Andrews (1980) observed that celadonite forms on fissures open to the top of the volcanic pile (with presence of nannofossils), which is significant in terms of the probable origin of the fluids from which celadonite forms.

As a result from the ramp morphology and controlled by regional tectonics and sea level changes, the thickness of these units increases towards the west, which are biostratigraphically well constrained due to the abundance of benthic and nektonic fauna, namely ammonites and calcareous nannofossils (Silva et al., 2011; Duarte et al., 2010; Oliveira et al., 2007; Dommergues and Mouterde, 1987; Mouterde, 1953, 1967) (Fig.
