Abstract: In this paper, an environments and their interpretation of platform carbonates underlying the sedimentarytectonic sheets exposed on the Bozburun (Marmaris, Muğla) peninsula have been explained.Ptatform carbonates, at the base, begins with replacement dolomites being generally coarse crystaline. These passes upwards pelloidals. Packstönes and wacestones occured in the subtidal environments. Abudant bearing pelloidal carbonates have been most probably sedimented in the shelf lagoon. The sections of platform caibonates exposed on thesouth of study area are represented by loferitic siklothems upward deepening consisting of collapse breccia, algal crustand mats, abudant bioclast bearing limestones, from bottom to top, respectively. This facies suggesting periodic relativechanges of sea-level on the immediate backreef or bank-ende of the carbonate platform.
