Ammonites, inoceramids and stable carbon isotopes of the Cenomanian–Turonian OAE2 interval in central Europe: Pecínov quarry, Bohemian Cretaceous Basin (Czech Republic)

Distribution and significance of rare earth elements in Cenomanian-Turonian phosphate components and mudstones from the Bohemian Cretaceous Basin, Czech Republic

“…The oldest sediments in the BCB are of fresh water origin and were deposited in the most depressed areas (Žítt et al 1998). The Cenomanian-lower Turonian sequence is represented by the Peruc-Korycany Formation (Cenomanian) and the Bílá Hora Formation (uppermost Cenomanian-lower Turonian) (Čech et al 2005(Čech et al , Košťák et al 2018. The Peruc-Korycany Formation consists of three members: Peruc, Korycany (Čech et al 1980), and Pecínov (Uličný 1997).…”

“…The Pecínov Member at Pecínov quarry was subdivided by Uličný et al (1997) and Košťák et al (2018) into four principal units P1-P4, which are bounded by well-recognizable, erosional and/or burrowed surfaces. The sequence description has recently been updated by Košťák et al (2018). Unit P1 is placed at a major erosional…”

“…Most samples (see Fig. 1 for geographic location) for this study come from the upper part of Pecínov Member (unit P3; about 2 m thick and unit P4; about 1 m thick) and the lowermost part of the Bílá Hora Formation (unit BH 1; 0.6 m thick) exposed at Pecínov quarry (see Uličný et al 1997 andKošťák et al 2018 for units terminology and stratigraphic location), and the Lower Coprolite Bed of the Teplice Formation at Úpohlavy quarry (see Wiese et al 2004 for stratigraphic location). Several samples were also collected from the basal part of the Bílá Hora Formation (Plaňany quarry), Teplice Formation (Nová Ves quarry and Býčkovice roadcut; Vodrážka et al 2009).…”

“…In addition, some samples from subsurface sections of drilled wells were also included. Sampling at Pecínov quarry covered the base of the N. juddii Zone at the base of unit P3 (sensu Košťák et al 2018…”

“…The Bílá Hora Formation at Pecínov quarry was described by Uličný et al (1997). A more detailed description of the basal portion of the Bílá Hora Formation is presented by Košťák et al (2018). Unit BH 1 is 0.6 m thick, comprised of strongly glauconitic, grain-to matrix-supported quartz siltstone that rests on a strongly bioturbated, irregular surface.…”
