- Abstract
Casimcea Plateau is an uplifted (exhumated) peneplain cut in Proterozoic green-schists and one of the oldest tectonic units around the Black Sea. Despite its overall monotonous physiognomy, the plateau is crossed by Casimcea Valley and presents a seaward façade to the east which preserves (sub)horizontal surfaces as testimonies of the paleoenvironmental changes (sea level and climate). This research aims to identify the marine and fluvio-marine terraces and to define their vertical distribution based on the morphometric analysis of two study sites (north - Ceamurlia; south - Tașaul Lake) using EU-DEM. 6 levels were identified as possible marine terraces within the 2-50 m altitude range and also some inferences were made concerning the age of the lower three levels. Also, the present work highlights a differential (stronger) uplift of the northern sector between Peceneaga - Camena and Ostrov - Sinoe faults reflected by both the elevation difference of 5-6 m between the terraces staircases identified at the two sites and by the elevation gaps analysed on an array of cross-fault transects carried on over Ostrov - Sinoe fault.
