Early Carboniferous microspores from Novachene Borehole, Central North Bulgaria

Abstract

The paper presents tne results of palynostratigraphyc studies of Carboniferous rocks from Novachene Borehole. The age determination is based on miospore ranges from the Upper Tournaisian to the lower-middle part of the Visean. The identified microflora includes the following taxa: Retispora lepidophyta, Verrucosisporites nitidus, Schopfites claviger, Raistrickia clavata, Crassispora trichera, Diatomozonotriletes saetosus and Lycospora pussila. The sediments from Novachene contain spores attributable to the part of Biozones PL, PC, CM, PU (Westeuropean subdivision).
