Appendix. Position of sections Supplementary material to to Jarochowska & Kozłowski, Facies, Facies development and sequence stratigraphy of the Ludfordian (Upper Silurian) deposits in the Zbruch River Valley, Podolia, Western Ukraine: local facies overprint on the δ13Ccarb record of a global stable carbon isotope excursion The sections described below can be accessed from the west through a country road from Mel'nytsya-Podil's'ka to the village of Kudryntsi, from the south-west through a country road leading through Panivtsy to Zavalya, or from the east, along the local road no. T2323 leading from the city of Kamianets-Podilskyi to Kudryntsi. Zavalya 1 φ 48°35'40.30"N λ 26°20'47.70"E This is a laterally extensive (approx. 150 m long) outcrop on the left bank of the Zbruch River, south of the village of Zavalya. It is formed as a natural exposure in the steep valley slopes. The outcrops can be accessed from a country road leading from the village along the river or, alternatively, from the country road on the hill crest above the river, which connects Zavalya with the regional road no. T2002. Zavalya 2 φ 48°36'55.40"N λ 26°18'41.20"E The section is located 600 m south of Zavalya 1 along the Zbruch River and is exposed in a small abandoned quarry in the valley slope. It can be accessed from the same road as the Zavalya 1 section. Milivtsi–South φ 48°38'13.70"N λ 26°19'12.60"E The section is accessible in a ravine on the eastern bank of the Zbruch River, south of Milivtsi, ca. 300 m southward from the village cemetery. The ravine is cut in the slope of the river valley above the floodplain, densely overgrown with vegetation and covered in rubble. Silurian rocks exposed in this section are unconformably overlain by Miocene calcareous sandstones and rhodoid limestones. It is possible to access the outcrop by car from Milivtsi or by foot through a narrow path leading from Kundryntsi across the floodplain. Milivtsi–North φ 48°38'51.60"N λ 26°18'19.90"E The outcrop is situated on the eastern bank of the Zbruch River, between Milivtsi and Chernokozintsi. It can be reached from both villages through the road which joins them, but is hardly accessible for cars. Along the road, he massive Isakivtsy dolomites are exposed almost continuously. Above the dolomites – due to an abrupt change in lithology – the slope of the river valley becomes more gentle and is generally overgrown, with the exception of the Milivtsi-North section, which is exposed in a narrow ravine situated below the buildings belonging to the hospital in Milivtsi. However, the contact between the massive Isakivtsy dolomites and the overlying dolomitic mudstones belonging to the Prygorodok Fm. is covered by a thick layer of rubble and is not therefore accessible for examination. Kudryntsi–Castle φ 48°37'14.57"N λ 26°17'37.08"E The section is accessible on the western bank of the Zbruch River. The outcrop is a vertical wall formed in the southern side of a hill, marked by the remains of a XVII-century fortress on top of it. The outcrop starts in a slight depression, which reaches below the level of the road leading through the village of Kudryntsi, and consists of two levels which are described herein as the lower and the upper part. The interval between the top of the lower level and the bottom of the upper section is not accessible (covered with rubble and vegetation). Silurian rocks are overlain with Badenian gypsum and anhydrite deposits. The outcrop is intensively exploited by local population for building stone, resulting in that new fragments are being exposed at different times. It is possible to access the outcrop by car from the road joining Mel'nytsya-Podil's'ka with Kudryntsi, or from the left bank of Zbruch through the road T2323, with the restriction that the bridge joining the two banks is accessible to pedestrians only. Kudryntsi–Cowpath φ 48°36'55.40"N λ 26°18'41.20"E The section consists of three adjacent narrow ravines in the west bank of the Zbruch River, approximately 1200 m southward from the outcrop below the castle in Kudryntsi. The outcrops are accessible from a narrow path used by cows to access pastures lying on a floodplain to the south of Kudryntsi (see access information for the Kudryntsi-Castle section). As the dominant lithology in this section is mudstone and marlstone, it is heavily overgrown and prone to weathering, therefore a large part of the lithological profile is described based on excavations performed during present study.
