“…In this study, the photogrammetric method was used to acquire very detailed profiles of seven fault rock hand specimen samples, which were collected from the main slip surfaces of active normal faults in the Central Apennines of Italy (Fig.1a, Ghisetti and Vezzani, 1999, Tondi, 2000, Agosta and Aydin, 2006. In order to calibrate the methods and test its applicability in the field to natural fault surfaces, four additional fault surface models were produced.…”

A C C E P T E D M A N U S C R I P T AbstractFault roughness is a measure of the dimensions and distribution of fault asperities, which can act as stress concentrators affecting fault frictional behaviour and the dynamics of rupture propagation.Studies aimed at describing fault roughness require the acquisition of extremely detailed and accurate datasets of fault surface topography. Fault surface data have been acquired by methods such as LiDAR, laser profilometers and white light interferometers, each covering different length scales and with only LiDAR available in the field. Here we explore the potential use of multi-view photogrammetric methods in fault roughness studies, which are presently underexplored and offer the advantage of detailed data acquisition directly in the field. We applied the photogrammetric method to reproduce fault topography, by using seven dm-sized fault rock samples photographed in the lab, three fault surfaces photographed in the field, and one control object used to estimate the model error.We studied these topographies estimating their roughness scaling coefficients through a Fourier power spectrum method. Our results show scaling coefficients of 0.84±0.17 along the slip direction ACCEPTED MANUSCRIPTA C C E P T E D M A N U S C R I P T 2 and 0.91±0.17 perpendicularly to it, and are thus comparable to those results obtained by previous authors. This provides encouragement for the use of photogrammetric methods for future studies, particularly those involving field-based acquisition, where other techniques have limitations.

“…By means of detailed field and microstructural observations, four main deformation processes representative of increased stages of deformation were identified: (i) compaction and shear strain localization into narrow bands (Aydin, 1978;Shipton and Cowie, 2001;Aydin et al, 2006;Rath et al, 2011), (ii) pressure solution at the grain contacts, with development of discrete pressure solution seams, within the already compacted bands (Rutter, 1983;Groshong, 1988;Liteanu and Spiers, 2009;Croizé et al, 2010c;Zhang et al, 2010), (iii) subsequent shearing of the pressure solution seams (e.g. Alvarez et al, 1978;Agosta and Aydin, 2006;Agosta et al, 2009) and (iv) cataclasis localized along the sheared pressure solution seams (e.g. Engelder, 1974).…”

a b s t r a c tRecent field-based studies documented deformation bands in porous carbonates; these structures accommodate volumetric and/or shear strain by means of pore collapse, grain rotation and/or sliding. Microstructural observations of natural deformation bands in carbonates showed that, at advanced stages of deformation, pressure solution helps to reduce the grain size, enhancing comminuted flow and forming narrow cataclastic zones within the bands. In contrast, laboratory studies on the mechanics of deformation bands in limestones identified grain crushing, pore collapse and mechanical twinning as the micromechanisms leading to strain localization.Here, we present a multidisciplinary field and laboratory study performed on a Cretaceous carbonate grainstone to investigate the microprocesses associated to deformation banding in this rock. A quantitative microstructural analysis, carried out on natural deformation bands aimed at defining the spatial distribution of pressure solutions, was accompanied by a force chain orientation study. Two sets of triaxial experiments were performed under wet conditions on selected host rock samples. The deformed samples often displayed a shear-enhanced compaction behavior and strain hardening, associated with various patterns of strain localization.We constrained the pressure conditions at which natural deformation bands developed by reproducing in laboratory both low and high angle to the major principal stress axis deformation bands. The comparison among natural and laboratory-formed structures, allowed us to gain new insights into the role, and the relative predominance, of different microprocesses (i.e. microcracking, twinning and pressure solution) in nature and laboratory.
