EN Conodont faunas are generally sparse in Pridolito middle Givetian deposits from the Rabat-Tiflet area in the north western Moroccan Meseta. The Pridoli and Lochkovian rocks consist of dark platy limestones alternating with dark shales containing graptolites in some levels. In the over lying part of [...]

EN The Frasnian-Famennian (F-F) boundary in Central Iran has been investigated on the basis of conodont faunas (34 species and subspecies) from four sections: Chahriseh near Esfahan, and Kal-e-Sardar, Howz-e-Dorah and Ghale-Kalaghu near Tabas. The F-F boundary in the Chahriseh section is located in a o[...]

EN The paper presents a new interpretation of the geological structure and stratigraphy of the Devonian in the Świętomarz–Śniadka section. The uppermost Śniadka Formation (equivalent to the Nieczulice Formation), was described previously from the northern part of the section between exposures of the sa[...]

EN The paper give a biostratigraphic interpretation of the Emsian to Eifelian in the Łysogóry and Kielce regions of the Holy Cross Mountains, based on the different groups of microfossils: miospores, conodonts, ostracods and foraminifers. Four miospore zones were identified in the uppermost Pragian, Em[...]

EN The first occurrence of the conodont Ancyrodella rotundiloba has been used extensively for correlating the Middle-Up per Devonian (Givetian-Frasnian) boundary in sections worldwide despite many arguments as to its precise taxonomic definition. These arguments are summarised herein and three ontogene[...]

EN The conodont fauna and conodont-based biostratigraphy of a part of the Devonian succession of the Ściegnia section (Łysogóry region, Góry Świętokrzyskie Mountains [Holy Cross Mountains]) are discussed. The studied strata are composed of rhythmically bedded black shales and marly shales with intercal[...]

EN The Givetian carbonate succession of the Mzurów 49-BN borehole, SW part of the Małopolska Massif, has been divided into three lithological units: set A (Amphipora limestones), set B (micritic limestones;subdivided into subsets B1 and B2), and set C (peritidal dolomites with evaporites). The sets rep[...]

PL Przedstawiono szczegółową stratygrafię turneju i wizenu Pomorza Zachodniego w oparciu o konodonty, miospory i małżoraczki. Materiał do badań biostratygraficznych pochodził z 25 otworów wiertniczych. Zespoły miospor z badanych utworów zaliczono do dziewięciu wcześniej wyróżnionych jednostek biostraty[...]
EN Detailed stratigraphy of the Tournaisian and Viséan in western Pomerania has been established on conodonts, miospores and ostracods recovered from 25 boreholes. Miospore associations from the Tournaisian and Viséan are assigned to nine biostratigraphic units (zones and subzones) erected earlier. Thr[...]
