Modo de extension de la corteza y formacion del Sistema Extensional de Cerralvo, sur del Golfo de California, a partir de datos de reflexion sismica en 2D

Abstract: En este trabajo realizamos un análisis cinemático del Sistema Extensional de Cerralvo (SEC), al sur del Golfo de California (GC) y proponemos un modelo de extensión cortical a partir del procesado e interpretación de 57.4 km de datos de sísmica de reflexión multicanal en dos dimensiones. La imagen sísmica muestra que en el SEC las fallas principales buzan hacia el este con ángulos entre 10 y 25° formando un rift asimétrico. La magnitud de extensión horizontal calculada es de 28.0 km, lo que corresponde a un fa… Show more

“…(c) Overview map with location of the Guaymas Basin within the Gulf of California. much greater than typical pelagic rates of 5-50 mm/ kyr Calvert, 1966;Curray et al, 1982a) presently observed in the southern GOC (e.g., Ramírez-Zerpa et al, 2022), but are in line with sedimentation rates documented for the Tiburón, Wagner, and Laguna Salada basins north of GB (e.g., Aragón-Arreola & Martín-Barajas, 2007;Contreras-Pérez et al, 2012;Dorsey, 2010). Sediment thickness in the GB is in the order of 1-3 km (Lizarralde et al, 2007;Teske et al, 2021a).…”

“…(e.g. et al, 2019;Martín-Barajas et al, 2013;Neumann et al, 2017;Persaud et al, 2017). Of the segments accommodating spreading, the 50 km Alarcón Rise is the longest and lies at the Gulf's mouth between the southern tip of the Peninsula and mainland Mexico (Figure 1A, Clague et al, 2018).…”

“…Deformation in the Gulf of California (GC) is accommodated by a large variety of extension mechanisms that include high angle normal faults, gravitational spreading, crustal‐scale stepovers, en‐echelon extensional zones or sub‐basins in areas of basaltic underplating, etc. (e.g., Bialas & Buck, 2009; Contreras‐Pérez et al., 2012; Macias‐Iñiguez et al., 2019; Martín‐Barajas et al., 2013; Neumann et al., 2017; Persaud et al., 2017).

“…Despite recent progress in understanding the rifting dynamics of the Gulf of California (GC), significant gaps in information still exist due to extensive unexplored regions (Lonsdale 1989;Aragón-Arreola et al 2005;González-Fernández et al 2005; Aragón-Arreola and Martín-Barajas 2007; Lizarralde et al 2007;González-Escobar et al 2010;Contreras-Pérez et al 2012;Martín-Barajas et al 2013;Ramírez-Zerpa et al 2022). This lack of information hinders our ability to establish a comprehensive context for the kinematics responsible for the opening of the GC, especially in the case of the pull-apart basins in the southern GC (Fig.…”
