The effective stress law at a brittle‐plastic transition with a halite gouge layer
We investigated the effect of pore pressure P f near the brittle‐plastic transition (BPT) for a halite (NaCl) shear zone. Our series of precut friction experiments with a gas‐medium apparatus with temperature T ≤ 200°C, confining gas pressure P c ≤ 150 MPa and P f ≤ 140 MPa, revealed that a tanh...

| 520 | |a We investigated the effect of pore pressure P f near the brittle‐plastic transition (BPT) for a halite (NaCl) shear zone. Our series of precut friction experiments with a gas‐medium apparatus with temperature T ≤ 200°C, confining gas pressure P c ≤ 150 MPa and P f ≤ 140 MPa, revealed that a tanh connection between the brittle and plastic regimes works well even at elevated P f , with a coefficient for P f in an effective stress law α being unity. Plastic deformation around the real contacts independent of the mean stress results in α = 1 regardless of the ratio of the real contact area A r / A . The functional dependency of the shear strength on the effective normal stress may deviate from a linear dependency with increasing A r / A . The present findings support a smooth transition in a hypothetical steady state strength profile around a BPT, providing new insights in geologically obtained paleostress data in exhumed mylonitic shear zones. An effective stress law of a shear zone near a brittle‐plastic transition was investigated The connection described by Shimamoto and Noda (2014) works even at elevated pore fluid pressure The coefficient alpha in the effective stress law should be 1 regardless of the real contact area | ||

The effective stress law at a brittle‐plastic transition with a halite gouge layer |
| abstract |
We investigated the effect of pore pressure P f near the brittle‐plastic transition (BPT) for a halite (NaCl) shear zone. Our series of precut friction experiments with a gas‐medium apparatus with temperature T ≤ 200°C, confining gas pressure P c ≤ 150 MPa and P f ≤ 140 MPa, revealed that a tanh connection between the brittle and plastic regimes works well even at elevated P f , with a coefficient for P f in an effective stress law α being unity. Plastic deformation around the real contacts independent of the mean stress results in α = 1 regardless of the ratio of the real contact area A r / A . The functional dependency of the shear strength on the effective normal stress may deviate from a linear dependency with increasing A r / A . The present findings support a smooth transition in a hypothetical steady state strength profile around a BPT, providing new insights in geologically obtained paleostress data in exhumed mylonitic shear zones. An effective stress law of a shear zone near a brittle‐plastic transition was investigated The connection described by Shimamoto and Noda (2014) works even at elevated pore fluid pressure The coefficient alpha in the effective stress law should be 1 regardless of the real contact area |
