In western Henan, Late Palaeozoic coal measures are completely developed and well exposed. A great deal of research work on biostratigraphy was done by predecessors. After systematic palaeomagnetic studies, we have confirmed the existence of the Permian Kiaman reversed polarity epoch in the study region. Its palaeolatitude varied from 11.2° N(P,) to 15.6°N(P2). This provides important evidence for the view that this region was situated in a low latitude climatic zone in this period and gradually moved northwards from the tropic rain forest climate area to the tropic arid-humid seasonal climate area during this stage.
