贵州省紫云县宗地剖面产出早石炭世大塘期至早二叠世栖霞期连续的■类化石序列。研究结果显示:该段地层中共产出■类36属453种(包括14个新种、14个亚种、47个相似种、18个变种以及30个未定种)。依据化石组合特征,可以识别出13个■类化石带,从老至新为Eostaffella-Eostaffellina富集带,Pseudostaffella富集带,Profusulinella deprati延限带,Profusulinella chaohuensis-P.fenghuangshanensis间隔带,Fusulina-Fusulinella富集带,Protriticites ziyunensis sp.nov.富集带,Triticites hobblensis延限带,Triticites panteleevi富集带,Spha-eroschwagerina subrotunda延限带,Eoparafusulina ovata富集带,Staffella-Pseudoendothyra组合带,Miselli-natermieri富集带,Misellina pamirensis-Misellina ovalis共存延限带。依据各带中的■类属种分布,宗地剖面的■类化石带序列可以很好地与中国华南、北美得克萨斯、日本中部和俄罗斯等地区同期的■类化石序列对比。
The Zongdi Section of Ziyun County, Guizhou Province, produces a series of continuous fossil sequences from Datang Period to Early Permian Qixia Period in the Early Carboniferous. The results show that there are 453 species (including 14 new species, 14 subspecies, 47 similar species, 18 varieties and 30 undetermined species) belonging to 36 genera in this section. According to the characteristics of fossil assemblages, 13 fossil zones can be identified from Eostaffella-Eostaffellina enrichment zone, Pseudostaffella enrichment zone, Profusulinella deprati extension zone, Profusulinella chaohuensis-P.fenghuangshanensis zone, Fusulina-Fusulinella Enrichment zone, Protriticites ziyunensis sp.nov enrichment zone, Triticites hobblensis extension zone, Triticites panteleevi enrichment zone, Spha-eroschwagerina subrotunda extension zone, Eoparafus ulina ovata enrichment zone, Staffella-Pseudoendothyra combination zone, Miselli-natermieri rich Set belt, Misellina pamirensis-Misellina ovalis coexistence of the extension zone. According to the distribution of the genera in each belt, the fossil zone sequence of the parcel of the parcel can be compared well with the fossil sequences of the same period in South China, North America, Texas, Central Japan and Russia.
