INTRODUCTION

This 5 day Professional training course takes place along the Western Iberian Margin (WIM), between Alentejo Basin (including CAMP and Sines Igneous Complex) and the Lusitanian Basin (including Sintra Igneous Complex and Lisbon Volcanic Complex), in Portugal.

The main objective of the field trip is to highlight the complexity and problematics of interpreting magmatic-related structures on different datasets and at different scales (outcrops, seismic data, potential fields data), while understanding the implications of magmatism in the regional and local structural framework, hydrocarbon maturation, reservoir properties distribution, trap creation and/or destruction, natural hydrogen generation and CO2 sequestration and mineralization.

The West Iberian Margin (WIM) recorded three major magmatic events during Mesozoic. The first is related with the Central Atlantic Central Atlantic Magmatic Provence (CAMP) between c. 200-198 Ma (Hettangian) at the end of the first rifting stage, the second, late Jurassic to early Cretaceous (148-140 Ma) in age, is concomitant with the last rifting phase recorded and the third is the most pronounce and widespread along the margin that occurred in a post-rift context during Late Cretaceous (94-69 Ma).

These magmatic events left excellent exposures along coastal and inland areas, both of intrusive and extrusive nature. Recent 3D seismic acquisition campaigns, together with high-resolution gravity and magnetic data allowed further identification and characterisation of offshore magmatic structures related with these events.

As a consequence, the West Iberian Margin can be used as a natural laboratory to compare between outcrop and seismic data allowing the interpretation of the structural styles associated to magmatism at different scales and comparison with other similar magmatic provinces around the world.
