一条新发现的深水相泥盆系—石炭系界线剖面:中国贵州紫云火花剖面
The Huohua section: a new Devonian-Carboniferous boundary section of deep-water facies in Ziyun County, Guizhou Province, China
摘要
Abstract
This paper introduces a new section of the Devonian-Carboniferous boundary in Huohua area,Ziyun County,Guizhou Province,South China.The Huohua section of Upper Devonian and Lower Carboniferous is well-outcropped along a new countryside road.In this section,the D-C boundary beds can be grouped into three litho-units:the Daihua Formation,the Changshun Shale and the "Wangyou Formation",fiom which more than 30 conodont samples were collected and processed.According to our current study,some important conodonts in the Daihua Formation and the Changshun Shale have been recognized,such as Palmatolepis tenuipunctata,Pa.glabra,Pa.marginifera,Pa.gracilis,Polygnathus vogesi and Polygnathus purus purus.A few conodonts have been found from the Wangyou Formation,such as Polygnathus communis and Hindeodella subtilis.Based on the comparison with the Muhua section in Changshun county and the Hasselbachtal section in Germany in lithology,sedimentology and conodont biostratigraphy,the D-C boundary could be temporarily placed between Bed 25 and Bed 26,namely between the Changshun Shale and the Wangyou Formation.关键词
