Abstract

This paper (see also part I, Kullberg & Rocha, 2014) intended to clarify the proposals presented on the infilling models of the Lusitanian Basin, focusing in particular on the more complex sector and time interval, in this case the central sector throughout the Kimmeridgian-Tithonian. Thus, an integrated model of the lithostratigraphic units controlled by the chronostratigraphy of ammonite faunas, for almost the entire studied range (Upper Jurassic) is defined, and we therefore propose an evolution marked by three sedimentary mega-sequences (I-K), of which the latter two are described here (J-K), limited by regional discontinuities (D9-D12); this proposal is based on a tectonic model already established for the Basin, namely in what concerns the end of the 2nd rifting episode (see part I, Kullberg & Rocha, 2014) and the development stages of the3rdrifting episode.
