Protecting the Cuban Geological Heritage

ABSTRACT

In order to know and evaluate the real condition of the sites of geological interest, or geosites, in the western Cuban territory, so as o propose measures to protect and preserve them, a methodology for diagnosis and a weighted classification of the patterns established were worked out.

Due to their importance as a Geological Heritage, the lithostratigraphic units (geological formations) recognized in the

Stratigraphic Lexicon of Cuba were initially considered. These units are located as follows: 11 in Havana province; 21 in Havana City province; 37 in Pinar del Río province, and 11 in the Isle of Youth.

In the course of research and during field work, other 52 geosites were added due to their paleontologic, hydrogeologic and geomorphologic importance, as well as 7 sites of mining interest. Altogether, 159 sites were analyzed. During field work, many geosites were found to be partially damaged, 15 out of them being severely affected by human action.

Some geosites have disappeared completely, e.g. the type sites of the geological Río Rancho and Majagua formations and most of the members of the Via Blanca formation, etc.

The National Commission for the Stratigraphic Lexicon is requested to find and designate different categories of stratotypes from 17 geologic formations and their members.

It is proposed that 17 geosites in Pinar del Río, Havana and Havana City provinces and in the Special Municipality of the Isle of Youth be designated Local Monuments and other 16 geosites be designated National Monuments.
