A new sedimentary log for the uppermost Turonian – lower middle Coniacian section is drawn and combined with previously published logs for the upper Coniacian to lower Campanian. The compiled isotopic record incorporates 713 new sample data along with recently published δ¹³C_car_b values from the section, and the calcareous nannofossil biostratigraphy is supported by the detailed analysis of 68 samples, using both semi-quantitative and quantitative abundance data. The local confidence in the record of biohorizons in the section and their supra-regional reliability are addressed. These include the highest and lowest occurrences of index species, but we additionally critically assess the stratigraphic use of highest and lowest consistent occurrences and the Base and Top of taxon acme levels. Three commonly used zonal and two subzonal markers are shown to be unreliable but 10 secondary events show high reliability for correlation. Carbon isotope stratigraphy, supported by macrofossil and microfossil biostratigraphy, allows for precise correlations to other European sections like Trunch, eastern England, and Salzgitter-Salder and Lägerdorf, northern Germany. Our integrated stratigraphic approach thus allows for a more accurate assessment of biozonation schemes and chemostratigraphy. In particular, this study provides a valuable resource for the refined stratigraphic expression of Coniacian, Santonian and Campanian stage boundaries and large-scale correlation of southern England to Global Stratotype Sections and Points (GSSPs).</div></div>","PeriodicalId":55207,"journal":{"name":"Cretaceous Research","volume":"178 ","pages":"Article 106214"},"PeriodicalIF":1.7,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145528445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 95 % predominance of Variscan U–Pb rutile ages in all samples and the high/ultrahigh temperatures of metamorphism exclude the Neoproterozoic greywackes and granitoids of the Lusatian Massif and the granitoids of the Jizera–Krkonoše Massif in the northeast as sources. Potential proto source rocks were high-grade metamorphic rocks similar to those today exposed within the gneissic-migmatitic Góry Sowie Massif, ca. 120 km east of the depositional area. Since the late Devonian, this massif was uplifted, reaching the surface in late Carboniferous times. Consequently, the widespread Permo–Carboniferous Variscan molasse is the major sediment source for the Cretaceous sandstones, which thus were deposited during at least their 2nd sedimentary cycle.

Key identified carbon isotope events include the Mid-Cenomanian Event 1 (MCE 1), the Oceanic Anoxic Event 2 (OAE 2) at the Cenomanian/Turonian boundary and the Pewsey Event in the middle Turonian. The findings of this study corroborate and revise previous chemostratigraphic definitions in the study area, while also demonstrating a coeval origin of different lithostratigraphic units within the Ajlun Group. On the Arabian Plate scale, a detailed (3rd order) sequence stratigraphic correlation is made between Jordan and time-equivalent strata from the well-studied Natih Formation in Oman. These correlations help to evaluate the relative contributions of eustasy and tectonics on different plate tectonic settings, since the northeastern and eastern margins were heavily influenced by tectonic processes associated with the closure of the Neo-Tethys Ocean. In Oman, the creation of increased accommodation space (ca. 40 m) is observed relative to Jordan commencing in the interval between the MCE 1 and OAE 2. This suggests the onset of tectonic precursor events in Oman during the middle to late Cenomanian interval before the main tectonic phase in the Turonian, resulting in the termination of shallow water carbonate deposition.
