“…The latter authors contend that some of the occurrences of dark limestone and rhythmically layered marble associated with the scant record of Palaeozoic ophiolites may represent inorganic CaCO 3 deposition on the deep seafloor . This observation would lend credence to the hypothesis of Berner and Mackenzie (2011) mentioned previously that there was inorganic accumulation of carbonate in the Palaeozoic deep sea . The accumulation of calcite in submarine basalts is of further importance to the record of Ca accumulation in the deep sea .…”

“…For the Phanerozoic carbonates, Figure 4 . 1 shows the carbonate preserved (the survival rate) versus the burial flux of carbonates on the sea floor as calculated from the model GEOCARB III (Berner and Mackenzie, 2011) . Notice that much of the carbonate buried has been lost from the rock column, mainly, but not exclusively, by subduction .…”

“…Note that both the preserved rate and the burial rate curves converge to the same value at t = 0. This provides a check on the accuracy of calculations of the two entirely independent methods (after Berner and Mackenzie, 2011 nearly pure aragonite and calcite . This has been the case for at least much of the Cenozoic .…”

“…Mass balance models for the Cretaceous (Locklair et al, 2011) suggest that elevated rates of carbonate burial (burying relatively isotopically heavy carbon) could have dampened changes in δ 13 C DIC expected from elevated organic carbon burial rates (Weissert and Mohr, 1996;Föllmi, 2012). Indeed through the Late JurassicEarly Cretaceous transition elevated rates of carbonate burial and preservation are observed (e.g., Mackenzie and Morse, 1992;Berner and Mackenzie, 2011). For example, during the Late Jurassic carbonate sedimentation became dominant over wide parts of the northern Tethys (Rais et al, 2007), with the expansion and development of new reef sites (Leinfelder et al, 2002;Cecca et al, 2005).…”

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.

“…Similarly, as suggested by Brasier (2011), the advent of vascular land plants, and thus of high pCO 2 soils, would also have increased the rate of dissolution. Finally, the GEOCARBSULFvolc mass balance model of Berner & Mackenzie (2011) indicates considerable loss of carbonate rock mass over time, albeit especially of pelagic carbonates.…”

Using the voids to fill the gaps: caves, time, and stratigraphy

Karstification produces a unique and spatially complex architecture of accommodation space for the accumulation of later sediments. The sedimentary record within caves can act as a repository for stratigraphic and palaeoenvironmental information that has been locally removed by subsequent surface erosion. Caves and karst also allow for the preservation of biota not usually found in the fossil record. Pennsylvanian palaeokarst from Illinois, USA, illustrate the potential of ancient caves as a home for 'lost stratigraphy'. These palaeocaves have dissolutional features associated with contemporaneous sediment influx (paragenesis), indicating that speleogenesis and cave sediment deposition were synchronous. These features also provide evidence of changing water tables. The fill within the caves suggests multiple flood events on the surface. The enclosed biota contains rare upland plants, such as conifers, as well as scorpions. Both plants and animals preserve original organic constituents. The presence of charcoal, as well as diagnostic polyaromatic hydrocarbons, point to wildfires and thus dry episodes on the land surface. The cave fills are outliers from correlative formations in the region. The filled voids of these ancient caves thus fill palaeontological, palaeoenvironmental, and stratigraphic gaps.
