Description
The timing and duration of fold-related deformation-including layer-parallel shortening (LPS)-related to fold growth, are difficult to estimate because of a lack of data in most natural cases. We propose an original combination of direct and indirect dating methods to reconstruct the burial-deformation history of the Mesozoic carbonates that crop out in the Cingoli Anticline in the Umbria-Marche Apennine Ridge. The Cingoli anticline displays an arcuate shape in map view, trending N140 in its northern part and N160 in its southern part). We first study the fracture-stylolite network to characterize the successive stages of deformation. Several sets of mesostructures were discriminated according to their orientation and relative chronology:(i) NS trending vertical joints (after unfolding), likely related to foreland flexure/forebulge development;(ii) N045 trending vertical, bedding and fold-axis perpendicular joints/veins …
