Description :
The bolsas mostly are accompanied by a large number of Quaternary reef terraces in East Cuba. Raised beaches are not only the result of eustatic changes but also of isostatic or tectonic processes. Tectonic uplifts occurred frequently during the Cainozoic era in Cuba and in the Caribbean as well. Both of these processes – uplifts and sea-level changes – involve a particular problem closely linked with the reconstruction of bolsa stages. That means it is necessary to differentiate not only regionally but also chronologically. Evidence suggests that the sediments of the bolsas keep records of a long landscape history and even of eustatic medium-term sea-level changes. The AA. assume that the conditions of the sedimentation changed gradually during the course of a bolsa-cycle. Until now bolsas have not been acknowledged regarding their geo-archive significance. The goal of this study is to give an overview over the bolsa phenomenon.
