综合分析台地碳酸盐岩中的标准化石和同期盆地层序的几何关系,以及在盆地内沉积的火山碎屑岩层中单颗粒锆石 U-Pb 年龄,可以断定,延续时间小于5Ma 的中三叠世 Latemar 台地内部每一旋回层序的时间间隔很短。因而,排除了 Latemar 地区600个台地旋回大部分是受岁差诱导的米兰科维奇频段海平面变化所控制这一认识。仅仅通过估算和对旋回叠置模式时空变化的图解分析,是不可能对古代台地碳酸盐岩中的米兰科维奇频率得出一个清晰的认识。
Based on a comprehensive analysis of the geometric relationship between the standard fossils in the platform carbonate and the sequence of the basins in the same period and the zircon U-Pb ages of single grains in volcaniclastic rocks deposited in the basin, it can be concluded that the middle Triassic with a continuation time less than 5Ma The interval of each cycle sequence in the Late Late Terraces is very short. Thus, it is ruled out that most of the 600 platform cycles in the Latemar area are controlled by the precession-induced changes in the sea level at the Milankovitch band. It is impossible to draw a clear picture of the Milankovitch frequency in the ancient platform carbonate rocks simply by means of the graphical analysis of the temporal and spatial variations of the cyclonic superimposed model.
