ANÁLISE DA PERIODICIDADE DOS FOLHELHOS NEGROS DO POÇO DSDP-530 (BACIA DE ANGOLA): UM ESTUDO COMPARATIVOI ENTRE A ANÁLISE ESPECTRAL UTILIZANDO HARMÔNICOS E WAVELET

A cyclostratigraphic analysis was carried out on a Cenomanian-Turonian sedimentary succession sampled in the well 530A of Deep Sea Drilling Project. This well-defined cyclic sedimentary ´deposit composed of marlstones, siltstones and black shalestones couplets, allowed to compare two different spectral analysis method. The spectral analysis using Morlet Wavelet Transform performed on the colour log ofthe core 98 shows to be advantageous compared...
