RT Journal Article T1 Análisis del plegamiento al Norte de Biescas (Zona Surpirenaica, Pirineos centrales) T1 Folding analysis in a cross-section (North of Biescas, South Pyrenean Zone, Central Pyrenees) A1 Rodríguez, Lidia A1 Cuevas, Julia AB This paper provides the first results of a structural study in a cross-section in the Central Pyrenees(South Pyrenean Zone, North of Biescas), bordered on the north by Palaeozoic rocks of the Axial Zone.The geometric features of the folds, their orientations and relationships with the foliation are detailed fromthe structural analysis. Asymmetric south-verging chevron folds, with an E-W axis gently plunging orsubhorizontal, are predominant. They admit the regional foliation as the axial plane foliation, with an E-Wof medium strike and dips of 50º northwards. Advanced structural studies will allow a more detailedknowledge of the processes originating the described structures and may specify the alpine deformation inthe palaeozoic rocks within this region YR 2008 FD 2008 LK http://hdl.handle.net/10272/8208 UL http://hdl.handle.net/10272/8208 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
