Safran coal section (Miocene of Turkey)

Also known as Yalova

Where: Yalova, Turkey (40.6° N, 29.3° E: paleocoordinates 41.0° N, 28.6° E)

• coordinate stated in text

When: Yalakdere Formation, Tortonian (11.6 - 7.2 Ma)

• Neogene and younger sedimentary rocks, which contain the Safran coal section, rest unconformably on pre- Neogene basement around Yalova city. These sedimentary rocks can be divided into two parts: the Kilic and Yalakdere formations. Upper Pleistocene marine terrace deposits crop out between Yalova and Karamürsel. Along its stratigraphic contact with the K›l›ç Formation, the Yalakdere Formation begins with reddish mudstone or sandy limestone-marl succession on the yellowish conglomerate-sandstone of the K›l›ç Formation. The mudstone is about 10 m thick and shows gradual transition into a white coloured marl and clayey limestone. South of Safran village, the formation is represented mainly by white, thin- to medium-bedded algal limestone (lacustrine?), and also thin-bedded limestone-marl alternation with graded-, and thick- bedded sandstone intercalations. The Yalakdere Formation may be interpreted as deposited within a low energy lacustrine-swamp environment (Emre et al. 1998).

Environment/lithology: mire or swamp; white claystone and sandy claystone

• The Yalakdere Formation may be interpreted as deposited within a low energy lacustrine-swamp environment
• The sediments of the Safran coal section are assigned to the Yalakdere Formation (Figure 2). They consist, from bottom to top, of: 100 cm coal, 40 cm white clay, 52 cm coal, 10 cm light clay, 150 cm coal (intensely folded and broken), 48 cm white sandy clay (laminated and fossiliferous), 64 cm coal, 170 cm light beige clay, 10 cm clay with chalk, 90 cm light beige clayey marl, 200 cm alternations of coaly and thin clayey beds, 200–250 cm coal, 40–120 cm beige clay, 150–180 cm alternations of coaly, peaty and clayey beds, 35 cm fossiliferous sand with overlying laminated clay, 300–350 cm fossiliferous clay and coal, 300 cm beige clay, 500 cm light brown clay. The fossils were collected from the 40 cm white clay.
