Abstract

In this paper we present the first palaeogeographical maps of the Lusitanian Basin during the Jurassic. We also present the methodology used to produce these maps and discuss the close relationship of the temporal and spatial distributions of facies with the sequence of tectonic events in the basin (already discussed in Part I of this study, this volume). One of the main conclusions is that the main bordering N–S-trending faults were the main tectonic structures that conditioned the facies geometry but only during paroxysmal events; during those short intervals, “instant” modifications of the facies geometry occurred. The other main conclusion is that in the time intervals between the paroxysmal events, the structures that conditioned the facies distribution were the main transfer faults, oriented ENE–WSW, and the sedimentary environments gradually rotated from N–S to ENE–WSW.
