Sandstone Petrology and Tectonostratigraphic Terranes of the Northwestern Thrace Basin, Turkey

Tectonostratigraphic study of the sandstones of the Hamitabat Group (Yenikoy and Deoirmencik Formations) of the NW Thrace Basin is described based on petrological studies of samples from six boreholes. Detrital modes determined by the Dickinson Point-Count method for the sandstones of Hamitabat Group are as follows: % Q_tFL_t = 46-35-20; %Q_mFL_t= 47-35-19; %Q_pL_vL_s= 57-12-26 (for the sandstones of the DeOirmencik Formation), and Q_tFL_t = 60-18-23; %Q_mFL_t = 59- 18-25; % Q_pL_vL_s= 62-13-24 (for the sandstones of the yenikoy Formation). No significant compositional, dingenetic differences exist among the sandstones of Hamitabat Group counted.

The sandstones of the Hamitabat Group were likely derived from the deeply dissected magmatic arc and recycled orogen provenance.
