对卡拉拉（方解石）大理岩、白云石大理岩、含硅酸盐方解石大理岩和方解石泥的实心和空心圆柱体进行高速摩擦试验，研究地震滑动过程中碳酸盐断层的强度。在旋转-剪切摩擦试验机中，在0.6-14.7 MPa的法向应力、0.03-1.60 m/s的滑动速率和室温下进行的实验，获得了极低的稳态摩擦系数(
High-velocity friction tests were conducted on solid and hollow cylinders of Carrara (calcite) marble, dolomite marble, silicate-bearing calcite marble, and calcite gouge to investigate the strength of carbonate faults during seismic slip. The experiments, performed at normal stresses of 0.6-14.7 MPa, slip rates of 0.03-1.60 m/s, and room temperature in a rotary-shear friction testing machine, yielded an extraordinarily low steady state friction coefficient (
