Distribution of joints in the hinge-line culmination of foreland-verging overturned anticlines: an example from the Montagna dei Fiori structure in the Central Apennines of ItalyM Francioni et al.Distribution of joints in overturned anticlines

摘要: The distribution of joints, veins and shear fractures in the Montagna dei Fiori overturned anticline is here reported. Two joint sets, longitudinal transverse to NNW–SSE axial trend, a conjugate system fractures, are recognized. sets have pre-folding development likely related foreland/foredeep flexure. joints were reopened during layer-parallel shortening along with fractures. Then, syn-folding outer-arc extension hinge-line culmination fold-axial parallel extension, both enhanced reactivated, respectively.
