“…This burial depth implies deposition of 2000 m of Miocene strata before folding occurred. This thickness of the Miocene formations is documented in the UMAR, both in the innermost western part [e.g., Tavani et al, 2008] and in the outermost eastern part [e.g., Petracchini et al, 2012]. In the eastern part of the pre-UMAR, vitrinite reflectance and clay content also predict deeper burial (up to 4000 m), which was related to thrusting of the Ligurian units above the observed strata [Caricchi et al, 2015a[Caricchi et al, , 2015b.…”

“…Stylolites are common deformation features especially in carbonate rocks, and they are important because up to 50% of the initial rock volume can be dissolved at these surfaces [Alvarez et al, 1978] and they strongly impact fault development [Marshak et al, 1982;Gratier et al, 2003;Tondi et al, 2006;Faulkner et al, 2010]. In recent years, stylolites were included in the reconstruction of fold histories in addition to the classical use of fracture and fault patterns [e.g., Tavani et al, 2008Tavani et al, , 2015Petracchini et al, 2012]. In addition, their impact on reservoir properties is debated [Heap et al, 2014].…”

In this study we show for the first time how quantitative stress estimates can be derived by combining calcite twinning and stylolite roughness stress fingerprinting techniques in a fold-and-thrust belt. First, we present a new method that gives access to stress inversion using tectonic stylolites without access to the stylolite surface and compare results with calcite twin inversion. Second, we use our new approach to present a high-resolution deformation and stress history that affected Meso-Cenozoic limestone strata in the Monte Nero Anticline during its late Miocene-Pliocene growth in the Umbria-Marche Arcuate Ridge (northern Apennines, Italy). In this area an extensive stylolite-joint/vein network developed during layer-parallel shortening (LPS), as well as during and after folding. Stress fingerprinting illustrates how stress in the sedimentary strata did build up prior to folding during LPS. The stress regime oscillated between strike slip and compressional during LPS before ultimately becoming strike slip again during late stage fold tightening. Our case study shows that high-resolution stress fingerprinting is possible and that this novel method can be used to unravel temporal relationships that relate to local variations of regional orogenic stresses. Beyond regional implications, this study validates our approach as a new powerful toolbox to high-resolution stress fingerprinting in basins and orogens combining joint and vein analysis with sedimentary and tectonic stylolite and calcite twin inversion techniques.

“…; Lotti, 1926). These exposures are located in the crestal (hinge) region of the late Messinian-early Pliocene Cingoli anticline (Figure 2), northern Apennines, Italy (Menichetti, 1991;Mazzoli et al, 2002;Petracchini et al, 2012Petracchini et al, , 2015Antonellini et al, 2014). We acknowledge that the three studied exposures are sub-vertical across sub-horizontal or shallowdipping alternating chert-limestone beds and no sub-horizontal exposures exist nearby.…”

“…Contractional deformation along the northern Apennines belt is presently active 40-50 km to the north-east and north of the Cingoli anticline, namely in the northern Adriatic basin and Po plain regions (Scrocca et al, 2007;Carminati et al, 2010;Ventura and Di Giovambattista, 2013;Livio et al, 2014). For further stratigraphic and structural information on the Cingoli anticline area the reader is referred to the next sections and past studies (Carloni, 1960(Carloni, , 1964Ciancetti and Nanni, 1989;Calamita et al, 1990;Menichetti, 1991;Marchegiani et al, 1999;Deiana et al, 2002;Mazzoli et al, 2002;Petracchini et al, 2012Petracchini et al, , 2015Antonellini et al, 2014).…”

“…Bonson et al 2007;Childs et al 2009;Faulkner et al 2010). Distribution, quantity, and connectivity of different fault components strongly influence permeability and may vary across and along fault strike, and over time (Lunn et al 2008;Petracchini et al 2012;Schulz and Evans 2000;Shipton and Cowie 2001). Processes like fault-segment linkage and interaction explain some of these observed complex fault geometries (e.g.…”

This study presents a comparative, field-based hydrogeological characterization of exhumed, inactive fault zones in low-porosity Triassic dolostones and limestones of the Hochschwab massif, a carbonate unit of high economic importance supplying 60 % of the drinking water of Austria's capital, Vienna. Cataclastic rocks and sheared, strongly cemented breccias form low-permeability (<1 mD) domains along faults. Fractured rocks with fracture densities varying by a factor of 10 and fracture porosities varying by a factor of 3, and dilation breccias with average porosities >3 % and permeabilities >1,000 mD form high-permeability domains. With respect to fault-zone architecture and rock content, which is demonstrated to be different for dolostone and limestone, four types of faults are presented. Faults with single-stranded minor fault cores, faults with single-stranded permeable fault cores, and faults with multiple-stranded fault cores are seen as conduits. Faults with single-stranded impermeable fault cores are seen as conduit-barrier systems. Karstic carbonate dissolution occurs along fault cores in limestones and, to a lesser degree, dolostones and creates superposed highpermeability conduits. On a regional scale, faults of a particular deformation event have to be viewed as forming a network of flow conduits directing recharge more or less rapidly towards the water table and the springs. Sections of impermeable fault cores only very locally have the potential to create barriers.
