| 摘 要： | 浙江长兴煤山剖面Ｇｒｉｅｓｂａｃｈｉａｎ期地层由一系列多级泥—灰岩层束旋回所组成，层束的结构型式和空间叠置关系是层序地层中层序和体系域识别和区分的良好标志。旋回层束中碳酸盐岩含量变化的时间序列分析表明，其形成机制与米兰柯维奇天文气候周期密切相关，从而将地层研究的分辨率提高到了万年级（１０４年）。

| Abstract: | The Griesbachian strata of the Meishan
Section,Changxing County,Zhejiang Province,Southeast China are composed of a series of
multievel cycles of the mudrock limestone bundles.The composition of the bundles and their
stacking patterns are the excellent markers for distinguishing and identifying the sequence and
system tracts in sequence stratigraphy.The time series analysis of the carbonate contents of
the bundles shows that the formation of the bundles and the higher cycles was closely related
to the astronomical Milankovitch climate cycles,so that the resolution of the studied strata is
greatly improved up to the scale of 10 4 years. |
