 ka), 14-12 m (7-6 ka), 6-5 m (5.5-4.7 ka) and 3.4- 1.5 m (4.2 ka or less). The hypsometric age-position correlations should be considered as a guideline for their considered as a guideline for their application, since the values obtained are regional in nature and, moreover, are values obtained are regional in nature and, in addition, the different regions of the marine territory have been affected by neogene movements, different regions of the marine territory have been affected by neotectonic movements of different trends. What is unequivocal is that the peat deposits of the sub-seabed peat deposits are useful for the determination of coastal palaeolines and, consequently, are a valuable are therefore valuable information for reconstructing the history of the geological of the geological development of the place where they are discovered, and are an important contribution to the important contribution to the deepening of geological knowledge, which is the object of geological mapping at the of geological mapping at a scale of 1: 50 000, currently under development.
