Abstract

[We studied the substantial biotic changes in the Moscovian–Kasimovian interval based on an investigation of several sections of the Oka–Tsna uplift and a general overview of the taxonomic changes in eastern and northern Laurussia. The interval corresponds to the interglacial episode between the Glacial II and Glacial III events. The event is indicated by a drop in the diversity and partial extinction of massive colonial corals, the fusulinid genus Fusulina, species of Fusulinella, and taxonomic changes in conodonts shown by data from measured sections. Several levels of disconformities, subaerial exposure, and palaeosols are observed. The cyclic sedimentation is generally displayed by replacement of grainstone to dolostone or secondary micritized mudstones, which allows a subdivision to be made of the elementary cycles bounded by submerged or exposure unconformities. A palaeosol profile with the development of Microcodium was found at the top of the Domodedovo Formation in the Kasimov quarry. The occurrence of erosion surfaces increases into the upper Domodedovo Formation and Peski Formation. The change in sedimentation is marked by an input of siliciclastic material, which allows the lower boundary of the Voskresensk Formation to be traced by a red clay deposit. The biostratigraphy of the recently measured Kasimov and Maleevo sections is based on conodonts, which enable us to recognize some zones from the southern part of the Moscow Basin, utilizing fusulinids and rugose corals. The isotope data show a positive trend of δ18O and a negative trend of δ13C at the base of the Peski Formation (upper Moscovian), coinciding with a palaeosol with Microcodium.]
