Main Article Content
Abstract
Beach rocks are well exposed deposits in the marine-coastal territory of Cuba, however, they are practically unknown and do not appear in the existing stratigraphic classifications. Since the last century, these deposits have been the object of research in different parts of the world, which have provided valuable information on their characteristics and the processes that give rise to them. In Cuba, they have been little investigated, but because they lie on the late Upper Pleistocene Jaimanites Formation and the pearly lustre still preserved on the shells and snails, they can be considered Holocene, with a diapason from contemporary still developing to older well lithified, although patches appear in the first Pleistocene terrace that could be older, genetically they are of the unnamed marine type. This work covers the entire marine-coastal territory of Cuba and is based on the author's field observations and previous research in Cuba and numerous other countries. Its aim is to draw attention to the geological-environmental interest that these deposits could have if investigated, since they constitute evidence of lithomorphogenetic processes and factors in certain coastal sectors.
