Palaeoenvironmental interpretation of some deposits of the Cretaceous/Paleogene (K/Pg) limit in Sierra del Rosario, Western Cuba
Keywords:
Cacarajícara Formation, microfossils, evidence of impact, paleoenvironment.Abstract
One of catastrophic origin deposits associated with the Cretaceous / Paleogene limit in Western Cuba is the Cacarajícara formation. The sedimentological characteristics of the materials present in three no very visible outcrops of the mentioned formation are specified in the article with the purpose of clarifying the deposition of materials, after the impact of the Chicxulub asteroid at the end of the Cretaceous. Several methods were applied: bibliographic review, field work and megascopic description of rocks, which includes the petrographic and micropaleontological analysis of its components. As a result, a more exact approximation to the deposition conditions of these materials after the impact was obtained and its relation with the geological events, which revealed an interpretation of the existing palaeoenvironmental conditions from the study of the sedimentary processes.Downloads
