Resum
A multifractal approach can help understand the controversy as to whether bed thickness obeys power law or log-normal distributions. In particular, late Turonian-early Coniacian bedding thickness distribution shows multiscaling properties related to structures that can be described as a collection of intertwined fractal subsets, which exhibit power-law scaling with a range of exponents and dimensions. The multifractal spectra discriminate between sections in different sedimentary environments (coastal, mixed and shallow marine). The correlation dimension (D2) is equivalent to the thickness distribution dimension (Dt ), and in the studied area has been used as a discrimination factor in the analysis of the distribution of sedimentary environments. Therefore, multifractal analysis can be considered as a useful tool to differentiate stratigraphic sequences, and can assist in the analysis of cyclicity and correlation at basin scale.
