Chemostratigraphic correlation for A, B and C wells, with the plotted geochemical profiles for Sr/Ca, Zr/Th, Si/Zr, Si/K, K/Rb and Mn. GR – Gamma Ray and DT – acoustic log travel time (sonic log). The transversal dotted lines plotted on each track shows the threshold values used to characterize each geochemical zone.
