“…The δ 13 C carb data are from bulk sediments as shown in detail in Fig. 6, excluding data from the Subpolar Urals and North Siberia (Dzyuba et al, 2013;Price and Mutterlose, 2004) and excluding the data from La Chambotte (Morales et al, 2013) and the Kimmeridgian data from the Swiss Jura (Colombié et al, 2011).

“…For example, Michalík et al (2009) documented a minor (<0.5‰) negative excursion in the latest Jurassic (Late Tithonian), whilst some Boreal records (e.g., Žák et al, 2011) show negligible variation associated with the boundary. Dzyuba et al (2013) reported a positive δ 13 C shift immediately above the Jurassic-Cretaceous boundary. The significance of Jurassic-Cretaceous carbon isotope stratigraphies is underlined by correlation needs for the yet-to-be-defined GSSP.…”

“…The low δ 13 C values of the earliest Cretaceous contrast with the more positive values obtained from the Valanginian (Lini et al, 1992;Hennig et al, 1999;Weissert et al, 1998;Duchamp-Alphonse et al, 2007;Főzy et al, 2010). Such variation has led to the idea that carbon isotopes may be useful in adding to the characterisation of the Jurassic-Cretaceous boundary (e.g., Michalík et al, 2009;Dzyuba et al, 2013;Shurygin and Dzyuba, 2015) although others (e.g., Ogg and Hinnov, 2012a) note the lack of significant geochemical markers. Changes in the Late Jurassic-Early…”

We present new carbon and oxygen isotope curves from sections in the Bakony Mts. (Hungary), constrained by biostratigraphy and magnetostratigraphy in order to evaluate whether carbon isotopes can provide a tool to help establish and correlate the last system boundary remaining undefined in the Phanerozoic as well provide data to better understand the carbon cycle history and environmental drivers during the Jurassic-Cretaceous interval. We observe a gentle decrease in carbon isotope values through the Late Jurassic. A pronounced shift to more positive carbon isotope values does not occur until the Valanginian, corresponding to the Weissert event. In order to place the newly obtained stable to relatively stable δ 13 C values, compounded by a slope which is too slight. There is no clear isotopic marker event for the system boundary. The long-term gradual change towards more negative carbon isotope values through the Jurassic-Cretaceous transition has previously been explained by increasingly oligotrophic condition and lessened primary production. However, this contradicts the reported increase in 87 Sr/ 86 Sr ratios suggesting intensification of weathering (and a decreasing contribution of non-radiogenic hydrothermal Sr) and presumably a concomitant rise in nutrient input into the oceans.The concomitant rise of modern phytoplankton groups (dinoflagellates and coccolithophores) would have also led to increased primary productivity, making the negative carbon isotope trend even more notable. We suggest that gradual oceanographic changes, more effective connections and mixing between the Tethys, Atlantic and Pacific Oceans, would have promoted a shift towards enhanced burial of isotopically heavy carbonate carbon and effective recycling of isotopically light organic matter.These processes account for the observed long-term trend, interrupted only by the Weissert event in the Valanginian.

“…However, correlation over wider areas using this method is complicated by differing facies and lithologies between boreal and tethyan areas, as well as the limited abundance of belemnites, noted in parts of the Nordvik sequence (Žák et al 2011: see the more recent work of Dzyuba et al 2013). Sadly, chemostratigraphic evidence is not very helpful in marking or bracketing a J/K boundary.…”

Abstract:In this contribution we examine and discuss recently published magnetostratigraphic data from the Nordvik section (north Siberia) around the Tithonian-Berriasian (J/K) boundary, with a special emphasis on calibration with biostratigraphy and the reliability of both the fossil and magnetic records, as well as sedimentation rates. Specifically, we discuss original new interpretations by Bragin et al. (2013) and the commentary on that work by Guzhikov (2013). We consider some limitations of the Nordvik section, and conclude that the base of M18r, because it is in a condensed part of the sequence, makes a poor contender for precise long-range correlation. We discuss the lack of ammonites at several magnetozone boundaries, and whether the bases of the local zones of Craspedites taimyrensis and Arctoteuthis tehamaensis can be used to bracket the correlative horizon of Calpionella alpina, a widespread marker in the middle of M19n.2n in Tethys.

Thin tuff beds of the Late Jurassic–Early Cretaceous Bazhenovo Formation are laterally widespread in the central part of the West Siberian Basin (ca 0.5 million km2). However, the source of the tuff beds remains unclear. The stratigraphy, geochemistry and geochronology of the tuff beds were investigated to reveal their magmatic origin and potential source region. Most of the tuff beds are recorded in member 4 and can be correlated through the Bazhenovo sequence. Thin‐section petrography and X‐ray diffraction indicate that the tuffs mostly comprise clay minerals and K‐feldspars. Less common minerals are plagioclase, quartz and pyrite. The geochemical composition of the Bazhenovo tuff beds suggests a parental magma origin of andesite/basalt, which came from volcanic arc‐related settings. Considering the results of geochemical studies along with LA‐ICP‐MS zircon U–Pb dating (141.3 ± 0.3/2.8 Ma), the palaeovolcanoes of the Caucasus region or south‐east Mongolia–North‐East China are one of the potential source regions of the tuffs. The record of these tuffs indicates the intensive volcanic eruption during the Volgian–Ryazanian, accompanied by a very low‐sedimentation rate and preservation in a reducing environment. The tuff beds have broad implications as an isochronous marker horizon and constraints for the numerical age of the Jurassic–Cretaceous boundary in the Boreal Realm.
