1978年,笔者对江西崇义县思顺—过埠一带的奥陶系进行了详细的研究,证实该地有印渚埠期、宁国期、胡乐期、(氵韓)江期、石口期和五峰期含笔石动物群的地层。由于肖承协等(1975)对该区牛皮湾一带的宁国期地层及笔石动物群已有论述,本文只报道该区中、晚奥陶世的含笔石地层。我国中奥陶世晚期((氵韓)江期)和晚奥陶世早期(石口期)地层,除祁连山和赣西南地区外,均为壳相沉积。因此,对崇义的(氵韓)江期和石口期笔石地层的研究,将为我国奥陶系的划分和对比提供一些新资料。
In 1978, the author carried out a detailed study of the Ordovician in the Shunshu-Buqu area of Chongyi County, Jiangxi Province, confirming that there are such places as Yinchu Port, Ningguo Period, Hulei Period, Qionghan Period, Shihkou Period and Wufeng Stratum containing pen-stone fauna. Since Xiao Cheng-sheng et al. (1975) described the Ningguo Period strata and penolith fauna in the area of Niupi Bay in this area, only the penolith-bearing strata in the middle and late Ordovician were reported in this paper. In the Late Ordovician ((氵 Han) Jiang Period) and Late Ordovician (Shikou Period) strata, except for the Qilian Mountains and southwestern Jiangxi Province, they are all facies deposits. Therefore, the study of Chongyi (氵 Han) Jiang Shek and Shi Kou Period penStone strata will provide some new information for the division and comparison of Ordovician in China.
