• Resumen

  • The statistical analysis of folding-related fracture distributions is a well known tool to obtain structural constraints on fault-fold kinematic evolution. In this work we illustrate the fracture pattern exposed in the Fiastrone anticline (northern Appenines) to determine the relationships between longitudinal fracture patterns and fold growth. Results indicate a mostly syn-folding origin, with a fracture network dominated by hinge perpendicular extension in the crest and hinge perpendicular compression in the fold limbs.
