The local section at Portela da Vila exposes various Lower Cretaceous non-marine formations representative of the proximal domains of the Lusitanian Basin. This Mesozoic peri-Atlantic basin of the West Iberian Margin contains a thick and diverse tectono-sedimentary record, in which several rifting phases can be distinguished from the Triassic and Jurassic through the Lower Cretaceous series, with a significant infill of marine carbonates and mixed units interbedded by alluvial sequences with sediments derived from the Variscan Massif of Iberia. The samples containing amber examined in this study were collected from lutite beds at the top of the Lugar d’Além Formation, representing the upper part of a finning-upwards sequence of coarse- to medium- and fine, laminated sandstone deposited above marly levels with small Corbulidae bivalves.
