Abstract The palynological investigation was carried out on the Woodford Shale and Sycamore Limestone samples from Interstate 35 roadcut section (I-35) on the south flank of the Arbuckle Anticline (Oklahoma, USA). All samples were collected from the 54 m long section. According to palynostratigraphy, the section was tentatively divided into three stages: Frasnian, Famennian and Tournaisian but due to poor miospores representation it was not possible to establish any single miospore zone. All sam...

Abstract Here, the Lower Permian, post-glacial fossiliferous Lontras black shales from the Parana Basin (southern Brazil) are studied using integrated palynological, geochemical and petrographic methods for the first time in order to decipher the prevalent palaeoenvironmental conditions during their sedimentation. These black shales were deposited in a restricted marine environment. Inorganic geochemical data (U/Th ratios, authigenic uranium, molybdenum), organic geochemical data (total organic ...

The mineralogical and chemical compositions of Lower Carboniferous (Tournaisian) marine black shale from the Kowala quarry, the Holy Cross Mountains, Poland, were investigated. This study focuses on disturbances in palaeoenvironmental proxies caused by palaeoweathering, which progressively changed the major and trace element abundances. Palaeomagnetic investigations reveal that the Devonian – Carboniferous succession was weathered during the Permian-Triassic by the infiltration of oxidizing flui...

Integrated biostratigraphical, microfacial and geochemical studies of the Lower Kellwasser Event in the Plucki succession (southern Poland) provide details about redox conditions during the deposition of this horizon in the deep-shelf Łysogory basin of the Holy Cross Mountains. The environment is characterized by calm sedimentation and soft, muddy carbonate substrate. However, microfacies changing from wackestones to grainstones, the presence of crushed or current-oriented nautiloid shells and t...

Abstract Pyrite geochemistry (isotope and trace element composition, degree of pyritization, S/C org ratio) was used in context of selected lithogeochemical parameters (major and trace elements, including sulphur, organic carbon, and δ 13 C of carbonate carbon) to constrain fluctuations in depositional conditions during the Early to Middle Frasnian carbon isotopic perturbation (punctata Event) in the Kostomloty Basin, Poland. Based on the ratio between the sum of oxyanionic elements and transiti...

Abstract The coupled high-resolution carbon isotope data from whole-rock limestone and organic matter samples of the transitans (Early Frasnian), punctata and the earliest hassi Zones (Middle Frasnian) from the South Polish carbonate shelf successions reveal the presence of a large, multi-part δ 13 C excursion, one of the largest known carbon cycle disturbance of Devonian period. This Early–Middle Frasnian (E–MF) δ 13 C perturbation consists of two positive excursions (a minor event I and a majo...

Abstract The Upper Famennian Annulata Black Shales are exposed in the deep-shelf successions of the famous Kowala Quarry and the Ściegnia outcrop in the Holy Cross Mountains, Southern Poland. At Kowala, the twin Annulata anoxic events are manifest as two organic-rich (TOC up to 23 wt.%), finely laminated, fossiliferous black shales, each up to 0.6 m thick, separated by marl and massive or nodular limestone layers. The bituminous interval is condensed in the Ściegnia outcrop to a single 10 cm thi...

Abstract Geochemical and palynological investigation of the Lower to Middle Frasnian reef-to-basin succession at the well-known Kowala Quarry (Holy Cross Mountains) demonstrates the variable character of organic matter (OM) deposited in different oxidative–reductive conditions. During sedimentation of the basinal deposits, anoxic conditions in the water column prevailed. In the organic-rich sediments deposited during the Palmatolepis punctata Zone (set D), anoxia occurred in the photic zone, as ...
