Abstract

The Iberian Massif, in the western part of the Iberian Peninsula, constitutes a nearly complete section of the Variscan oro- gen. Since the 1990s it has been target of different geophysical studies to unravel the crustal structure. However, there was a remarkable lack of deep seismic sounding data in its central part – the Central Iberian Zone. To fill this gap, a wide-angle seismic reflection and refraction experiment, CIMDEF (Central Iberian Mechanism of DEFormation), was acquired in 2017 and 2019. CIMDEF consists of three NNW-SSE and E-W oriented profiles ranging between 130 and 330 km in length. These profiles run through the Duero basin, the Central System and the Tajo basin, allowing us to construct a new P-wave velocity model in this sector of the Central Iberian Zone. Furthermore, it will help to complement previous models in this area based on Global-Phase Seismic Interferometry and ambient seismic noise (Andrés et al., 2019, 2020), thus providing new constra- ints to validate the accuracy of passive seismic methods at lithospheric scale in the Variscan orogen.
