| 摘 要： | 老挝万象地区的含盐地层称为塔贡组(E1tg)。该组可划分为三个岩性段,每个岩性段均由下部膏盐层、上部陆源碎屑岩组成,均属湖泊沉积。该套地层的介形虫属Sinocypris—Cypris(Cristocypris)—Parailyocypris组合、轮藻属Peckichara—Obtusochara组合,属古新统。岩石地层、生物地层及年代地层上,该组与我国滇西地区的勐野井组(Em)较为相似。

| Abstract: | The salt-bearing strata in Vientiane area, Laos are called Thangon Formation(E_1tg), which can be divided into 3 lithological members. And every lithological member is composed of the lower gypsiferous salt bed and the upper terrigenous clastic rock, which belongs to the lacustrine sediment. The geological period of Sinocypris-Cypris(Cristocypris)-Parailyocypris Ostracoda assemblage and Peckichara-Obtuschara Charophyta assemblage belongs to Palaeocene. In lithology, stratigraphy, biostratigra- phy and chronostratigraphy, Thangon Formation is relatively similar to Mengyejing Formation(E_1m) in the area of West Yunnan, China. |
