“…This study confirmed the various lithology of the Dvoynitsa Formation -three lithological types were recorded. Their complex spatial relationships, established in other parts of Eastern Balkanides (Vangelov, Sinnyovsky, 2011) and the Dolna Kamchia Basin (Valchev et al, 2018;Valchev, Dimitrov, 2019) were observed in the Solnik area, as well. The presence of two members (the Gebesh and Armera) was proved.…”

Based on lithostratigraphic reinterpretation of five borehole sections and lithostratigraphic interpretation of two seismic profiles, new data on the Dvoynitsa Formation’s lithology, subdivision and spatial distribution were obtained. The Armera and Gebesh Members were recognized in the area of the villages of Solnik and Bardarevo, as their spatial relationships and distribution are visualized by drawing up of four geological cross-sections.

“…Recently, we established that, in the Dolna Kamchiya Basin, the Dvoynitsa Formation is composed of four lithological types (Valchev et al, 2018b): (i) clast-to matrix-supported conglomerates (sandy and clayey debrites); (ii) thick-bedded sandstones; (iii) rhythmic alternation of thin-bedded sandstones, marls and shales (thin-rhythmic turbidites); and (iv) brown-reddish and greenish clays and marls with thin interbeds of fine-grained sandstones. The former two lithological types were referred to the Armera Member, the third one to the Gebesh Member, and the latter one to the Goritsa Member.…”

“…The former two lithological types were referred to the Armera Member, the third one to the Gebesh Member, and the latter one to the Goritsa Member. On the basis of planktonic foraminiferal data, we determined the chronostratigraphical range of the Dvoynitsa Formation as lower Ypresian-middle Lutetian (Valchev et al, 2018b). In the Eastern Balkanides, the unit ranges from the uppermost Maastrichtian to the middle Lutetian (Vangelov and Sinnyovsky, 2011).…”

“…They exhibit clear lithological features and sharp boundaries. The spatial relationships of the three members of the Dvoynitsa Formation were visualized by 3D lithologic model (Valchev et al, 2018b), and therefore in the present model the unit is represented as a unified body. The similar lithology (loose terrigenous successions) and the indistinct boundary between them forced us to merge the Beloslav and Dikilitash formations in one unified body.…”

This study is based on primary lithological data from 96 boreholes and lithostratigraphic interpretation of 17 seismic profiles from the onshore part of the Dolna Kamchiya Basin, which belongs to the onshore sector of the Moesian Platform and comprises the south-easternmost part of the Southern platform zone. Nine formal Paleogene lithostratigraphic units were recognized (the Byala, Komarevo, Dvoynitsa, Beloslav, Dikilitash, Aladan, Avren formations, the Dolni Chiflik Member of the Avren Formation, and the Ruslar Formation). For visualization of their spatial relationships and revealing the deep structure of the basin, a 3D lithological model was created. In addition, new data on the lithology, thicknesses and ages of the units were provided.

The present article aims to provide new data on the spatial distribution and lithological features of the Paleogene lithostratigraphic units in the Goren Chiflik Horst, which is part of the Moesian Platform in Eastern Bulgaria. Eight formal Paleogene lithostratigraphic units were recognized on the basis of primary lithological data derived from 29 borehole sections. They are as follows: the Komarevo Fm. (Thanetian), the Beloslav Fm. (Ypresian), the Dikilitash Fm. (Ypresian), the Aladan Fm. (Ypresian), the Avren Fm. (uppermost Ypresian–lowermost Priabonian), the Dvoynitsa Fm. (Lutetian), the Dolni Chiflik Mb. of the Avren Fm. (Bartonian–Priabonian), and the Ruslar Fm. (Oligocene). Their spatial distribution and relationships are visualized by drawing up 11 geological cross-sections. Additional data on their lithology, thickness, boundaries and age are also given.
