摘要
米兰柯维奇旋回在地质历史时期具有相对的稳定性,其在地层中的记录可以作为一座精确的“沉积物钟”和辅助的测龄工具.利用小波分析从测井曲线中识别米氏旋回,可以确定地层沉积的持续时间.通过与其他方法定年结果比较,表明该方法具有一定的准确性和可靠性。
The Milankovitch cycle, whose records in strata can be considered both as an accurate “sediment clock” and as an auxiliary dating tool, is relatively stable in the geologic history. The identification of Milankovitch cycle from the logging curves by means of the wavelet analysis can be used to determine the continuous period of the stratigraphic sediments. Compared with other dating methods, this method shows certain accuracy and reliability. In addition, this method can also be applied to the dating of clastic rocks in other regions.
