The Zipaquira Anticline (ZA) is an assimetrical fold with variation in the strike of fold axis and affected by some transverse faults (Transverse Zones) along its extension. The main fracture set in the ZA was formed in a prefolding stage (J1), controlling the formation and propagation of sin-folding fractures (J2). Another fracture set (J3) was only recognized near the Zipaquira Lineament where several factors converge to deform considerably the rocks (e.g. Salt diapirs). We calculate the stress tensor from kinematic data, resulting in fractures formed in an extensional environment induced by diapir intrusion in the fold core. According to the transverse sections and previous considerations, thickness variation in Upper Cretaceous-Paleocene formations may indicate the onset of the pre-Andean Orogeny and the uplift of separated blocks, controlled by the transverse zones. 2016 artículo científico 0120-3630 https://www.redalyc.org/articulo.oa?id=169543502003 es http://www.redalyc.org/revista.oa?id=1695 Boletín de Ciencias de la Tierra application/pdf Universidad Nacional de Colombia Boletín de Ciencias de la Tierra (Colombia) Num.39 |
