Fault Core Thickness: Insights from Siliciclastic and Carbonate Rocks

Figure 9

Different fault rocks observed in the studied fault cores in Vallone di Santo Spirito, Maiella. (a) Beige carbonate gouge observed in the fault core of a right-lateral strike-slip fault. Note the carbonate fragments that are incorporated in the gouge. (b) Carbonate lens trapped in the fault core of a right-lateral strike-slip fault. (c) White-brownish cemented fault gouge located in the fault core of a right-lateral strike-slip fault. (d) Dissolution features formed in dilation jogs along a strike-slip fault. (e) A cohesive breccia pocket observed in the fault core of a left-lateral strike-slip fault.
