大槽子剖面位于云南省宁蒗县城以南约25km处,是原云南省第二区域地质测量队于70年代发现和测制的,并对泥盆纪地层作了划分、对比和命名。由下而上分别是大瓜坪组、大槽子组、碳山坪组、烂泥箐组和干沟组,其中将大瓜坪组划归早泥盆世晚期,大槽子组和碳山坪组分别与艾菲尔阶和吉维特阶对比,烂泥箐组和干沟组分别与弗拉阶和法门阶对应。大槽子剖面地处泥盆系青藏区和华南区交界处(王钰等1982),且地层发育较
Located about 25km south of Ninglai County, Yunnan Province, the large trough section was discovered and measured by the Second Regional Geological Survey Team of Yunnan Province in the 1970s. The Devonian strata was divided, compared and named. From the bottom up, they are DaGuaping Formation, Dacaozi Formation, Carbon Shanping Formation, Shanyitiao Formation and Gangou Formation, of which the DaGuaping Formation is located in the late Early Devonian, Dakazi Formation and Carbon Shanping Formation Respectively compared with the Eifelian and the Jiewitt, the Shandamu and Gougou groups correspond to the Frat and Famenian, respectively. The large trough section is located in the Devonian Qinghai-Tibet region and the junction of South China Region (Wang Yu et al 1982), and stratigraphic development than
