The distribution features of foraminiferal assemblages in the Upper Viséan deposits of the reference wells 1 Melekess and 1 Buzuluk are investigated. According to the ratio of the structural components of rocks and their structural features 7 microfacies, characterizing the open shallow shelf and the coastal–marine depositional environments are distinguished in the carbonate sediments. The structure of benthic biota assemblages was revealed. The foraminiferal assemblages are described, taking into account the taxonomic diversity, frequency of occurrence and a degree of preservation.
