Beyond Byerlee friction, weak faults and implications for slip behavior (2019)
Journal Article
Collettini, C., Tesei, T., Scuderi, M., Carpenter, B., & Viti, C. (2019). Beyond Byerlee friction, weak faults and implications for slip behavior. Earth and Planetary Science Letters, 519, 245-263. https://doi.org/10.1016/j.epsl.2019.05.011

Some faults are considered strong because their strength is consistent with the Coulomb criterion under Byerlee's friction, 0.6<μ<0.85 . In marked contrast, numerous studies have documented significant fault weakening induced by fluid-assisted reacti...

Experimental Insights Into Fault Reactivation in Gouge‐Filled Fault Zones (2019)
Journal Article
Giorgetti, C., Tesei, T., Scuderi, M., & Collettini, C. (2019). Experimental Insights Into Fault Reactivation in Gouge‐Filled Fault Zones. Journal of Geophysical Research, 124(4), 4189-4204. https://doi.org/10.1029/2018jb016813

Faults in the brittle crust constitute preexisting weakness zones that can be reactivated depending on their friction, orientation within the local stress field, and stress field magnitude. Analytical approaches to evaluate the potential for fault re... Read More about Experimental Insights Into Fault Reactivation in Gouge‐Filled Fault Zones.

Friction of Mineralogically Controlled Serpentinites and Implications for Fault Weakness (2018)
Journal Article
Tesei, T., Harbord, C., De Paola, N., Collettini, C., & Viti, C. (2018). Friction of Mineralogically Controlled Serpentinites and Implications for Fault Weakness. Journal of Geophysical Research. Solid Earth, 123(8), 6976-6991. https://doi.org/10.1029/2018jb016058

Serpentines are common minerals in several major tectonic faults in a variety of geodynamic settings and have variable frictional strength and complex deformation processes. Here we present friction experiments carried out on a suite of serpentine sa... Read More about Friction of Mineralogically Controlled Serpentinites and Implications for Fault Weakness.

Strength evolution of simulated carbonate-bearing faults: The role of normal stress and slip velocity (2017)
Journal Article
Mercuri, M., Scuderi, M. M., Tesei, T., Carminati, E., & Collettini, C. (2017). Strength evolution of simulated carbonate-bearing faults: The role of normal stress and slip velocity. Journal of Structural Geology, 109, 1-9. https://doi.org/10.1016/j.jsg.2017.12.017

A great number of earthquakes occur within thick carbonate sequences in the shallow crust. At the same time, carbonate fault rocks exhumed from a depth < 6 km (i.e., from seismogenic depths) exhibit the coexistence of structures related to brittle (i...
