“…According to Vachard and Maslo (1996), the last appearance of Eostaffella ikensis, based on the data given in Einor et al (1979), nearly corresponds to the Serpukhovian-Bashkirian boundary. Similarly, Vdovenko et al (1990) reported the stratigraphic range of this taxon from the Russian Platform as ranging from the Upper Visean to the Serpukhovian-Bashkirian boundary, including the Zapaltyubinsky Horizon. The lower boundary of this zone is marked by the first appearance of E. postmosquensis in this study.…”

“…The lower boundary of this zone is marked by the first appearance of E. postmosquensis in this study. In earlier studies, Vdovenko et al (1990) and Vachard and Beckary (1991) reported the first occurrence of E. postmosquensis in the Serpukhovian, below the Zapaltyubinsky Horizon. However, in more recent studies Maslo and Vachard 1997;Krainer and Vachard 2002;Kulagina et al 2009) the first occurrence of E. postmosquensis was reported at the base of the Zapaltyubinsky Horizon.…”

“…The most characteristic features of this zone are the first occurrences of Plectostaffella bogdanovkensis and P. jakhensis at or very close to the lower boundary. According to Vdovenko et al (1990) and Vachard and Maslo (1996), Eostaffella ex gr. ikensis became extinct close to the Serpukhovian-Bashkirian boundary.…”

Facies (2011) 57:705-730 707 This zone is considered to be equivalent to the Zapaltyubinsky Horizon in the Russian Platform and Donets Basin Shcherbakov 1997), to the upper part of the E2 Zone in Western Europe (Vdovenko et al 1990;Shcherbakov 1997) and to the Ustsarbaisky Horizon in Urals (Rui et al 1996) (Table 1).…”

“…In the Donets Basin, it was placed at the base of the E1 limestone (Aisenverg et al 1979;Einor et al 1979;Rotai 1979;Semichatova et al 1979). Several important studies adopted this scheme (Lys et al 1978;Vachard 1980;Altıner 1981;Vdovenko et al 1990;Vachard and Beckary 1991). However, following the Carboniferous Meeting held in 1995 (Kagarmanov and Kossovaya 1997), the boundary in the former Soviet Union was adjusted downward to the contact between Zapaltyubinsky and Voznessensky horizons of the Russian Platform, the base of the Bogdanovsky horizon of Urals and the base of the C 1 d 2 Zone of the Donets Basin.…”

The Aladag Unit is one of the main tectonic units in the Tauride Belt, located in southern Turkey. It includes a continuous Paleozoic carbonate sequence encompassing the mid-Carboniferous boundary, with outcrops being especially well exposed in the Hadim region. The boundary succession lithology is mainly composed of carbonates with intercalated quartz arenitic sandstone layers. Based on foraminifers, four biostratigraphic zones have been defined in the interval from the Upper Serpukhovian to the Lower Bashkirian. These zones are, in ascending order: the Eostaffella ex gr. ikensis-E. postmosquensis Zone (Zapaltyubinsky Horizon, Upper Serpukhovian); the Plectostaffella jakhensis-P. bogdanovkensis Zone, and the Millerella marblensis Zone (Bogdanovsky Horizon, lower Bashkirian); and the Semistaffella sp. Zone (Syuransky Horizon, lower Bashkirian). The mid-Carboniferous boundary occurs between the Eostaffella ex gr. ikensis-E. postmosquensis Zone and the Plectostaffella jakhensis-P. bogdanovkensis Zone. Boundary beds are characterized by eight, repeatedly occurring microfacies types, namely: (1) coated crinoidal packstone; (2) coated bioclastic grainstone; (3) oolitic grainstone; (4) oolitic packstone-grainstone; (5) intraclastic grainstone; (6) mudstone-wackestone; (7) quartz-peloidal packstone; and 8) quartz arenitic sandstone. Based on microfacies stacking patterns, various types of shallowing-upward cycles have been recognized. Depositional sequences and sequence boundaries are correlatable with those described from North America and Russia and Carboniferous global sea-level curves. The duration of cycles has been estimated as 100 ky, suggesting that cycle periodicities correspond to the Milankovitch eccentricity band.

The biostratigraphy and sedimentological evolution of the Tournaisian±ViseÂ an (T±V) transitional strata in South China (Guangxi) have been investigated. The sediments were deposited on a carbonate platform and in slope and basinal environments. In the T±V transitional strata, six foraminiferal associations have been distinguished which allow correlation between the shallow and deep water deposits. A careful examination of the evolutionary stages of the foraminifer Eoparastaella provides a more accurate criterion for the de®nition of the T±V boundary, but does not signi®cantly modify the historical one. The distinction of two morphotypes is based on the elevation of the last whorl and the peripheral outline. Tournaisian specimens of Eoparastaella have a well rounded periphery (morphotype 1) contrasting with the subangular periphery of younger ViseÂ an specimens (morphotype 2). A coecient can be deduced from simple biometric measurements for more precisely de®ning the T±V boundary.The sequence stratigraphy of the T±V strata in South China has been reconstructed by combining biostratigraphical and sedimentological data. It allowed the correlation of the T±V transitional strata between the platform area and the slope and basinal locations. Late Tournaisian strata were deposited during a highstand systems tract. Near the end of the Tournaisian, a major drop in relative sea-level led to the development of an unconformity in the platform area. Lowstand deposits formed during latest Tournaisian time in the basin where a detailed biostratigraphic framework has been devised. Sediments deposited during the ensuing transgressive systems tract overlie the late Tournaisian highstand sediments in the platform area and the latest Tournaisian lowstand deposits in the basin. A major drop in relative sea-level near the end of the Tournaisian has been recognized worldwide. Therefore, the possibility of using the sequence stratigraphy of the T±V strata in South China for worldwide correlations should be investigated.

Famennian Fusulinina (Foraminifera) from the Holy Cross Mountains (central Poland)

Calcareous foraminifers representing 9 species and 5 genera were investigated in two Famennian sections located in the south‐western part of the Holy Cross Mountains (HCM), central Poland. They constitute redeposited material that, together with crinoids and calcareous algae, comprise the dominant component of limestone turbidite beds intercalated with deep‐marine marly sediments. The calcareous material was redeposited from an unknown carbonate platform located probably to the south of the HCM area. The first appearance data of foraminifers, mainly from the quasiendothyrid group, correlated to the Standard Conodont Zonation, indicate a diachronous appearance of the same species in different parts of Europe due to a migration delay from the foraminiferal evolutionary centre located in the south‐eastern shelves of Laurussia in the neighbouring areas. As a result, the Moravian foraminiferal zonation, where index taxa appeared in similar stratigraphic intervals, was chosen as the most applicable to the stratigraphy in the central Polish area. The Quasiendothyra communis–Eonodosaria evlanensis Interzone, the Quasiendothyra communis–Quasiendothyra regularis Zone and Quasiendothyra kobeitusana–Quasiendothyra konensis Zone were distinguished, respectively, in the HCM sections.
