| 摘 要： | 浙江桐庐栖霞组可划分为二个(竹蜓)带:上部为Cancellina neoschwagerinoides-Verbeekina grabaui带,归属祥播阶;下部为Misellina claudiae带,归属罗甸阶.栖霞组被划分出3个正层序和6个四级层序.高频旋回层研究表明:栖霞组主要的成岩环境有台地相、浅海陆棚相和盆地相三种类型,从下至上总体反映为台地向盆地的演化环境.

| Abstract: | The Qixia Formation in the Tonglu area of Zhejiang Province can be divided into two fusulinid biozones.the upper Cancellina neoschwagerinoides-Verbeekina grabaui zone of the Xiangbo Stage and the lower Misellina claudiae zone of the Luodian Stage. The Qixia Formation includes three 3rd-order sequences and six 4th-order sequences. On the basis of sedimentary cycles of the Qixia Formation ,three depositional facies can be recognized.platform facies, shallow sea continental shelf facies and basinal facies. The Qixia Formation records a deepening upward sequence,shifting from platform to basin facies. |
