湖南作为上泥盆统建阶的标准地区,已经有比较详细的研究;但就利用牙形刺作为分层对比依据的工作成果来说,却至今未见系统报道,是个尚待人们去填补的领域。通过对湘中、湘南地区七条剖面(图1)牙形刺的研究,在临武和东安两条剖面(351块次样品)上获得了较为系统的资料(仅台型分子即达13属101个种,并发现新种12个),从而为建立湖南上泥盆统牙形刺序列,积累了一定的资料。 As a standard area for the construction of the Upper Devonian, Hunan has already studied in more detail. However, it has not yet been systematically reported that the use of conodonts as a basis for the work of stratification contrast is yet to be filled field. Through the research on the conodonts of seven sections (Fig. 1) in central and southern Hunan Province, more systematic data were obtained on two profiles (351 samples) of Linwu and Dong’an (only 13 loci Species and found 12 new species), so as to establish the Upper Devonian conodont sequence in Hunan, and accumulated some data.
