Folding development in the Penibetic Units around the western front of the Alboran Domain (Betics)

Miocene shortening within the Penibetic Units (South Iberian Domain) near the western end of the Alboran Domain (Betics hinterland) developed in two phases with different morphologic and structural characteristics. F1 folds are angular, asymmetrical, NW- to SW-vergent, and early-to-middle Miocene in...

Descrição
Resumo:Miocene shortening within the Penibetic Units (South Iberian Domain) near the western end of the Alboran Domain (Betics hinterland) developed in two phases with different morphologic and structural characteristics. F1 folds are angular, asymmetrical, NW- to SW-vergent, and early-to-middle Miocene in age; they develop a widely distributed spaced cleavage, f, folds, late Miocene in age, result in upright or box shaped, kilometric-scale folds with no associated cleavage. The spatial zonation of the F, folding style suggests that the folds were partially generated by shearing during the overthrusting of the Alboran Domain
