Abstract


In the present paper we introduce lake Bolătău, located in Obcina Feredeului, Eastern Carpathians (Romania), with seasonally controlled sedimentation and significant potential for generating precipitation sensitive proxy record. Two sediment cores were compared against each other in order to achieve a better understanding of the lateral discontinuity of observed microfacies and an accurate interpretation of the sedimentological data.


Keywords


precipitation, microsedimentology, annually laminated sediments
